  1. custom martini 5 Star Review

    Posted by on 7th Nov 2016

    Very quick response, as this is about the 14th barrel I have gotten from Green Mountain for custom guns. I haven't had a bad one yet. This one is for a 357 mag on a Martini Cadet its not done yet but close. Looking good so far.

  2. good service as usual 4 Star Review

    This barrel is now part of a small receiver Rolling Block. --haven't yet accuracy tested as the sights aren't installed but it shows promise ------ could make holes in a coke can at 50 yrds just sighting over the recvr and barrel shotgun style.

  4. Fast service 3 Star Review

    Posted by on 14th May 2015

    Barrel was out the door the same day I ordered it . I hope to have it fitted soon and how it compares to the other barrel maker I have used in the past .

    Barrel was supposed to have numbers at the breech and letters at the muzzle . Everything was on the one end of the barrel so I'll have to figure that out
