**Colts AR factory triggers suck and they're incredibly overpriced for what you get**

The Olympic Arms (SGW) rifle I had, had a too tight chamber and keyholed 1 out of 4 bullets.

Tha Armalite rifle also has a tight chamber.(I asked.)

I got a Colt and replaced the factory trigger,with a Jewell triger. I can cover 5 shots with a quarter at 100 yards.

Have you tried the dry teflon sprays?

Colt rifles for civilian sales are chambered for .223 Remington, not 5.56mm NATO spec ammunition. The rounds are similar, but not identical. I can't speak for Bushmaster or Armalite but I suspect that folks calling them 'tight' means they are firing incorrect ammunition.

'Keyholing' is usually caused by using the incorrect bullet weight for the twist of the rifle. The slower the twist generally the lighter the recommended bullet. Older Colts stabilize the 55 grain bullet better than something like the new 62 or 70 grain bullets.

I'd look to that first instead of worrying that my rifles throat was 'tight'.

Also, those Jewell triggers are mighty nice. They're also about a hundred bucks or so, plus the cost of installation. The least expensive Colt I saw was around $1200 or so. If I'm plunking down that kind of cash, I expect that it have a decent trigger.

My RRA set me back about 2/3rds of that, freeing up some cash for a nice Aimpoint optical sight, extra mags,mag pouches, a decent sling, and money for primers, bullets, powder, and dies.

I handled the Colt product daily for more than just a little while when I was in the Corps. When I had the opportunity to add an AR to my gunsafe as a civilian, I chose the RR.

As I said before, this is just my two cents. Your mileage may vary.

"Colt rifles for civilian sales are chambered for .223 Remington, not 5.56mm NATO spec ammunition. "

My SGW (Olympic) was chambered for 5.56 and would not fire my reloads. It required small base dies to reload. My Colt fires both reloads and new bought.
My SGW keyholed it's shots even though it was 1/12 twist and the bullets were all 55 grains.

The Jewell trigger is a drop in type which gives me 1" at 100 yards.
Several people I work with have different rifles, yet they also shoot well.

Strange, 25 years ago gun mags were saying the AR-15 was inacurate for target use.

Have you tried the dry teflon sprays?

Yeah, sure. But they aren't really all that dry, and still become dirty.

If I were to purchase an M-16 look a like I sure wouldn't go with the AR-15. I don't like the AR-15 gas system which introduces propellant gases and the associated carbon fouling back into the weapons interior.

I would purchase the AR-180B. The AR-180B doesn't spit carbon fouling back into the weapons interior.

Does anyone know if the Barrett M-468 also has the problems of the AR-15 concerning the carbon fouling?

The website below offers AR-15 uppers that greatly improve the AR-15 rifle. The P-416 gas system does not introduce propellant gases and the associated carbon fouling back into the weapons interior (a fault in the M-16 rifle).
