AR-15 BS Thread

I've built 3. Take your time. Buy quality parts. If you have a friend that's done it before and doesn't mind helping you that's a great resources. If not, There are more than plenty of youtube videos to help you out. Here's the three I built.

 

Wouldn't a field strip just be separating the lower and upper and taking out the bcg? Where if you build one from a stripped lower you have to add in all of the small parts to construct the lower. I am sure it isn't too hard with all the stuff on youtube. I have only bought a complete one but always field strip and clean it after each use.

One day I'll put a lower together like this

 

Nice. I've always wanted to do it, and I have a couple different AR handbooks. Just never pulled the trigger, so to speak
I'll order up a parts kit this weekend. Thanks!

 

As docloco said if you take your time and are patient it's pretty simple, I've built 2 lowers for myself and 3 for friends. Never an upper though, haven't been able to justify cost difference. The small parts can be a pain but you get better every time, especially once you add more and/or better tools to do it.

 

and if your friend does mind helping you, then he's not a friend lol

 

Haha everyone I've met out here just bought theirs complete. I've got plenty of precision tools and technical know how

 

Building the lower is very easy. I've done 2 and planned on building the uppers both times as well but a complete upper can be had so cheap I really don't see the point. I didn't have any friends with experience, just hit up YouTube and go to town

 

one of my mini-ARs that I built:

 

Ive built like 4 or 5 uppers (sad i cant even remember now) and have built 3 lowers now. The first time on each was just by myself and youtube/guides found online. Its pretty dang simple. The uppers are a little bit harder but not that bad really

 

A barrel nut wrench and a vise are really the only specialized tools you need. It's easier with a $30 upper action block, but it's not absolutely required. Other than that, punches, an adjustable crescent wrench for the muzzle device and a hammer are all you really need. I don't do it professionally but I've built a double handful of them.

 

Sweet. Gonna start stockpiling parts soon. Thanks guys

 

I assembled my lower (From a stripped lower, LPK, and stock kit) and bought an assembled upper, but I have since rebuilt the upper in a different caliber.
You don't really need a vise if you have some ingenuity, but I recommend getting one.
This is what I used.

 

headspacing with an AR isnt really an issue if you buy a barrel and bolt from a reputable shop. It's not like an AK where you have to actually set the headspacing. I've built 3 uppers from random distributors the internet with barrels from one company, bolt from another, etc, and never had a problem. The biggest headache with building uppers is hammering in the pins for the forward assist and gas block.

 

I don't do it to justify cost difference, I do it to have what I want the first time so I don't have to change it. However, I have changed rails twice. But my barrel, receiver, bcg, and brake have not changed.

 

Came across a good deal on a stripped lower and had to pick it up. Currently have a 7.62x39 7.5in, .223 16in, and ar-10 18in. Ideas for this new one? Thinking a 223 wylde chamber and I want to try a cmc flat trigger

 

223 wylde is the shit.

 

300 Blackout?

 

.458 Socom, there is also a new .375 Socom caliber out there.

 

Are you thinking of .375 specter?

 

Nope, Tromix now has a .375 Socom caliber for sale. Barrels, bolts, gas blocks, etc.
