How to Install AR15 Buffer Tube Assembly - Aero Precision Lower Receiver

[@willsatozlife4359]

I am old, I have arthritis and just assembled my first lower thanks to your videos. thank you.

[@edroz8919]

The light is so good that it helps a lot to understand the build process, thanks for the video series

[@1stShotTactical]

Thanks for the comment and support! Glad I could help!🙏🙏

[@r1dg3xrac3r]

This whole time I thought you had finger prints all over the lower, turns out they're camo patterned. I like it.

[@luketabayoyong3084]

Thanks for the tutorials bro helpful! In the process of building my first AR

This is a great video, good on keeping the object of the moment in the middle of the camera view, good explanations and tips, clear and simple instruction!!! A new subscriber is born! GLORIOUS!!!

[@PupsPistols]

Great video! All the info you need, nothing you don’t 😎👍🏻 Thank you sir!

[@hairydogstail]

Always put Aeroshell 64 grease on the threads before install.. Torque the castle nut to 38-40 foot pounds and stake in two spots..Best to use a jig or vice to keep the buffer tube (receiver extension) square to the receiver..

[@nicksanjay3902]

This.

[@jeffpraterJSF]

Just the buffer tube threads?

[@hairydogstail]

On the receiver extension threads (buffer tube) so the grease covers the threads for the receiver and castle nut..@@jeffpraterJSF

[@neftalynegron4219]

Why?

[@hairydogstail]

@@neftalynegron4219Because it stops the galvanic action between the aluminum and steel.. Lubing the buffer/castle nut/receiver threads to get proper torque..Dry threads give false torque numbers ..

[@misaroorasim]

I used this vid for my Gas blow back Airsoft rifle. Thanks 😅

[@jessvagnar4957]

Definitely hand tight is fine. I leveraged it with just my arms and it snipped a piece of the castle but off. Not a big deal practically but definitely knocked the color theme

[@exoticwhipsbroadspipesandbags]

Rip castle nut 🙏🏻

Thank you so much! These instructional videos are awesome. Great job!

Thanks for the comment and glad I could help!!🙌

[@rc54]

A little bit of BLUE Loctite is also very helpful.

[@notreallyme7465]

This was a fix for me. First build and I am highly trained by youtube. I followed a video and things went really good till the end. I did not understand the Buffer Tube and the detent pin. The video made out like the pin was to lock the Buffer Tube. While it does but that is not what it is for. It holds the buffer spring in. Anyway, my rifle did not want to close and would click if you pushed it down. the last 1/16 of an inch to lock. I watched this video, and your tube does not stick out at all. So, I backed mine off one turn and sure enough that was the problem. Thank you very much for this life saving video. There is a post saying the guy ground it off with a Dremel.

[@1stShotTactical]

Hey thanks for the comment! And I’m glad I could help!🙌🙌 congrats on the build and I hope it works well for ya!

[@SSQAC]

I'd like to see dremel guys builds

[@wlc1980]

NICE VIDEO! The video is well lit with great close ups, very good audio with very clear instructions. Unfortunately other channels are sometimes hard to follow with bad audio, dark lighting or the narrator assuming we know things. I'm enjoying my first AR15 build! Keep up the good work!!

[@taylorharbin3948]

Great tutorial. Looking forward to finishing my first build soon.

[@Heiryuu]

Thanks for this. The first build I ever did was for an BRN-180 so I didn’t need to do this part.

[@StratBurst92]

I admit that my staking jobs suck. Bought the Fortis self-retching end plate and no need for staking, Primary Weapons System also makes a similar product.

[@1stShotTactical]

Thanks for the comment and info! I might have to check that out!!!

[@countryboyzz8448]

Helped with installing my buffer tube on my m4 lower for my 50 beowolf I am building👍🏻

[@LadisMiranda-gb1jw]

Hello and thanks for the knowledge. I'm, excited to build my 1st AR. So I've been watching tons of videos to get the technical process down for build. If you have any advice I'm all ears. Thanks again.

[@badbattleaxe5832]

What about your takedown pin detent and spring? I did not see you install that.

[@bigcile]

I noticed as well. I'm currently doing my own build and am getting my stock/buffer tube ordered soon

[@wadeadkins5838]

What about the spring in the back ?

[@themightycrixus1131]

Nicee. Thanks for the video. I am building an M4E1 as well! Mine will be .300 blackout though. My first AR in 5.56 i bought already assembled. This M4E1 will be my first build. Still deciding how much of upper I am going to put together. I noticed just about all complete uppers rely on a set screwed gas block but i would like a pinned one. I lack a drill press to do it on my own though. Ballistic Advantage sells a barrel that has a pre-drilled gas block with a pin included but if I go that route I will have to buy everything separate... Aero doesn't sell just uppers with a handguard attached.

[@1stShotTactical]

Thanks for the comment! And you can buy complete uppers from Aero, check out the website AIMsurplus they have them. But I’m not sure if they have any in 300blackout so that might be an issue. Let me know how it goes!🙌

[@taylor315]

I’m running into the same thing. I got a Faxon barrel with no dimple but I’m going with the superlative arms gas block in a clamp style. The clamp styles with some blue loctite shouldn’t budge

[@themightycrixus1131]

@@taylor315 i found that Ballistic Advantage sells an enhanced(same as the M4E1) complete upper with the pinned gas block on their website. Aero gets all their parts from Ballistic Advantage so it will be the same except for logos. Its called the Hanson barrel. Check it out man. While I was at the range last time I got to a cumulative of about 800-900 rounds on my 5.56 the set screws came out of my gas block and the block worked loose making my AR a bolt action rifle. I don't want that to happen with my next rifle ever. Yes my barrel was dimpled too. I put new set screws in and loctited them after realigning the gas block. Not a great experience. That is not the type of malfunction you can fix in the field

[@JimmyCzerwinski-p4g]

You need the real avid mag that goes in a vice . Then you can really tighten castle nut .

[@bigmanduncan]

I need an honest opinion… HOW IMPORTANT IS STAKING??

[@1stShotTactical]

Lol it’s recommended but you could get away without doing it👍

[@chriscosby2459]

I don't like staking -- I use a little loctite.

[@SethW-w5x]

Absolutely Flawless

[@panic151]

On mine,I had to worry about the detent spring for the rear take down pin, I guess on this lower, it's different?

[@ACP-GC]

This guy did great except when he was talking about tightening the castle nut

[@johny9516]

Great instructional video…but what about installing the rear takedown pin spring and detent?

[@qckhnda2000]

That lower has a threaded plug that holds the rear take down detent pin/spring in. He installed it in the first video.

[@chainlandproductions820]

@@qckhnda2000 Well he should of said that.

[@chainlandproductions820]

@@qckhnda2000 for those of us that just come across a random video

[@DemonGunWorks44]

U should lube ur buffer spring and buffer weight as well add some thread locker

[@1stShotTactical]

Yes that’s a great idea!!!! Thanks for the comment!

[@chuckkolancz4969]

That grip is horrendous, but I respect the aero build

[@1stShotTactical]

🙌🏻🙏

[@MegaGman83]

Question. Great video series it has helped me along with my Aero build. When installing the buffer tube should there be any blue threadlocker or oil/grease on the threads before torquing down?

[@hisreign4me]

You completely skipped the little spring on the back of the lower that’s located behind the retaining plate.

[@hisreign4me]

Why? Isn’t that an important spring? I thought all lowers had that spring.

[@deoxribonucleicacid8746]

​@@hisreign4me apparently it's not used on this lower. If you look it pops up on the screen. Yes that spring is important, it holds the detent for rear takedown pin.

[@qckhnda2000]

No he didn't. Watch the first video.

[@trailheadmedia5578]

It’s because he’s using the Aero lower parts kit that comes with the threaded 3/32” allen spring retainer. He installed it in a previous video covering the lower parts kit.

[@qcn99]

he literally has a big red box stating this.

[@mick5740]

Am I missing something or did you not show and explain installing the springs and detents lol

[@tommyshearer891]

Nice braugh

Thank you.

[@brianjadlowiec9068]

I was looking for a trick to get the rear pin spring in without bending it. You didn't reinstall it. No trick here.

[@JimmyCzerwinski-p4g]

You need the mag that can be put in a vice

[@dudechain]

Buy a 30 dollar lower vise block. Makes maintenance easier

[@discofishing]

So you left out the spring for the rear take-down pin. Why?

[@johnny-smith]

Aero lower has a special install. See his other video

[@1stShotTactical]

That’s in the other build video I made in this series!!🙌🙌

[@Vitone22]

Sorry for my ignorance, on a regular AR15 mil spec build 16 inc barrel, how would I know what kind of buffer kit I need to get?

[@d.j._angel8166]

Any buffer kit should work. Aero I recommend, for my AR is a Ballistic Advantage and I Got Aero's enhanced buffer kit and it fit great, so I would assume any *Decent brand Buffer Kit Should Work.

[@rogerdoger5]

Isn’t there supposed to be a spring under the backplate?

[@blakegarner5871]

The aero has a set screw to hold in the detent

[@protopiper5567]

I know this a old comment but that’s your take down pin detention spring. He installed it in the first lower video but for most other builds you’ll have to stop before threading down your castle nut and install that take pin and spring. I was wondering the same thing until I saw his message pop up in the video when he gets to that point. Hope that helps someone out there.

[@GreggRoberts]

How did you get the spring onto the buffer end without having a hernia? My spring is too small to do that. It's a standard carbine spring.

[@Chris-fj9ir]

Sir you forgot the safety switch selector spring.... is their something I missed?

[@danielsoto539]

Was the last thing on the previous video

[@walteryasiejkopmp6076]

I accidentally the buffer tube OVER the top of the buffer pin, and now I can't back it off the pin because it is nested in the bottom notch on the tube. How can I fix this, and back off the tube from the pin? Will I destroy the pin?

[@dundeeecroc]

3oz buffer?

[@mathewphillips4185]

Do you offer tool kit for ar 15 build,??

[@mick5740]

What about the rear take down pin , spring and detent?

[@1stShotTactical]

Those were installed in the previous video in this series! Check them out on my channel🙌

[@JimmyCzerwinski-p4g]

It's in aero precision has a bolt holds it in

[@matthetzel8026]

Take a shot every time u say detent lol

[@ezzieharrison3907]

What about the rear push pin spring,? did you happen to forget about

[@Alop777]

He installed it during the previous video. The Aero lower has a threaded pin that secures that spring. All lowers should have that convenient feature IMO.

[@zachj9045]

What about the rear detent spring

[@GA-cy8hm]

👏👏👏👏👏

[@tcdnuss68]

Um, what about the breakdown pin detent and spring

[@1stShotTactical]

Continue watching the playlist and I install everything!!🙌

[@Yarikk734]

Did you put the finish on the lower yourself? I went to Aero;s site and didnt see a finish like that

[@1stShotTactical]

Nope it was one of the limited released camps from Aero!

[@markparker7778]

Aero's channel is good but this is the real deal. THANKS!

[@JUDGERAMBO]

Any reason you choose the standard buffer assembly over the AERO enhanced buffer assembly?

[@1stShotTactical]

Lol not really, the standard buffer is what my local gun store had in stock so I went with it😅😅

[@MikeWizztactical483]

What was cost for complete lower

[@jamesdelong6401]

Is the lower on the VR80 the same way

[@tomwolves6953]

Aren't you supposed to use grease on the threads and spring?

[@1stShotTactical]

You can! Before you actually fire the gun fully assembled, def lub it up well!

[@bryanbernet4083]

Lol u came to his video to learn something than thought you should critique him 😂 only online 😅

[@tomwolves6953]

@@bryanbernet4083 That is how you learn is by "asking questions" do you think this is the only video that I have watched? get over it.

I've been using this tutorial for my 300blk (thank you!) Would you happen to know what buffer weight I should be using for a 300blk 16" with pistol length gas tube? I'm thinking about BCG MK2 buffer but no idea if it's gonna work

[@themightycrixus1131]

What kind of rifle are you building? 16" barrel, do a carbine assembly. 20" barrel, do a rifle assembly. Anything below 16" do a pistol assembly. Buffer weights are a whole different story

[@Chingus696]

Don’t understand the tighten, loosen, tighten again…. From an aerospace quality manager.. I don’t see that doing anything… just tighten it and stop…

[@Romefeller_]

Why does my retainer look old and ugly

[@1stShotTactical]

Hahaha that is a good observation and point😂😂

[@theresister5120]

Terrible advice. You have to torque the castle nut

[@MsPatriotfront]

You shouldn't post a video "teaching" people to do this when you don't know how to do it. You fail to apply anti-galling grease to the buffer tube. And If you go off camera to do the most important steps then what's the point of this? "Nice and tight" or "a little more torque" is a NO-GO. This is not a superfluous detail. Also, describing staking in the abstract is not helping anyone. Do the community ( and yourself) a favor and delete this pablum.
