  1. I like it so far 5 Star Review

    Posted by on 29th Jan 2016

    But for my build I did not get further than polishing it up. I got the SS .905 barrel and decided to leave it at that, only smooth it up.

    After hour on the lathe, it looks beatiful.

    Will post an update eventually.

  2. very accurate 5 Star Review

    Have tested with 69,75,and 77 grain bullets.Awesome barrel. Best with bullets seated a little taller,which is limited by space in your magazine,unless you load into rifle one at a time. A little experimentation will put you into .4 to .75 moa! Drilled the gas port .125 and used a adjustable gas block. Turned down to .875 from gas pad forward. Thing is like a laser out to 300 yards. Best value I have seen anywhere.

  3. you bought a gunsmith barrel and now you need to put it in a lath and finish what they started! 3 Star Review

    I buy barrels from you guys so I don't hafto finish shaping the barrel the barrel was lathed 3/4 to the end and what looks like it is still in the rough hammered or something. But don't worry about it I don't have time to send it back I will take care of it I have an impatient customer. Tim

  4. As good as it expected! 5 Star Review

    Looks better than the photo in the description. Very good external finish, smooth chamber and bright bore. Bolt will not close on "Go" gauge, so chamber is a few thousandths short, but a light twist with a finish reamer will set it right. Overall very pleased with the product.
