If Paul is an average shooter then I must be a blind man with no hands.
Don't worry about it too much. Ray Charles' reanimated zombie checking in...
very-good...
lol
Yep, I thought the same thing.
I was going to comment on the same thing. If only I could be as "average" as Paul.
Is he still alive? I thought he committed suicide after Paul’s rebuttal video.
Time to rewatch some old videos and prolly re-learn things.
same. paul harrell presentation is god tier in the youtube world
I've been watching older videos just because they're all a treasure trove of information and we're probably not gonna get any new ones from Paul anymore. Roy is very knowledgeable too but he's not as fun to watch.
Does anyone else enjoy the cool factor when Paul reaches into his pocket and pulls out a box of ammo?
Or a 1911...
I imagine a pickpocket would reach in, feel several guns, then proceed to run the other way 😂
To UrbanJungle: Yes. Cheers
This means we can be friends
Shortly after he points to himself, and refers to himself as an “average” shooter, he then takes the rifle from his shoulder with one hand, in a single smooth motion, and proceeds to shoot freehand better than many “average “ shooters could do from a bench.
7.5" guys in the back,
"So you're tell'n me there's a chance"
I have a Saint 7.5” and it’s accurate up to 50 yards with a Romeo red dot. Have t bothered going out to 100... but that’s what what my other AR’s are for...
@@electricgamez5415 exactly!!
Robert Santiago to the people who use .223/5.56 out of a barrel shorter than 10.3”, No! 🗞, bad rifleman! Those manufacturers did not! Work so hard on those rounds for you to fire them out of a barrel that wastes half the powder.
@@Teboski78 Shorty AR's are fun. I think that's enough of a rebuttal.
Electric Gamez , I hit a 14x14 inch Steele target with my 7.5 inch ar at 600 yds , three times in a row with a red dot for a sight .
Paul Harrell - in a nutshell:
•-> “tacticool”: 0%
•-> Professional: 100%
•-> Experienced: 100%
One could argue his professionalism and experience make him more Tacticool than anyone fully geared with all punisher patches.
@@Hcruz487 like his habit of not wearing eye protection?
His eyes don't need protection. His eye protection needs protection from his eyes.
Hcruz487 😂🤣💀
@@chadhaire1711 he is not shooting at hard targets so eye protection is not required
I chuckle when he points to himself as the "average shooter". My 300 yard groups with iron sights would be closer to "minute of barn door".
I'd be off the paper
I am impressed with Paul’s ability to use iron sites. I had great vision (20/15) until my early 40s. Then my arms got to short for me to read. 😂
Iron sites, a dying breed
If you can dependably hit a 3-inch circle at 30 yards, you could probably hit a 30-inch circle at 300, once hold-over and wind-drift are doped.
Bryan, Agreed lol...
Paul at the grocery store:
Employee: Can I help you?
Paul: "I need leather jacket skin, followed by pork steak pectorals, pork ribs, a bag of oranges - to simulate lung tissue, more pork ribs, and 20 bottles of Dr. Thunder 2 litters".
😂
🤣😂🤣
Employee, I saw you coming Paul so I already have it all pulled out for you ,thanks for being such a good customer !
Jugs. The man says jugs lol
@@hotchihuahua1546 Paul to employee, you're an average employee 😅
You're such a gift to the 2A community Paul! Praying for you brother.
Even Paul’s ejected brass makes a great group.
I noticed that, too. Must be an finely tuned adjustable gas block. Or his brass is scared shitless of scattering all over the place.
LOL!!!
@@58allendavis most likely the latter
Lmaaaaaooo
😂😂😂😂😭😭😭😂😅
Guest at Paul Harrell’s BBQ picnic: “Paul, man these ribs are great, how do you get that flavor?”. Paul: “That’s a special orange soda marinade I make myself!”
Ok, that one cracked me up, Still llaughing as im typing. LMAO
ROFLOL! That hit me hard!
And they are quite tender
"Tastes a little leady though..". " Yeah, thats why we take those zeoliie and chlorella drinks afterwards.. . "
Complete with lead fragment seasoning
* casually shoots 300 yards with iron sights *
Me: I cant see that target, what is he shooting at?
Dude has an inspirational level of marksmanship
Try it with 7.62x39 and Ak iron sights. I can do 200, but 300 is not easy.
It really depends on which fornt and rear sight you have on the ak
I would like to see a comparison on the different barrel twist rates, 1/7, 1/8, 1/9, 1/12 and bullet weights .
1/12 + 20inches + m193 = 🍉💥🍉💥🍉💥🍉
That’s a great idea!
MAC (Military Arms Channel) did a video 1/12 vs 1/7 twist with M193 & M855 vs 🍉. Interesting results
Dude. Yes! Great idea!
That was going to be my question. Was there a variable in the rate of twist?
Everyone: “Paul what do you think about the current state of the Union?”
Paul: “Id like to show you a presentation on the various types of AR platforms and their differences.”
When you live in a rural area with limited internet access you tend to give less of a shit about "keeping up with the Kardashians", so to speak.
Paul’s showing everybody what these platforms do when the SHTF he knows what’s up he’s very smart and a true sharpshooter.
Mihajlo limited internet access? Almost Everyone has some form of constant internet in the us (whether mobile or home WiFi or both) unless you live up north (as in deep north) where there isn’t people or internet 😂
dysfunctional orange ... you must not travel to rural areas in the east either. There are quite a few places in the Appalachian mountain chain that has no cell service.
@@dysfunctionalorange Dude where I live it's either DSL or satellite. Neither of which are very fast
Man, there was a lot of 3D action in this video. Brass flying at the camera, savage soda bottle attacks on the camera. I think you made the right call during the test at 300 yards lol it was not the camera's day.
I found it hilarious that Dr. Thunder was responsible for knocking the camera out.
A-a-a-n-d THAT makes .243 thumbs up! Thanks for the video. Good info. & it makes a splash! 😉
Always had a 16 in. AR but just ordered a 20 in. upper. And immediately search for Paul to see if he had tested barrel lengths. As usual, was not disappointed. You are the best Paul. God's blessings on you good man.
Paul is thorough with his presentations!
He answered the questions as soon as I thought of them.
His videos have that 70's/80's vibe. So much so, I thought these were old school videos.
Reminds me of the old drivers ed videos I watched in high school. But...I love it.
I agree 100%
Same i feel like i am watching an Old VHS tape, not a new upload on youtube. Total 80s vibes
That's the way he rolls.
That increases the cool value of the video.
Paul's the God father of shooting videos.
We really need to repeal the NFA.
And fire everyone that works at the

And abolish or defund the ATF.
@Jay Bee Surprisingly more restrictive gun laws passed while the Republicans were in power. And the NRA hasn't done a thing as far as fighting unconstitutional gun laws all they're doing is taking those donations straight to their wallet. Every time I get a letter from them it goes straight to the trash.
@Bill Randall Lately, what BladeKi11a said is true. true. No new gun laws under Obummer but under Trump we get the bumpstock ban, which neither Trump nor the NRA seem to care about. Very bad precedent. The supposedly conservative supreme court won't even hear 2A cases. Now the ATF is considering banning arm braces. CRICKETS from any republicans and the NRA. Until NRA starts doing what it's supposed to do and really fight for the 2A instead of just trying to perpetuate its own existence and line the board's pockets I'm done with them.
Professor 254 Never even noticed that guy. I assumed he’s just a Fudd. And so is Bill Randall. Yes back then the NRA has prevented unconstitutional gun laws in the past but now they became soft. Everyone in the NRA have their own personal gains so the group’s agenda shifted focus and they’re sugar coating shit. The only time they actually did something recently was when Robert Francis O’Rourke was gun ho about banning firearms all together. Every influencer that has the NRA stamped in the background has their speech was paid for. *Cough Colin Noir* There’s other smaller political groups that do a much better job than the NRA.
Whenever I hear vets from the special forces community talk about this, they always say the barrel length doesnt matter so much for accuracy but for how many rounds you need to neutralize a threat at various ranges in places like the mountains of Afghanistan. I think this test shows all barrel lengths are suitable for home defense.
A fookin pencil ✏️ is good for home defense vs nothing
-John Wick
I know it’s a dead comment thread but I’d add that ammo type is important too.
Paul went over this too. The AR is not a good home defense weapon unless you also plan on killing your neighbors
@@Prosecute-fauci A shotgun will blow right through sheet rock. An ar15 won't blast through sheet rock as well, unless you have a short barrel.
@@makepeacewithyourmaker324 did…. Did you even watch Paul’s video on the subject? .223 and 5.56 will go through 2 interior walls plus an exterior wall with ease.
Such a wealth of Knowledge! Paul you will always be remembered as one of the best!
Paul points to himself “average shooter “ . If he’s considered average I don’t want to know what I’d be considered.
Haha aint that the truth.
Impaired, probably. Like me. Lol. And i consider myself a decent shot. But i am not Paul.
I'd love to have a place to shoot where I could line up 6 soda "jugs" side by side and see how well I would do shooting them. My wife would be that I'd hit maybe 2 or 3 of them. I'd be happy if she was right. Our range opens this week so we will see how bad my shooting skills have diminished over the last 2 months.
If Pauls an "Average shooter " then I'm a Martian ! and more importantly , How Good is an "Excellent" marksman ?
100 yards? This (actually) average shooter needs a scope to have any chance at determining a group size!
I admire how Paul never asks for donations, he just thanks everyone for them. I’ve never used Patreon, but I may do that now.
"Don't thank me, pay me".
This is the second or third vid I've seen of his. When I get a job, I'll go on patreon. That Pork must cost a lot of money.
Personally I contribute monthly...not a ton but definitely want to keep Paul making videos and a few bucks a month is worth it to me
@John D I was under the impression that any gun video was demonetized
I did not expect the accuracy of the 10.5 inch barrel to be as good as the 20inch. Very informative.The damage part is the main significant difference that mostly mattered as well. Great job Paul 👍🏻
That's only at close range
@@tedarcher9120not at all... the further the more velocity your bullet has to travel and create a wound cavity point blank goes straight through
@CodeTactical that's not how velocity works. It'll always be fastest at the muzzle.
@@RitzyEG longer barrels have much better muzzle velocity consistency, so with a shorter barrel groups will open up at longer ranges into a keyhole
@@tedarcher9120 I'm sure the groups will open up but idk about keyholing
Wow, I am astounded.
I would have bet totally against the findings of the experiment. I would have bet the shorter barrel would not be in the ball park.
As they say “Live and learn.” Once again Paul is the teacher!!!
Great job Sir !!!!’
The problem with the shortest barrel, the bullet remained intact for the most part!
The 10.5" AR did better than I expected. I thought it would lose a lot more velocity than it did. Thank you.
It seems to be very ammo specific, I've seen some that the rounds are only at around 2100 fps, which is right at 22 magnum range.
Bdkj3e _ But with 20-100% more mass than .22 Magnum
@@HughesEnterprises When one starts analyzing it for mass as well when coming out of shorter barrels, that's where 300 AAC steps in to be the thing that 5.56 can't in under 11.5" barrels.
Might be good to protect one's property, especially if you lived in the desert areas around Nevada or AZ and liked to shoot coyotes on occasion.
Really might not be practical in Fair Oaks though.
Same here. Seems a fine choice for home defense. If you don't mind permanent hearing damage
hmmmmm, my takeaway from this video is that I need at least 3 AR-15's... a 20", a 16", and a 10.5"
You also need a 14.5" P/W because everyone loves an M4gery.
@@desertfox2020 14.5" also.... Check!
@Lieutenant Colonel Nicholson lol I did a 10" AR10 pistol already... Working on a 22 creedmoor AR10 now.
Yes you need all of these and in different colors. Evil black, FDE, OD green, various camo, ah the list goes on.
“YoU doN’t nEeD an Ay ArR FiftEen” No, you need at least three!
As I recall, theres a significantly greater amount of damage when the bullet impacts target above 2900 - 3000 fps because you get a LOT more hydrostatic shock. Anyone whose hunted with higher velocity rounds can probably attest to loss of meat because it's been turned into jelly/mush. Just adding this because the 20" barrel is probably delivering the bullet at greater than 2900 - 3000 fps to the target.
That's true, but there is still enough as long as the bullet is over like 2200 fps.
Hydrostatic shock isn't real unless you hit them in the liver
@edgarburlyman738 Your lungs, heart, kidneys, pancreas, and spinal fluid _disagree!_
Most professional most well-spoken most thorough barrel examination video on TH-cam
Can’t wait to hear Paul’s take on the 10.5” AR as he is somewhat of a traditionalist
He is what we can call, an expert. :)
The XM177E1 had an 11.5" I think
YOU BE THE JUDGE
halo7oo well yeah but all the ARs that he shoots on a regular basis have standard hand guards, iron sights and usually a 20 inch barrel
Reno May sup Reno!?! Didn’t look like it was enough difference... to make a difference.
Paul’s style is refreshing, lots of info and very straightforward.
Iron sights at 300, that’s impressive! With a 10.5 in barrel, utterly impressive!!😁 Showing off without showing off!
you mean the unsafe style of not wearing eye protection?
@@chadhaire1711 I bet you say the same thing after watching porn videos. "She should've had eye protection"
@@chadhaire1711 With closer range targets, Paul actually DOES wear eyepro, he's just off camera.
@@jamesjameson3771 if one of those guns blows up in his face, it will not matter how far away the target is...
I am just amazed how he can grab stuff without breaking eye contact with the camera. It is kind of scary.
If he ever pulls a shakeweight out of his pocket.......
I know right i thought the same thing lol he doesnt break his piercing eye contact lmao
@The Had Matter lol
Peripheral awareness is mighty useful
He's what you would call "a professional".
I'm convinced that the soda and citrus used in the meat target are simply creative ways to marinate and season your pork.
Lol he pointed at himself when he said, “average shooter.” 🙄
I got a laugh out of Pual the average shooter.
Maybe he's comparing himself to like, Hickok?
That's because he is a gentleman.
Maybe he's average and we are all bad.
@@pearljaime2 shh... you're trading in dangerous secrets there my friend.
5:15 I love how flawlessly he unslings his M16a2
Almost like he's done that before, once or twice...
It also gets me every time I see it
The phrase "years of practice" comes to mind.
@Kosove The particular gun in this video has A2 rear sights and a brass deflector, I don't think it's the same rifle as his A1. I do know he has an A1 with A2 handguards also. I could be wrong though!
@Kosove That was an A2. He owns both, though the A1 is his preferred rifle.
Paul’s mannerisms and how he speaks makes me feel like I’m watching Alton Brown in Good Eats. And I love this channel for the same reasons I love Good Eats. Keep it up Paul!
Alton can't hold a candle to Paul's Dr. Thunder Orange Puree Pork Rib Marinade!

@@joshuakang4507 where's his gun collection viewable?
EXACTLY
Love re-watching the old videos best of luck to Paul and his family.
Now that Paul has a short AR, it would be interesting to see how the different 5.56 bullet weights perform in the meat target.
62-75 grain soft points would rek that meat target
Now, that would be an interesting comparison. If the ammo used in the 20" barrel today's demonstration does X amount of damage, what ammo do you have to use in the 10" to achieve the same results?
Type of bullet makes bigger difference then weight.
Hornady specifically makes a SBR 75 Gr soft point that uses a powder optimized for the 10.5 to 11.5 BBL to more fully burn and also reduce muzzle flash. I would be very curious to see how that performs in tests.
@Matthew Lu I'll tend to agree with you, and for my nearly weekly coyote hunting ( a necessity with livestock) I have basically discontinued the use of FMJ and use various HP/match and soft points for effective hits. I am tired and want to go to bed as soon as possible and I am not hunting for fun or sport. I just want them down and not go tracking a wounded animal for ethics sake. I like the concept of a 10.5 for fast on target and minimal weight and tree branches hanging me up but would like to know just how well the specialized lower velocity SBR ammo works with the soft points before I pour all the money into all of that. I need to work smarter, not harder. 200 yards is about the limit of my abilities under the normal night conditions with 300 under the very rare, perfect conditions. > twice in 17 years.
The sugar ants must love Paul on range day!😂
"local ant population swells, threatens nearby town. Paul Harrell sought for questioning"
I'd liked to have seen difference between these barrels on a meat target at 200-300 yards. Great video!
Part two is now on line.
@@PaulHarrell Greetings. Paul I was wondering, if you had the opportunity to shoot the 10.5 inch barrel in low light conditions? if so, did it have a sufficient muzzle flash? Also, any testing with the other barrel lengths in low light conditions. Thanks.
@@JamesSmith-gn9ou 20" has insufficient flash in the dark. I haven't tried 10"
@@JamesSmith-gn9ou 10.5 will produce extreme muzzle flash. Which is why most people, including myself, run a suppressor to prevent flash on pretty much anything below 16", but that's just on my home defense rifle or Hog hunting with NV! If it doesn't bother you, then that is all fine :)
@@PaulHarrell I also have two AR-15s.
The first one I bought was a 16". (Colt).
The second one was a "boot leg" version with a Panther DPMS 20" barrel.
The 20" one drops about 1/3 less at 300 yds than the 16."
BOTH are 7.62×39 SOVIET.
The difference in drop between the 16" and the 20" at 300 yds is quite noticeable. 🤔
That makes sense because from ballistics gel research 5.56 only fragments properly when traveling above 2,500 fps. Really cool to see the difference in the tests!
4:23 The 10.5 in is traveling beyond 2,500 fps. Why didn't it fragment?
@@reptilesgamers00 it probably slowed to below 2,500 before impact.
I worry about the bullet slowing on impact too much to not fragment once it's inside the body. I want that bad boy to practically explode even after punching through a bit

The biggest flaw in this video: the absence of an average shooter
biggest flaw in the video not wearing eye protection.
What was the twist of each barrel.
@@dwightdumas7724 whether 1/7 or 1/9 ........it will NOT make any difference.....so why ask?
@@chadhaire1711 Stabilization of the round. Shorter distance (not shot here) the shorter barrel "is supposed to" stabilize the bullet at a shorter distance whereas the longer barrel is "expected" to stabilize at a longer distance. I have not researched it heavily.
think of it as the read of the bullet is wobbling for "some distance" after it leaves the barrel.
My take aways of this is that the AR15 short or long will deliver. Now you as the shooter must train to be accurate.
@@chadhaire1711 Eye pro is anal retentive if shooting at paper.

This was well timed, I’m buying a barrel tomorrow.
LOL buy 6
So what barrel are you buying?
Just bought a Colt M16A1 (semi only, of course :( ) new production 20" barrel. It is SO gorgeous and I want to take it to the range but can't bring myself to soil her.
@@sharpsvilleBill Pretty guns are useless for that reason unfortunately

Paul, I've always enjoyed your content because of your detail-oriented and straightforward delivery. Much appreciated.
This is an excellent, informative, and very objective video. Thank you very much for taking the time to produce and upload it.
That 50 yard group with the 20" AR was impressive. That is some expert shooting there. I would struggle to hold that group from a rest 😂
He's definitely NOT the 'average shooter' he mentions as the end of the video!
Yeah, I wonder if he picked up a novice shooter and tested the same rifles at the same distance.@@daveholden2711

That's cute xDDD
Cool story bro, poor woman

Hopefully it is a bull barrel and not a pencil profile.
What a well done video. You certainly put a lot of time, effort, and passion into what you do and certainly deliver. Thanks for sharing to help my buddy out to determine what barrel length he wants.
Keep up the great content, Paul. I'd love to see the comparison of .308 out of a 16", 18", 20" and a 24" regarding accuracy and power down range against the meat targets.
Hi Paul, I have done this test several times using a 10.5", 16", 18" and a 20". I have an old fixed 25X Leupold target scope on a MI QD mount that I use just for testing rifles. I have found that the 10.5" gives up nothing to the 20" as far as group size but you do start to see the bullet dropping sooner as the range gets longer. I think the shorter barrel as much stiffer and stays put better resulting in nice tight groups. Loved the video and please keep them cameras rolling!

For OIF 3, we were given M16A2's. Some of us purchased unauthorized M4 uppers...I ended up with a 10.5 inch barrel. With an optic, it was pretty dang accurate for what I needed (nothin' over 100 meters.) This was a great show of accuracy

Great video, Paul! You answered a lot of questions I've had, about the 10.5 barrels! Thank you brother! And, thank you for your service!
One of the best videos comparing barrel lengths. Very informative.
He's descriptive enough I can listen to these videos at work like a podcast.
Hey Paul, fixing for a barbeque? "Nah, headed to the range."
yeah
Pork ribs marinated with orange juice.
Great video. Very detailed and great editing. Really enjoyed it and kept it interesting the whole way through.
Thank you for your time and efforts. Really shredded light on this subject.
I could hear that first underpowered shot on the 16 inch
Looked like a lot of extra smoke out the ejection port as well. That's what I first noticed.
Jefferson Davis Yeah I knew the minute he sent it it wasn’t right
I did too. Obviously a short powder load.
@ Or perhaps grease or other preservative in the barrel? Downloading ammo doesn't normally create that much more smoke so I'm going for some combustible foreign substance down the tube.
I wanted to check that case so bad..... I thought maybe ruptured primer...
I've never fired a gun, and I love this channel. Paul, you're extremely well spoken and present yourself very professionally. Well done on creating a great channel.
Well come on out to the range.
Check out Project Appleseed. There are usually loaner rifles available if state laws allow. Contact the shoot boss ahead of time to make sure. You can have a safe weekend of instruction for a very reasonable cost. It is well worth the investment.
Another fantastic Vid, Paul. I work in a gun shop, and, as I'm sure you know, sales are way up. We experience a variety of skill and experience levels, and it's so handy to be able to refer them to channels like these. Thanks, and keep up the great work! We appreciate you.
Just the info I was looking for thanks for taking the time to make this video. Really appreciate all the effort put into it.
Width is much, much more important than length. It's 2020, everyone should know this by now.
But as Paul pointed out, the most is down to the shooter.;))
Guy: *pulls out bazooka* is this wide enough?!?
Woman: *horrified*
Shooting 5.56NATO through a 7.62NATO barrel will be very different, yes.
Width is definitely more important than length.
Those of us who are "professionals in the industry" call it "girth".
While in the prone your breathing reminded me that a breathing tutorial could also shed light on accuracy. Exhaled shot, inhaled shot and breathing shots. Something that was job one when I taught my kids.
I dont even know what an inhale shot, exhale shot, or a breathing shot even means. Mine was a couple of deep slow breaths in and out. And on the shooting breath, deep breath, then only let half of it out and hold. Nothing left but your heartbeat to deal with after that. It looks like Paul's is a variant of that, just instead of half breath out, takes the full breath and holds.
I'd love a video on marksmanship from Paul. I've watched a lot of gun videos and I don't think I've seen anyone shoot better offhand.
Really nice video - pictures speak louder than words! Like youn said - a difference, but a small difference with the lounger barrel. Thanks - much appreciated!
I love the videos this channel puts out. They're very informative and get to the point.
Hey Paul, I would love to see a lengthy video discussing a plethora of shooting positions and techniques, as well as their uses.
You're such a badass man, even though I know you'd never admit that. I've learned so much from your channel, thanks for sharing all of your great knowledge and experience with us!
Always a thorough and complete analysis. Thank you

This same test would be interesting with 9mm. I am talking about 7", 10", and 16" barrels. I don't know of any 20 " 9mm barrels. Keep up the good work. I find myself constantly refrencing your videos on many topics because the are so well thought out and executed. thanks
We have a presentation on 9X19 PCC's
@@PaulHarrell Hey Paul!🤙
ballistics by the inch is a great website that shows effects of barrel length on many common calibers. Here is a link to the chart for 9mm. There are diminishing returns past about 8". See how the muzzle energy is almost flat and you gain very little going all the way from 8" to 16". www.ballisticsbytheinch.com/megraphs/9mm.html
@@Plur307 That it. There is no reason for a 20 inch 9mm barrel when the round is out of gas before 16 inches. The sweet spot seems to be between 7 and 10 inches which is the barrel length range for most submachineguns. That isn't a coincidence. If you're going to suppress it, then shorter like 4-5 inches might be better to avoid the hypersonic crack.
pistol cartridges are designed to burn their charge very early (for obvious reasons). They aren't going to put more charge than is needed for a pistol, so you aren't going to be getting any significant thrust past a certain point.
As a matter of fact, due to friction between the round and barrel, at some point, the pressure isn't enough to beat the friction and you get velocity LOSSES with bigger barrel.
Not sure of the numbers, but I bet around 16" is where any more barrel is not justifiable.
This is a great demonstration video. I already had a 16” Ruger AR-556 and a 20” M16A4 clone, but I just added a 10.3” MK18 to my collection. I was a little worried about the differences and effectiveness, although my research (and this video) pointed me toward positive notions that it isn’t a terrible difference between them. Now I’m going plinking with all three of them!
It's amazing the sound of the shots when Paul's under that roof... the shockwave just *slamming* the sheet metal. So rad sounding :)
So yes there’s a difference but this shows that 10.5s still move metal fast enough to inflict serious damage.
Thats what i was thinking too. The velocity would also still penetrate light body armor meant to stop pistols.

I just bought a 20 inch barrel too. Feels bad man.
My big complaint with short 5.56 guns is the noise. The cartridge is just so damn loud out of anything less than the 14.5 inch guns.
Some people dont like that the 55gr fmj rounds are so close to the mythical "2700 fps" fragmentation threshold of the m193 load. Simple solution though, just use an expanding round
NOT AT ALL....... .223 IN ANY PLATFORM IS A FIREARM FOR CHILDREN
And Paul was able to manipulate the 10.5” faster” at 25 yards. So if you at the shorter ranges, home defense etc makes a good choice
His rundown of the meat target is like gospel at this point
Finally a religion I can get behind
@@archersparadoxx make sure the high-tech fleece bullet stop is in place before you go back there.
Another informative and well done comparison Paul! Makes me feel a lot better about my shorter ARs.
I always enjoy Paul's videos, he is a true professional and I always learn something...thanks Paul
I have that exact Ruger next to me right now and am very impressed to hear that it's putting out 2,800 fps.
I've got the 16". Fine rifle.
Yep, it's all about the ammo for that 2800fps. Switch to a BTHP or a heavier round, not 2800fps any more.
Yes another production thank you very much Mr. Harrell!
Like always, outstanding video!
So glad I came across this channel. Thank you Sir. Much appreciated
I would recommend replacing the Shasta with a beer or two, that way pork can go straight on the grill!😼 Kindest regards from Versailles,Kentucky!
My 10.5" ar is set up for home defense. I load it with soft points and it is amazing. Thanks for another great video.
Paul, you bring me such joy. Thank you.
Love the content as usual, and your camera really captures the beauty of your location!
Wow Paul at the 2:19 mark there was great deal of smoke from that under powered Federal XM193 giving only 2397 fps from the Rock River 16" barrel.
It was an error not a under powered round
Looked like oil contaminated powder, lots of smoke, not a lot of power.
@@jrowinski82 Watch again, that was no chrono error..
Was the round loaded with black powder?
Doesn't anybody hear what was said during the video. This was answered
In the redults aftet the shot string.
So much for comprehension.
This was an interesting video for me. I was debating on the barrel lengths for a new AR I want to build. Now I know, the 10.5" will do just fine!
It does, and I was surprised. still would be better to have a longer barrel if you want to go get medieval on deer or something for better shot placement at range
@No Nope If you want to avoid the tax stamp man. Have a 5.5 inch flash suppressor permanently affixed to it.
Paul.....you are the greatest, could sit and watch u all day, keep up the good work 👍🏻
Great video Paul. Keep up the good work!
For quite a while, I have been wondering about what kind of difference barrel length would have on terminal velocity, and accuracy. This was very interesting. Thank you for all your time and effort.
You can see, as evidenced by the additional smoke, when the 16" and 10" bbl rifles are fired. In comparison to the 20" bbl. That successively more unused pressurized gasses are escaping through muzzle. As well as, through the breach and gas tube, via the ejection port. However, the loss of velocity, and lesser accuracy performance at distance, are really a moot point. Given that the intended use of an extremely short bbl rifle is generally at near point blank range. During CQB applications, where combatants may be wearing body armor, as an example. Simply put, different rifles for different jobs.
*K Y* I agree ("different weapons for different jobs"), but I'll have to say the 10.5" barrel on that AR pistol did _way_ better than I expected against that 20" barrel. Feels like unless you are expecting to do most of your shooting out past a football field in length, the 10.5" barrel is a pretty good bet. I wouldn't have thought so prior to watching this video. 🤷♂️
The issue with this though is that if your AR is chambered in 5.56, it needs to go a certain velocity to cause an ideal wounding effect. I think its above 2600 feet per second? Once you cut your AR-15 barrel below 14" this effect gets lost due to not having enough time to speed up. Cannot remember his name but another youtuber went through Thunder Ranch and built an AR for that course. He was the one who explained how barrel length on an AR-15 can effect lethality.
With a loss of velocity down to an average of 2790 FPS from a 10” barrel, that 5.56 round is still moving fast enough... to at least 50 meters. Shot placement always overcomes ballistic limitations.
Of course one thing I didn’t hear Paul mention in this video is that when you shorten the barrel on the AR, the noise level to the shooter and those around him increases significantly. ✌🏽
Love your comparisons. Straight to the point.
