Will RobArm offer 5.56 barrels with 1:8 or 1:7 twist rates?

Wierd because in the AR I see a benefit, it's not big at 100 but is noticable at 300 and beyond. Also Sierra recommend the 1:8 or 1:7 for the 77 grain tips.

Oh well, thanks anyway.

Only if you don't shoot it.

Out around 100 yards I don;t find that much difference unless you're spinning a light bullet too fast and make it fragment. Out at 200-400 yards, twist makes more of a difference as the bullet has stopped cavitating and will be stable. Then, twist and length matter more.
