I think you flipped the description for adjusting the sights, if you raise the front post, your shots should go down, and if you lower it the shots should go up… you said it right a couple times but in your “Pencil” demo, you said it backwards
There is an arrow on the front sight that says 'up' which is to raise the point of impact. So if you are shooting low, turn it in the direction that says 'up'. Opposite direction if shooting high.
yes. backwards. raising front post will send barrel down when lining sights up. I alway encourage people to look at it in the extreme . if you added 3 inches of post hight the barrel would point at the dirt when aligning sights. .
Finally someone who titles a video install of the sights and actually shows the actual process of installing it! Bizarre how many people title their videos about the sights and adding them to a rifle but all they do is yack and dont even show the actual process clearly or at all. Thank you!
Sight radius was the word you were looking for when talking bout the distance between the sights. Longer sight radius helps for making shots further away and still functions for close up, shorter radius helps for getting sight picture faster, pretty sure you knew that already though just describing for anyone curious.
I’m definitely curious as I’ve always used iron sights or scopes. Is there a right or wrong distance for the sights to be apart? Meaning should they at least be like 12” apart or something?
I have a very long central hallway -- about 25 meters -- and use it to set an initial zero with newly installed sights/optics for with an LED boresight. Saves some time fussing around with ammo on a range. No LED boresight is perfect, but it gets you close enough to finish zeroing quickly on a 25 meter range. With an AR-15, you only need to work with the upper when bore sighting it. I recommend temporarily removing the extractor from the bolt when using a boresight and using the bolt with BCG to hold the boresight in place in the chamber. Removing the extractor while doing it prevents damage the boresight case rim which is typically soft metal.
I just bought a pair of the MBUS sights, and all your comments were very helpful, especially about the tightness in putting them on the rail. I used a few drops of CLP to ease them on, with a few taps of small hammer. The double rear sights were so tight, I couldn't separate them with a thumb nail but used a small screw driver; a nuisance. Thanks, too, for the sighting comments.
I’m so glad I went to TH-cam!! I nearly hammered the thing onto the rail top-down... sliding it is the trick to get it on. I think I would’ve broke something
Thank you for this vid. I bought the same sights, thought they were borked, but after watching this and reading comments, I was able to install after adding some rem oil to the sights and my rail. You all rock! 🤘
Just ordered my Magpul sights for my Saint Victor AR15. I’m hoping I can install & get them sighted in correctly all by myself. Thank you for the tutorial. 🙂
I see you made this video about 8 months ago and had very tight sights. I just installed about my 10th set of Magpul sights and they were extremely tight to mount on the rail. I never had this issue before either. At first I thought the sights or the rail was defective. I guess it's a good thing because once it is mounted you almost don't need the screw, lol. Magpul must have tightened up their tolerances a little bit, it will probably be better in the long run. Magpul sights are solid sights for the money.
The easiest way is to keep in mind the directions on the sight refer to the bullet impact point. ie.. if you are low and the arrow on the sight says “⬅️ up “you turn the sight clockwise to raise the point of impact. Same for L/R, if the arrow says “ R ➡️ “ and your hitting right you turn the back sight adjustment counter clockwise to move the impact point left . This applies to all sights.
Thanks for the clear instructions on installing these sights. On another note, I think you sound just like Judge Reinhold, 1 of the leading actors on 'Ruthless People' (1986 movie). You have an excellent voice. Have a great day:)
@@EagleRun23 He was the Younger Cop in Beverly Hills Cop. I think they called him Billy. You'll sound alike. Great video just picked up a pair of these two.
The little wingnut tool it comes with to adjust the sights can be used in place of a flathead screwdriver to tighten the sights on the picatinny rail. You can tell since there's a little section of it that's thinner that fits just right in it.
Read the instructions closely and followed your video which was emensly helpful. Had to tap lightly with a rubber mallet front and rear sights. Thank you!
My magpul sights are tight on the rails also. I also went to adjust the rear sight and the knob popped off and the small indent bearing went flying! The roll pin was missing, made a new one for it. Ended up not using them because the rear sight interfered with my 1x6 scope. The riser on my scope is perfect for co-witnessing flip ups but can't get it far enough back for eye box on scope.
I dot front site with bright orange nail polish. Small drop. I cut small peep of rear for center mass. If need more, get out sniper.... Thanks Bud for the help
Excellent video thank you very much for posting. I'm an amateur and I really appreciate these videos. So thank you again for posting, very helpful for me.
Easiest way to think about it is which direction does the round need to go. Shot is high you adjust down, shot is right you bring it left. Same for scopes and dots.
yes sir! correct. Never meant for the video to get so much views. I am always learning how best to do stuff and explain stuff. I def mixed up a few statements but my illustration was correct, haha
But that's contradicting what other people are saying about the FORS acronym. FORS method means if you need to take your shots down you would adjust the front sight post up, I'm confused?
@@alexmundy9932Lowering the front sight makes you bring the butt of the rifle down to get the sights lined up. Which means the next round will impact higher.
Thank you so much! This was very instructive. This is a new platform for me and the Magpul back up sights fit very tightly. Good thing I have that great little gunsmithing hammer with the nylon and rubber heads.
I got these for my Ruger PC carbine and unfortunately the chassis beneath the back rail is too shallow for the “flip-up” mechanism to work. The leaver hits the chassis. It’s too bad because I love these sights.
Ive aleays been taught to put the front peg on the target, not under it, is that just this sight that is different, or are there just different ways to use iron sights?
I installed my front sight backwards so I don't have to see the ugly backside of it and it works just great, just in case anyone else didn't like seeing the ugly backside of the sight. Highly suggested
The idea of folding to the rear is because your gun is always faced and maneuvered forward, walking, running, poking your barrel forward through brush hitting a branch or bashing and breaking a glass window etc you want your sight to fold rather than break , especially a polymer one , they get somewhat brittle if super cold . Stressing metal sights mounted backwards can end up tweaking the hinge pin assembly so they get loose and sloppy or dont close all the way
I also installed mine backward but for the reason it makes more sense that the button is behind the sight. Makes it easier and faster to activate the switch. With it installed “correctly” you have to make sure your thumb is in front of the sight when you hit the switch, then move your your hand back to where you normally grip.
Thank you for the instructions. I will note this though: I used the mbus pro sights. The front sight post was labeled up. Following the "front sight is opposite" saying, I went "down." After two sets of three rounds I realized the sight had that already taken into account. Lol
You are tapping the optics towards the front of the rail. Shouldn’t you tap them towards the back so that way recoil will only reinforce their position? That’s what I’ve read on optics anyway so I would imagine it would be the same for iron sights.
its in a rail slot and on there super tight. I would have had to tap it 14" all the way back down from the other side, that would have been sketchy! haha
@@EagleRun23 lol I didn’t mean other side of the gun. I meant while the screws are in and inside the rail. While the optic is loose tap it to the rear (inside the rail) so the recoil can only reinforce the position. After that you use Loctite or whatever. It’s probably just a bigger issue when you have a 6X or so because the slightest change will be magnified. I remember looking it up when I put on my Primary Arms Raptor 1-6 . There’s a little back and forth in rails themselves. Again probably not an issue with iron sights. I still tapped them towards the back anyway… lol
There’s a reasonably priced laser boresighter (made by Bushnell I think). Instead of slipping it into the chamber end of the barrel, you insert it into the muzzle. It comes with several interchangeable tips (or bushings) for fit in a range of different calibers. I’ve used one for years. I set up an aiming point on living room wall (masking tape with Sharpie cross marking) and set rifle on gun vise on dining room table. Adjust sights or scope to align with the laser dot on the tape. Then at the range, at 50 yd I’m always on paper, can fine tune it from there. If you want to do this outside at a greater distance than the length of a living room, you can get it more precise, within just a couple of inches, before you ever use a single round of ammo.
I ran into the same issue when installing mine on my handguard (Aim Sports Wraith). I ended up using the rubber mallet that came with my roll punch kit to tap it on.
The stuff on the end of the screw is called "microencapsulation" .. it's basically dry powdered loctite/thread locker.. in automotive they say so replace these screws every time as if the stuff is one time use... Idk you could surely just put a drop on if you're worried about it coming loose
Theoretically and some rigs have gas blocks with pic rails. They really get hot. Handguards not so much. You would have to intentionally be doing some sort of burn down or ww3 for it to be a concern in my opinion :)
The problem with these split rail sights is that the rail is in two pieces! Micro differences between the front and rear rails and sights! Plus, they are composite, giving a little! I've noticed my mono rail 22lr and 12 ga have very tight shot groups! On to something? No split rail, plus they are Alum., all metal. Mabey take down pins for split rail ar's need a tighter tolerance? Bandaid? Thread tape? Scotch Tape? I would love to figure out my S&W 15-22 accuracy problem, Any Ideas? MBUS worked great for first 100 rounds or so, then couldn't hit anything! Mabey loose barrel? Any comments will be greatly appreciated.
I think that's definitely something to keep in mind when dialing in sights. especially if the front sight base is just a few spots of picatinny on top of the gas block with no floating barrel. shooting past 100 yards with that could certainly lead to inaccuracy.
I have not tried it at the range yet, using a magnetic laser bore sighting tool I wound up with my rear sight almost all the way left and my front sight almost all the way down. I'm wondering, could my set of sights be defective, or are these extreme settings sometimes required with MBUS sights? I don't recall ever needing such extreme adjustments on an M16.
I’m curious what the outcome of your sighting problem was. I’m having the same issue. My front site is all the way down and I’m still shooting low. Any suggestions?
@@chuckcunningham9979 Not resolved. The range near me that can accommodate rifles has been closed for the last several months, so I've had non opportunity to sight the weapon in for real.
@@rangersmith4652 - Thanks for responding. I’m probably going to take the sights off and try re-installation. If that doesn’t work, I’ll just take them off and stick to my scope. Thanks again.
Just got my magpul sights in...I can't fit them over multiple rails. The rear sight stops before it even reaches the first rail slot, let alone the second slot. It seems as if I have to take a dremel tool to widen the seating portion of the sights. This is ridiculous. Fyi...both are Midwest Industries rails. I do not have a teflon hammer nor a hair dryer to warm it up.
Magpul uses a high grade of polymer. Not going to harm them with lite hammer taps. If you don’t have a nylon face hammer, use a regular hammer and put a small block of wood against sight to hit on.
I’ve put mine at the first rear notch above the charging handle. I haven’t test it out yet obviously with the ammo drought. But if anyone could answer this is this a secure spot to leave the rear sight.
So weird I was at the range adjusting my exact sights and mine was hitting low so I took my tool turn it in the direction of up after about 5 adjustments up my bullets are landing right next to the bullseye a tad off to the right so now gotta adjust my rear
@@burntdog8277 yeah that can be frustrating especially if you’re trying to zero it through ball and self defense ammo. If I can get some self defense ammo I’m going to zero it for 25 yards and leave it at that.
I think you said it backwards. If you raise the front post, you will lower the point of impact. If you lower the front post, you will raise the point of impact. In your example, you were shooting high. Therefore, you would need to raise the front post. The way I understood you to say it was backwards.
I noticed the same thing when I watched this video. You are right Bill. EagleRun may have been thinking in terms of the barrel perspective and not the sight perspective. I'm surprised I had to read this far down to find someone who was paying attention.
@@cakalackybilly1286 what was funny about it was that he was saying that it was backwards to what you would normally think and to make sure to do it the right way. Then he describes how to do it...the wrong way...LOL
So ive installed my rear sight with no problem and i got the front one on with no problem but when i try to pop up my front sight it wont pop up. When i take it off the rail it pops up. What do i do?
The Magpul’s are a bit low you may want to look at some of the true iron sites that are made of metal I believe the troy industries and the Midwest industries are a little taller I don’t have measurements to confirm that
you have it backwards! If you're shots are high, you raise the front sight post, not lower it. This is the problem with youtube... Anyone can act like an expert even when you don't know what you're doing!
I said it correctly. I have done it for 20 years and taught dozens of people how. The perspective is if you are raising the post or raising the shot. Easy to slip up that’s why I used the pen to illustrate.
@@EagleRun23 Never have I raised my front post and had my next shot go higher, and that’s exactly what you said will happen @ 10:56, and you were using your pen to illustrate it incorrectly.
A complete upper from a major manufacturer came with a Magpul rear sight. It's an unadulterated JUNK POS. I installed it, played with its chintzy mechanism a couple times, promptly ripped it off, smashed it with a ballpeen hammer to prevent any reuse by anyone, and pitched it into the trash bin. It had no repeatability whatsoever when flipped up, and its flimsy construction would obviously soon break off under field use. There is no comparison between this rubbish and the KAC made for the USMC, or the (less expensive) Troy Industries, also made for U.S. Government procurement. As to sight adjustment, the video does well in describing how to which way to move a front post and rear aperture to zero a rifle with iron sights.
Magpul has always been good for me. BUT there are cheap Chinese magpul COPIES out there. I bought a couple once online. The logo is close but not exact, the quality is not even close!!
So glad i saw all of you having issues with the tightness of sights i painted my ar multicam and used multiple layers of paint so yeah it was a BITCH. Had to re touch it after
Mine were tight , on an Aero Precision AR9 build. I expect to use this build at less than 50 yards. I like these sites and chuckled at the packaging that stated they were made for 5.56 . I am using them for a 9mm .
Just a heads up, the front sight zero tool has a groove on the top to tighten the screw on the sights. No need for a screw driver. Also, install the front sight by sliding it TOWARDS the barrel tip. Not from the tip back.
Does this mean you can only use iron sights? We can't add like a reflex sight also? If it's to small what can we do to have iron sights and relex sight?
@@Not_Sure_81 I got me a Feyachi RS-28 4 in 1 Reflex Sight and also the OTW Flip Up Iron Sights Flip Up Front Sight + Back Up Rear Sight. I noticed my front iron sight you can look through the reflex sight, so is that the correct way to use if the reflex sight would happen to go out?
@@thebestofthebestsir47 I keep mine specifically for a reserve. Most of us only use the red dot and keep the backups folded and out of view. It is of course user preference. Try shooting with and without the sight up. Whatever works best for you is the way to go. Also pick your preferred red dot height. There's lower 1/3rd and there's absolute co-witness. I prefer absolute. There's a ton of reddit posts and TH-cam videos on this. Again though, in the end, it's all about what works best for you

FORS…..front opposite, rear same. A good crutch to remember sight adjustment.
The bigger/smaller aperture hole is for night and day shooting. Smaller hole, smaller pupil for days. Larger hole, larger pupil for night shooting.
Also larger hole for up close
Follow the grouping. If you're hitting High move the front sight up if your hitting low move the front sight down
Another way of saying it is------- Up is down and down is up.
Sight radius was the word you were looking for when talking bout the distance between the sights. Longer sight radius helps for making shots further away and still functions for close up, shorter radius helps for getting sight picture faster, pretty sure you knew that already though just describing for anyone curious.

How much does it change the POI for each click of the front post?

Lower the post raises the barrel a guy taught me.
I have not tried it at the range yet, using a magnetic laser bore sighting tool I wound up with my rear sight almost all the way left and my front sight almost all the way down. I'm wondering, could my set of sights be defective, or are these extreme settings sometimes required with MBUS sights? I don't recall ever needing such extreme adjustments on an M16.
When they aren’t lined up straight but the shoot straight that makes me frustrated.
I’m curious what the outcome of your sighting problem was. I’m having the same issue. My front site is all the way down and I’m still shooting low. Any suggestions?
@@chuckcunningham9979 Not resolved. The range near me that can accommodate rifles has been closed for the last several months, so I've had non opportunity to sight the weapon in for real.
@@rangersmith4652 - Thanks for responding. I’m probably going to take the sights off and try re-installation. If that doesn’t work, I’ll just take them off and stick to my scope.
Thanks again.
If i get my sights zeroed and then I move the sight back on the rail towards the charging handle will I loose zero?
yes, also you want the longest sight distance, ideally. wont change much though, especially if you chose like a 25y zero or something closer
If I raise the front of my barrel the round impacts lower? Something doesn’t sound right.
its possible I I stated it incorrectly one time but the video and the visuals are correct.
With boardsides eliminate how we're going to the range?
What kind of rail is that?
This is a palmetto upper. Assembled this one for my father. She runs great.
@@EagleRun23 Thanks! I just built one and test fired it a couple of days ago
Just got my magpul sights in...I can't fit them over multiple rails. The rear sight stops before it even reaches the first rail slot, let alone the second slot. It seems as if I have to take a dremel tool to widen the seating portion of the sights. This is ridiculous.
Fyi...both are Midwest Industries rails. I do not have a teflon hammer nor a hair dryer to warm it up.
People in comments gave me crap for tapping them in with a nylon hammer. But it work and there was no damage. Do what you gotta do :)
Magpul uses a high grade of polymer. Not going to harm them with lite hammer taps. If you don’t have a nylon face hammer, use a regular hammer and put a small block of wood against sight to hit on.
I’ve put mine at the first rear notch above the charging handle. I haven’t test it out yet obviously with the ammo drought. But if anyone could answer this is this a secure spot to leave the rear sight.
try it, if its in the slot, its secure!
@@EagleRun23 definitely and thank you so much for the reply. 😎👍💯🇺🇸
So weird I was at the range adjusting my exact sights and mine was hitting low so I took my tool turn it in the direction of up after about 5 adjustments up my bullets are landing right next to the bullseye a tad off to the right so now gotta adjust my rear
@@burntdog8277 yeah that can be frustrating especially if you’re trying to zero it through ball and self defense ammo. If I can get some self defense ammo I’m going to zero it for 25 yards and leave it at that.
@@totalnewb123 yupp I was at 25 yds too
I think you said it backwards. If you raise the front post, you will lower the point of impact. If you lower the front post, you will raise the point of impact. In your example, you were shooting high. Therefore, you would need to raise the front post. The way I understood you to say it was backwards.
I noticed the same thing when I watched this video. You are right Bill. EagleRun may have been thinking in terms of the barrel perspective and not the sight perspective. I'm surprised I had to read this far down to find someone who was paying attention.
@@cakalackybilly1286 what was funny about it was that he was saying that it was backwards to what you would normally think and to make sure to do it the right way. Then he describes how to do it...the wrong way...LOL
Great video on install and adjustment/zeroing instructions, I knew what you meant
So ive installed my rear sight with no problem and i got the front one on with no problem but when i try to pop up my front sight it wont pop up. When i take it off the rail it pops up. What do i do?
Sounds like the screw is too tight on the rail.
Thank you so much . For lesson. Perfect tutorial.
is it normal to have the backsight adjusted all the way to the left in order for the round to go where you want it to go when you line the sights up??
Happy i found this.
Mine came with an instruction QR codes that lead to nothing. I was like wtf is this key for. Lol.
So does anyone else have to press their cheek super deep into their stock to get a sight picture? It’s almost as if they’re too low for me. Any help?
The Magpul’s are a bit low you may want to look at some of the true iron sites that are made of metal I believe the troy industries and the Midwest industries are a little taller I don’t have measurements to confirm that
you have it backwards! If you're shots are high, you raise the front sight post, not lower it. This is the problem with youtube... Anyone can act like an expert even when you don't know what you're doing!
I said it correctly. I have done it for 20 years and taught dozens of people how. The perspective is if you are raising the post or raising the shot. Easy to slip up that’s why I used the pen to illustrate.
FORS
@@EagleRun23 Never have I raised my front post and had my next shot go higher, and that’s exactly what you said will happen @ 10:56, and you were using your pen to illustrate it incorrectly.
@@scottmorrow5497 sorry if I crossed you up. I just have mixed it up.
That's what I thought.
will the front sight work with the mbus pro rear sight?
I dont know for sure that I can say off hand. I would imagine so, and there is decent adjustability in that front post.
I just found this video after I cut my fingers on the rail trying to install the rear sight. It’s definitely a tight fit. 😂
I just made a new one with some AT3 pros. They aren’t that tight. :) welcome brother. Thanks for watching!
On one of mine the sights flip opposite directions, they give me the most distance on that particular weapon, I don't see a problem
A complete upper from a major manufacturer came with a Magpul rear sight. It's an unadulterated JUNK POS. I installed it, played with its chintzy mechanism a couple times, promptly ripped it off, smashed it with a ballpeen hammer to prevent any reuse by anyone, and pitched it into the trash bin. It had no repeatability whatsoever when flipped up, and its flimsy construction would obviously soon break off under field use. There is no comparison between this rubbish and the KAC made for the USMC, or the (less expensive) Troy Industries, also made for U.S. Government procurement. As to sight adjustment, the video does well in describing how to which way to move a front post and rear aperture to zero a rifle with iron sights.
Magpul has always been good for me. BUT there are cheap Chinese magpul COPIES out there. I bought a couple once online. The logo is close but not exact, the quality is not even close!!
@@mikewatkins7618 A major upper manufacturer isn't going to buy and install Chinesium Fakes. The chintzy cheap plastic Magpul are worthless JUNK!
The handle on the adjustment tool is meant for tightening the screw.
What brand AR is that?
@@Meadowsxl305 this was a PSA for my father I believe. Been a while since we made that one :)
@ thank you
The front sight picture you describe is commonly called " pumpkin on a fence post".
The adjustment is to move the group to where you aiming at. It's simpler to think that way
Looks like I've installed the front sight post backwards on 2 rifles in a row 😂😂😂😂 woooow. Thanks brother.
ohh no! haha
@EagleRun23 oh no is right. It was both sights. Lol, thank you for the video.
This was the info I was looking for thank you
Are you sure you mounted them correctly? I mounted mine with the Push Button in front not the back.
ya? i think so!
My front sight doesn’t sit as flat as yours does.
So glad i saw all of you having issues with the tightness of sights i painted my ar multicam and used multiple layers of paint so yeah it was a BITCH. Had to re touch it after
true
They are easier to install if you install them when they are already flipped up and in the ready position
My front sight is good with night but it seems like it’s more to the left I need more right .. help
Please start out by identifying that the area at the end of the barrel is the Front Sight location. The Rear Sight is the area closest to your face.
Ohh wow did I mess that up? Didn’t even catch that. Thanks for pointing that out.
How that Ballistol works for you?
What instructions? Mine didn't come with any.
Is this the same guy that does the 1st amendment audits!? Sounds just like his voice. Love that guy
haha, not me, i watch those , kinda fun i am not that provocative, haha they just make me mad sometimes!
Do you need blue loctight?
I wouldn’t but great reason to train and use it. If you do you could add.
Mine were tight , on an Aero Precision AR9 build. I expect to use this build at less than 50 yards. I like these sites and chuckled at the packaging that stated they were made for 5.56 . I am using them for a 9mm .
what do you think the plastic is going too break from shooting the gun? LOL
Great video. Was nervous to tap it w hammer but had to
I used this sight at 100 yards on keltec cmr-30 . Wow is it accurate. No need for a scope.
I just want to know each click Equals to what. Im using armo dynamic paper zeroing target and no clue what those numbers on the paper mean.
I don’t have the little tool thingy
amazon has them or you can borrow at a range
F.O.R.S
front opposite rear same
Just a heads up, the front sight zero tool has a groove on the top to tighten the screw on the sights. No need for a screw driver. Also, install the front sight by sliding it TOWARDS the barrel tip. Not from the tip back.
A small piece of tape (I use 3m painters blue) over the nut will hold it in place.
Does this mean you can only use iron sights? We can't add like a reflex sight also? If it's to small what can we do to have iron sights and relex sight?
Thats why these are called mbus sights. Magpul backup sights. Key word is backup. So of course, get a red dot. Red dot dies...use your backup sights
@@Not_Sure_81 I got me a Feyachi RS-28 4 in 1 Reflex Sight and also the OTW Flip Up Iron Sights Flip Up Front Sight + Back Up Rear Sight. I noticed my front iron sight you can look through the reflex sight, so is that the correct way to use if the reflex sight would happen to go out?
@@thebestofthebestsir47 I keep mine specifically for a reserve. Most of us only use the red dot and keep the backups folded and out of view. It is of course user preference. Try shooting with and without the sight up. Whatever works best for you is the way to go. Also pick your preferred red dot height. There's lower 1/3rd and there's absolute co-witness. I prefer absolute. There's a ton of reddit posts and TH-cam videos on this. Again though, in the end, it's all about what works best for you
@@Not_Sure_81 Awesome thanks for the response.
