    I have yet to put any rounds through it, but I was very impressed after inspecting it. Machined well, beautiful finish and just very happy with the overall purchase. Not going to find it cheaper anywhere else.

  2. Dylan Allen (verified owner)

    Fine barrel with excellent quality. Super solid finish, excellent rigidity and harmonics, superb accuracy for barrel length. With me behind the trigger shooting offhand I couldn’t miss and shooting minute to 1.5 minute groups when concentrating and breathing. Only thing I recommend is to get a dimple jigs as this one is not factory dimpled for a gas block.

    Like above I dimple all my barrels so no issue there.

    My review doesn’t really have anything bad to say about BKing…it has more to do with ballistic advantage needing to stamp their barrels if it’s been MP/HPI

    Great price. Fast shipping!

  13. Alex (verified owner)

    Great price and quality, shipped quickly. The only downside is it is not cut for a front sight post, but thats on me. Would be fine for a free float rail.

  14. Elliott (verified owner)

    As always, B Kings has the best price around, and shipping was very fast. BA barrels are always a win for me.

    Perfect for SBR
