  1. Beautiful barrel but ? 4 Star Review

    Posted by on 31st Mar 2020

    For my uses I would give it a 5 star rating if it had a 1-8 twist it would be nice if Green Moutain would consider this. The workmanship is very good and it seems to shoot best with heavier 75 & 77 gr bullets.

  4. two more please.... 5 Star Review

    Posted by on 28th May 2018

    Bought this barrel for a shop build hot rod. Love GMB but never know about unique parts. Wow, shoots like a laser. Bore sighted at 90 and went to the range. 10 for 10 at 100 on a 10" gong with an RMR during break in. I'm no old world master shooter, bad dominant eye ... . Shipped next day, packaged appropriately, plastic cap on threads. Buy these guys with the utmost confidence.


  5. 16" ribbed 5.56 5 Star Review

    Posted by on 19th Aug 2017

    nice barrel, I have a 20" fluted stainless green mountain too. It dimpled with a jig and a 35 deg. cobalt bit like butter! But this ribbed is a super hard temper and I could not even hardly score it. I gave up and just installed the gas block without dimples. Love the barrel!
