Been watching the guys with the Mini 14 and some of their groups. What kind of AR are you shooting and what groups are you getting at 100 and 200 yards.
Mine is:
Olympic PCR-16 1 x 9 twist bull barrel flat top. I have added a bushmaster 2 stage trigger, Pneumatic Recoil Buffer, KT15 Weaver scope with AO and a harris bipod BR. I shoot FMJ 55gr. Black Hills ammo.
My best group at 100 yards with 5 shots was 3/4+".
My best group at 200 yards with 5 shots was 1 1/2" .
My best group at 300 yards..........dang range is only 200 yards.
My goal is to shoot 1/4" group that they advised the Bushmaster 24" barreled varmint rifle. (No flame intented bushmaster owners)
