  1. Pleased with what was received... 4 Star Review

    Posted by on 27th Nov 2017

    Best barrel packaging I've received to date. The visual inspection has proven to be a joyful success, and the letter I received a few days later was appreciated. Most company's send off a sticker and at best a note to remind you to buy from them again. Green Mountain just sent a follow up thank you. I'm building the rifle for this barrel now and will be a few months before I'm able to test fire. I've heard quite literally nothing but good about Green Mtn barrels, and so far, my experience has been on point with those praises.

  2. Very nice barrel 4 Star Review

    Posted by on 27th Nov 2017

    Had a FSB professionally installed and then assembled into an A2 configuration. Zero problems with the barrel. Very accurate considering the iron sights and cheap ammo. Even with some old Norinco ammo. Just keep a spare extractor or two for the bolt. Would buy another 7.62x39 barrel from GM again.

  3. Awesome performance 5 Star Review

    Posted by on 7th Aug 2017

    Re-barreled an upper that was chambered in 7.62x39 I was very impressed with the accuracy ran 500 round no problems held 1 inch groups at 100 yards. I'm impressed.

  4. Best money I've spent in a while even though I missed the sale! 5 Star Review

    Posted by on 5th Jul 2017

    Built the upper with the GM barrel and a BCG that was recommended and 10 round ASC mags. The AR shot unbelievable considering I was using Wolf, PPU and old TCW ammo. I was too much fun to describe having the AR shoot so well right at the start. I love the chrome lining so I don't have to clean as often. Really nice barrel!

  5. A solid barrel for anyone's home build 5 Star Review

The barrel cleans up easily, what more can a man ask for in a barrel?
