    Haven’t test fired yet but over looks good.

    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.

    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!!

    Excellent fit and finish

    Looks perfect. Haven’t finished the build this is going with but upon first glance it looks flawless!

    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).
