    Great price fast shipping

  2. Joshua S. (verified owner)

    Looks perfect. Have not had a chance to put it together and put any rounds through it yet but it looks flawless

  3. Joshua M. (verified owner)

    Good product. I’ve only put about 300 rounds through it but, was hitting an 8 in steel plat at 400 yards. Had no issues with consistency

  4. Darren S. (verified owner)

    This is looking to be my go-to barrel for budget to upper mid-range builds going forward. Quality and accuracy is excellent. Getting a barrel of this quality, with a pinned gas block, at this price, is tough to beat.

    This is a great barrel for a great price point the only complaint is the pined gas block was drilled a little crooked but pin went in and so far has stayed in on a 100rd and I’m getting about 1moa with cheap ammo I bet match ammo I can get 1/2 Moa or something this is my second barrel I got from BKF.
