It would be nice to see the parts up close up .
Thank you for commenting Mark, I will certainly work on that for our upcoming videos.
Hey mark, here's our updated video!

@@midwestgunworks thank you
Ditto his comment about close up demo
@@midwestgunworks and you fucked it up again. Impressive.
After watching this im feeling a lot more confident in my first build. Just bought a lower from psa for black Friday and am getting a rifle kit soon, I didn't want to buy a full rifle as I felt building my first one would give me much more value financially and sentimentally. I'm very excited to finish it up!
How far along are you?
@@wizdumb_and_valor I have a stripped lower and bought a psa rifle kit I have it all and will be putting it together with my friend and his dad who both have way more experience than me in 3 days. I'm super excited but I wanted to make sure it was done properly and my friends actually have a decent collection of tools that'll make things way easier
Let me know how it holds up, I’ve been thinking about building a rifle from PSA
@@jacobseraphin685 when we got it built there was something wrong with the trigger, for whatever reason it was having trouble resetting as when we got it all put together and took it to the range after each shot I had to push the trigger forward and it'd click then I could shoot again, but it was entirely a trigger issue. It was what they called the PSA enhanced polished trigger. Everything else was good, it has a little bit of rattle to it and to fix the issue my buddy who helped me build it had his own PSA rifle that he'd built previously and he had just upgraded his Trigger to a geissele one so he gave me his psa factory trigger and now no more issues! I'm sure if I emailed PSA they likely would have sent me a new Trigger but I didn't want to wait as I'm very impatient lol. Rifle has been running like a charm since!
Probably hardest thing for new builders is knowing what spring goes where. Maybe show it next time 🤙
Here's our updated video!

You took the lower out of frame at the moments we needed to see it
We appreciate all of the constructive criticism. I must have assumed talking, and showing the install from the outside would be enough to help. In the future, I will focus on showing the parts being installed in depth. Hope you all check back, as our videos will continue to improve! Thank you again!
Look forward to it, but heads up, corporate media outlets have been pestering youtube about firearm assembly videos, taking out several belonging to the most notable members in the 80% community. On top of uploading these videos, I suggest having MP4 files as backup, and letting people know where they can download them since corporations and the media will step on both the 1st and 2nd amendment for their anti gun agenda.
Also you could do well to send that Wheeler AR tool back to Mr. Potterfield 😂
All joking aside I’ve found it was pretty poor quality and did not fit the castle nuts well enough to cause marring.
What...you mean a group of people offered constructive criticism in respectfully manner and recipient of said advise didn't take offense and then actual implemented said improvements with new video???? Who knew that folks could actually be civil.
THANK YOU VERY MUCH!!!! I was just fiddling with my rifle and i was curious of what i could do with the stock of my AR556 and i ended up launching just about every part of the stock assembly and i tried to put it all back together and i tried to rack it and the bolt got hung up on something. This video really helped me!!! Turns out i just needed to keep turning the stock so it caught the buffer retainer. Thank you so much!!
@@imagohouse7412 An armed society is a polite and tacticool society.
I’m glad there’s other videos on this process
This was great but I had to pause on every assemble photo and try and decipher just how things went, the trickiest for me to see was the hammer spring. I ended up grabbing another lower from a pre-built and using it as a guide with your video.
Would be really cool if you actually stayed in the camera frame when you were trying to demonstrate how to put pieces on
It had been several years since I'd last assembled a Lower, and your video was exactly what I needed as a refresher. Once I had it most of the way done, i didnt finish your video and went from muscle memory and denomination.. however, I did end up ejecting the buffer retainer spring and pin, probably because I didn't follow your tip (if any) to keep it from happening; as I'm in my garage, the spring is absolutely in the Nether Realm with all the left-footed socks the dryer eats. I did find the pin, however.
My 2 cents to add to the conversation? Watch this video twice before touching your parts kit. Remember that you can zoom with the new TH-cam update, it might help with close up shots.
Also know that the spring from a click pen works fine as a temporary replacement for a buffer retention spring. 😉
I just want you to know, I took apart my rifle for the first time to clean it, and couldn't figure out why I had a dead trigger afterwards. With this video and you showing how to put that lower assembly back together my trigger clicks and resets like before!! thank you for this video you saved me time and money taking it somewhere.
This video is made for someone who already knows how to assemble this gun.
I purchased one of the APF Lower & Parts kit last Friday. Very nice billet, and it has the anti-play set.screw adjustment feature for reducing any play between the lower and upper. Though the APF lower has an built in trigger guard, my kit came with a billet aluminum trigger guard assembly parts kit anyway....thanks!
Do you have a link, or part number for your lower? I'm ordering things now for my ar build, and once it's all put together I don't want the lower and upper to be loose and rattley. Appreciate it!
When I put together my first AR-15 lower I didn't have any of the special tools that make the job go so fast and easy. So I had to stop, think and improvise during the entire assembly.
BUT....... It was a learning experience, I learned a lot about the rifle and had fun too. Now, at the range, many neophytes admire my rifle and ask if I could advide them on their own project!
Good Luck!
Never have tried this before and using this video made it very easy. Great video.
I liked hitting the fast-forward button repeatedly and watching the pieces on the table rapidly disappear. I also like turtles.
Love the name of the channel!!!
Just built my first AR using a kit from palmetto arms. It was a great experience thanks to this video!!!
Thought this video would be perfect to follow step by step. Guess i was wrong.
This was a great tutorial. Thank you!
I've never staked a castle nut. It would've been cool to see what you did instead of the back of your left hand.
As someone who is looking to do an AR build at some point, this is very helpful. Thanks!
Put the mag release in before you put the bolt release in on the front takedown pin use an Allen wrench through the holes.
Hey thanks for showing the damn parts instead of just assembly really freaking helpful
I had to go backwards and remove the stock because you skipped the part where you show the pin that holds back the buffer tube. The rest of the video was pretty good. Thanks for the free tutorial.
Thanks for the walkthrough, was very informative. Ya, there's a few parts that are hard to see or get walked out of frame, but pay attention and listen well and this will get you through it just fine
Nice camera work
Very helpful. Was my first lower build. Thanks
Very informative. I have been both active duty military and law enforcement for a total of 15 years now. I’ve built and used AR’s in all environments. I have never staked my castle nut. Me personally have never had any issues of it backing itself off. Idk why, not saying it doesn’t happen. I know people that swear by it.
Just finished my first one thanks to this video. Thank you!
Honestly can’t believe one can actually do this I’m an truly astonished
thanks for convincing me to buy a drop in trigger
I love that the only part that is considered a gun is the stripped lower receiver
Awesome thank you, can 't wait until I can do mine.
This video was so awesome! Thank you for making this!!
oh man!!!! thank you so so so much. This is my first time and I was able to put everything together easily. I did shot some springs but your tricks helped out. Thanks again
"I am going to show you how to stake the castle nut" proceeds to block the camera and never show a single thing. Awesome. Very helpful
Good video, built my first lower after watching this once. Video'd the assembly will post soon and credit your video in the description.
Thank you, you've been very helpful. The trick for the take down pin ! nice !
Looks easy . Thanks for the DIY !
I never stake my castle nuts, just a little blue lock tight and tighten it up good with the spanner wrench, I've never had any issues with the castle nut backing off.
That's what I was about to say. About stakeing the castle nut. I never had a castle nut come losses. Im on my 4th build.
Big help as always thank you 😁👍
For pivot pin I use one of my large punches just as you do, however I use mechanic tweezers to hold the detent and a small punch to move the detent through the tweezers until I can work the punch to hold the detent. Then take pivot pin notch 25deg from detent to push the punch and once pivot pin through the first hole of pivot I rotate the pivot pin to lock the detent into the channel. Now I have a cheap harbor freight punch set, and a complete roll pin punch set with starter roll pin punches as well.
For bolt catch with drift pin I use a starter punch and a harbor freight punch to strike the starter roll pin punch which virtually eliminates the risk to damage the receiver. To finish the roll pin is where you risk scratching the receiver. Tape is best (spring loaded punch ALTHOUGH VERY GOOD TO PROTECT FINISH MUSHROOMS THE ROLL PIN DO NOT USE IF YOU INTEND TO REMOVE ROLL PIN!)
Pistol grip if using Phillips screw I use tape to hold screw to screwdriver to get started. Once started remove tape with needle nose pliers or mechanics tweezers, I also like to cock the hammer and place selector in safe before installing grip as rare if using 45/60/90 adjustable ambi selectors the selector can be easily installed wrong thus requiring removal of grip to fix selector.
For mag release I a unused pencil to push the button so mage release latch gets flush to push button then clock as necessary ( I like to test with a PMAG as I discovered RRA lowers are tighter and generally don’t drop unmodified PMAGs not even gen3 but will drop USGI mags ) testing with mag at this stage also tests bolt catch to ensure it is moving up and not preventing mag from fully seating. Yes if mag release is to tight you can actually pull magazines out if to loose magazine will not insert.
Great job, thank you
Here's an install video where i hide everything i do with my hands or off camera.
that was wonderful..... ready to try it myself now
Nice video Thanks it really helped
Timney AR triggers are $150. My total build cost right now is $340. We have different opinions on what is affordable.
great video ive used it multiple times now i always forgot one of the orientations
Great video but need to do more closes up , you lose us when you install parts from 3 feet away
Thanks so much great video!!
Done. Thank you so much.
Lol, first vid in my search results and you have the exact receiver I do
It would be nice if you would assemble this on the screen where we can see. Going to find another video!
3:12 he starts rhyming lol, love the video!!
Another tip for your next video, please show the punch during staking.
Very helpful information, but the buffer spring detent wasn't covered. It was smooth sailing for me up until the very end. Had to remove the buffer tube and install the detent, then I screwed the buffer tube in too far causing the tube to hit the upper receiver.
He did all the trickiest parts while holding it in front of his face off camera.
I would be assuming the rear take down pin would be the same as the front but it would have been nice to see if it isn’t. Doing my first lower assembly soon.
They isually look exactly the same but the fromt pin is flat slightly. The back one is completely round
The back pin being round wont fit in the spot the front one will fit into. Becaide it has th3 flat cutout
Yup, forgot rear take down 📌 ...
This is the fourth lower assembly vid which have been very helpful ...now for the but. no close up of trigger assembly. I guess it must be intuitive or I hope so.
Does install tutorial.... half of it is off camera. 10/10
by far the best lower assembly ive seen, the only one that shows how to install a mill spec trigger. Ive always had my friend do trigger jobs for me on mill spec triggers and ive found them to be as good as the timney and geissele triggers with polishing and better springs its far more affordable if its worth your time. I appreciate how in depth this video is and recommend it to anyone building there first AR15 thank you mid west gun works
With detents... do the nipple end of them go or connect to spring or springs ??? Like in the safety detent and spring in the grip..?
Here, let me show you this fine technical detail from across the room. Wow thanks guy, much helpful
Here's an updated video
th-cam.com/video/pGPHgkH96NI/w-d-xo.html
It’d be nice to see what parts you’re placing in & how
Thank you!
I like the AR-15 cause it reminds me of an airplane
Good video, but I need a closer zoom in, I'm a first timer and I'm hoping I can Identify the correct springs and other parts.
Nice!
The camera is too far away. A lot of your install is "off" camera. :(. Other than that I like your video. Thank you for making it simple
Ahh yes on to find a more helpful video
Ibmust be the luckiest person ever. As soon as I got my parts kit I felt like the detents were looking at me. Challenge accepted. First one flew out and stuck into the paint on my wall 😂 after that I got both in without a problem
Great info, but a zoom in a better camera view would be more helpful
I missed something, what keeps the buffer spring in, mine just wants to push out and hit the trigger
There’s also a tool that makes installing the front takedown pin a lot easier 🤷♂️
Love the camera angles It’s like he’s hiding the process
The video was well done but I agree with some of the comments below that maybe a close up would help people like me who are interested in building their first rifle.
Did you do the rear take down pin? I understand it's the same as the front... but I don't recall it being in the video
I mean... No close ups on anything huh?
On the buffer I noticed that the castle nut was already on there after I screwed it all the way down, you might mention that you screw it on first.
wish you'd lower the assembly as youre doing a lot outside of frame. thank you none the less!
Assembling my first AR and following your steps. Now my safety dont clear the trigger assembly and i have to disassemble...
90% of what needs to be "done right" is off screen or a mile away.
Thanks for saving me time
It's easier if you do the bolt release second. You didn't mention putting a spring follower (pin) on the bolt release spring.
it's a piece of cake.
Gives me ideas regarding my lower
Use a penny taped to your finger to put small pins and detents in place :)
Having a screw instead of a roll pin for the bolt catch would have saved me about 45 minutes of assembly time, heh. Unfortunately, both my stripped lowers came with the roll pin type. Other than the pivot pin, everything else is pretty easy to install. Real Avid sells a tool that makes the pivot pin a snap without having to worry about shooting the spring and detent into another dimension. Just how important is staking the castle nut? I didn't use Loc Tite, just cranked it down as much as I could with a wrench and haven't staked it. Oh, one other thing that is of medium difficulty is installing the trigger guard. I noticed your lower came with the trigger guard already installed or manufactured as part of the lower receiver. That feature would have saved me another 30 minutes. The PSA lowers I have purchased require a screw and roll pin to install the trigger guard. Yeah, I'm slow, but I'm old.
Didn’t show any of the small and easily confused springs up close….. thanks guy
Should show up close. This was like a race.
Here's our more in depth, updated video
th-cam.com/video/pGPHgkH96NI/w-d-xo.html
Is the safty only supposed to move when the trigger is cocked only? I am assuming that its supposed to work when its not cocked as well?
How do you get the buffer soring to stay in the buffer tube like that?
something else to include. i noticed extra parts when i was done, and it makes sense, if you didn't buy the lower, you wouldnt have the pin and screw for the bolt catch
The explanation of what you were doing was helpful but, you kept moving out of the camera frame so we could not see what you were doing. Also when you were in the frame your hands were too far away from the camera to clearly see what you were doing. Helpful for sure but I’ll see if I get mine put together. Good try, thank you!
This video is decent for someone who just needs a refresher but for someone brand new it’s useless. You should remake it showing close up of how everything goes.
what is the different between full auto and semi auto . is it in the thrigger or safety botton?
Thanks
Question ? What is needed to change a AR 22 caliber to a 556 round?
Please make a upper assembly video with tool recommendations 🙏
Would be nice to have a close up of the AR-15. Its hard to know what is what to be honest. Nice to have a video at the very please.
Taparoo 👍
Get any further away from the camera?
I wish you had a camera view that was extremely close up. I simply couldn't see what he was doing and I would NOT be comfortable attempting a build with just this video. Some TH-cam'rs have a quality camera over their work station that looks straight down on what the hands are doing with the parts. Perhaps if you look at some "How to build a drone from scratch" these would be excellent examples of how this camera technique is executed. Very best regards.. Z :)
