  1. Top of the line barrel 5 Star Review

    Posted by on 11th Mar 2021

    The heavy chrome lined barrel with the 7.62x39 cal is GTG the overall fit and finish is great.

  2. Outstanding in every way 5 Star Review

    Posted by on 27th Feb 2021

    Barrel shipped quickly. One of the few options I have found for chrome lined in this caliber. No range report yet as still gathering parts to complete the build, but visually perfect in every way inside and out.

  3. Fast Shipping, Greate Barrel, Outstanding Product 5 Star Review

    Posted by on 15th Feb 2021

    Received the barrel within a 5 days of my order. Solid packaging and you can tell it was shipped with care was a big plus for me. Added it to a BRS47 upper with no issues at all -- passed the headspace test and took it it to the range. Great accuracy at 100yrds and worked flawlessly for plinking. 5/5 would buy this again or any product from GM.

  4. Amazing accuracy 5 Star Review

    Posted by on 4th Feb 2021

    This barrel is exceptionally accurate. The fit and finish is phenomenal. Chamber is smooth and chrome lining is spot on. The rifle has no problems jumping between 50-300 yard steel and hits every time. On paper its will consistently shoot moa which is stellar for a slim profile ar barrel. I bought a couple of barrels before arriving at this one and hind sight 20 20 I should have bought this from the beginning as I would have been money ahead. Thank you green mountain for making a quality barrel state side

  5. You get what you pay for 5 Star Review

    Posted by on 26th Jan 2021

    Now let me start by saying I have not yet finished my build with this barrel so I cannot tell you about my accuracy results. But I can tell you that upon close examination it appears correct in every respect. The crown and hard chrome are as advertised. The machining and finish are error free. The rifling looks to be correct from the origination to the muzzle. No jagged marks in the barrel from the button that you find when worn tooling is used. My overall impression is that it is exactly as advertised. Now on a personal note I prefer hammer forged and broach cut barrels in that order over button rifled barrels. But this is a top notch button rifled barrel.
