What kind of accuracy are you guys getting out of your AR-15 1:7 barrels with 62 gr. M855 ammo at 100 yards?

    had a 1:8 twist. With the 855s/ss109s i could cover 3 shots with a dime no problem. Of course it was set up to be a bench gun anyhow.
    1:7 should do bout the same. May like a bit heavier bullet too. M193s will probley be slung all over the place

    It will be just as accurate as from and 1/8 or 1/9 twist. The 1/7 was adopted because the M856 tracer is so long it will not properly stabilize at a slower twist.
