    This is my 3rd G/Mntn barrel, what's that tell you?
    I am impressed with the staff when I need guidance and their quality is spot on. I wish they put all the specs on the barrel and their name, otherwise perfection is what you get at a fair price.

    I’ve spent hundreds on high end barrels and decided to try the 6.8 for a budge and was blow away. I’ve only bought green mountain since. This 300blk out shot 3/4 moa at 100 yards with factory 120 grain rem.

  5. great barrel, great company, fast shipping 5 Star Review

    Sub moa on 16" 300 all out. Had issue with adj. Gas block but swapped it out got a straight port and runs like a sewing machine. Well done guys, love your barrels.
