Which BCM barrel

**tacoops** · 07-23-14, 06:54

I'm building a precision AR and don't know too much about barrels. I was looking at the 20" barrels on the BCM website and was hoping some one could answer a question, will I get more accuracy out of the standard barrel with a 1/7 twist or the SAM R barrel with the 1/8 twist?

Go with their SS barrels. I personally run the 16."

My theory is if I put the money in the barrel, trigger and scope and can get by with spending less on the other components.

What ammo will you shoot? What distances will you want to shoot? What are you accuracy expectations?

Ammo will be an experiment to see what performs the best. There is a range close to my house that goes out to a thousand yards, I'm hoping to be accurate to six hundred max. I've never done long distance so I don't want to spend beyond my skills if that makes sense.

But I would also like to have something decent to start with.

With a decent scope, ANY BCM barrel (but probably SS), and 77 gr SMKs, you'll be shooting 600 yards no problem.

My WOA 18" varmint upper with 1 in 7" twist on top of a Colt LE 6920 lower with a SSA-E trigger shoots less than 1/2" five shot groups at 100 yds. Give them a call they may have them in stock and ready to go. The 20" are only $285 with fitted gas manifold.
