  1. Anonymous (verified owner) –

    Haven’t test fired yet but over looks good.

  2. Troy B. (verified owner) –

    Fix and finish we’re excellent and roll pin for the gas block fit tightly. Have not had a chance to sight in for accuracy just yet.

  3. Justin C. (verified owner) –

    Great deal on a pinned gb barrel! It printed 1.25” groups with 77gr smk’s off a backpack with a nice pile of brass at 4 o’clock, running a sprinco blue spring and H1 buffer. This will eventually be a suppressor build (damn NFA) and it’s looking like it will make a great setup… Thanks for your great service BKF!!

    Really like this 12.5 inch barrel from BKF. Sighted in red dot at 36 yds. Was getting 1/2 inch groups at 36 yds with Federal xm193 55 grain ammo with no magnification (red dot only).
