The A1, as well as the 3 prong and various longer flash hiders for the carbines, were not intended to be indexed. Once you've hit that torque level, stop. The A2 and some other muzzle brakes were...

I don't use Loctite on any part of my ARs anymore. When I first got into building, I used to Loctite the gas key screws but now that I'm into "retros" I stake them. I know Colt puts Loctite on the...

The aluminum stocks really are more of a retro item now. My Colt (mil-spec) stock is a much tighter fit on the buffer tube than my commercial stocks. As far as weight goes, my '80s plastic stock body...

By chance did you look at your fired casings? I'm thinking a sticky chamber may be causing the extractor to tear the "rim" of the casing slightly therefore making bits of brass shavings. I've never...

I'm guessing torque would be the same with a crows foot as with a barrel wrench. If I'm thinking right, they are both offset and not directly in line with the tube. I use USGI tools and a crows foot...

I bought two Colt .223 marked at a gun show a few months ago for $20 each. Condition was VG-EX.

Essentially. Because flat-tops are made with a bit more metal on top for the rail. In order to try and keep the "carry handle" on a flattop, they had to reduce the space for your fingers to carry it....

Numrich is out of the complete buffers but have a few internal parts available. There is at least one on Gunbroker now. Opening bid is $100.

When Brownells sent me the email about those barrels I thought I'd try one because of the non-M4 extension but then I read that they had F marked front sight bases and decided against it. I can live...

I've been buying my barrels from AR15SPORT.COM. They have 1:12 Chrome Lined Lightweight barrels for about $250 and the front sight base is properly pinned so you're ready to go out of the box (you'll...

I've never had an issue with the selector not turning but have had it turn roughly. In that case, I either de-burred the selector detent channel or after making sure there wasn't anything foreign in...

Check out ar15sport.com for lightweight barrels. As Tony the Tiger says... "They're GREAT". I've been buying the 20" Lightweight Chrome Lined with 1:12 twist. They also have a 1:9 Non-Chrome and a...

I've seen many pictures of 3 prongs and they seem to be randomly set. Once the torque was reached, I would imagine the armorer stopped tightening regardless of position. I however, like to get the...

As a builder and collector of the "old" AR-15s since 1985, I found my "home" with RetroBlackRifle.com. All my builds are based on the 600 and 700 series rifles/carbines with one exception... an...

I would concur with paul v.

I got the chance to do a couple hours of shooting with my buddy this past Sunday with the express objective of finding out the trouble he's having. Long story short... Nothing he used (rifles, ammo...

tmark, here's some more info I got from Walt Kuleck and Scott Duff's book The AR-15 Complete Owner's Guide, copyright 2000... PWA (360) 438-3983. Serial numbers below 35222 are Pre-ban. Post-ban have...

I believe Pac West Arms went out of business sometime around the '94 "Assault Weapons Ban". I have a Pre-Ban A1 style and a Post-Ban A2 style lower, but I'm not sure of the mfg dates. I haven't seen...

Here's an update. The second mag didn't change anything in the SP1 but he did have a few 2-3 round bursts in the A1 retro (presumably slam fires from the before mentioned issue). Not sure why the AR...

Here's some history on this. As you may or may not be aware, the Colt conversion has a roll pin that is actuated by the charging handle to pull back the bolt and chamber a round. However, for some...

The brand is COLT (as in the title) ;)

Hello everyone,
My buddy called today to let me know his recently purchased conversion wouldn't lock the hammer back to fire another round. It would however, move back enough to pick-up and...

Your first two questions are essentially the same. Roscoe Snyder is correct, around '71 is when Colt started to transition to the "A1" stocks, with the fixed swivel and trapdoor. My 1974 Colt catalog...

I'm not sure what the AR18/180 had for a firing pin but what you seem to have are a large and small head for the AR-15/M16.

Can you include a pic?
