  1. 38 Caliber, 1:18 Twist Barrel 5 Star Review

    Posted by on 1st Apr 2021

    Great project barrel. I build airguns and firearms as a hobbyist. Was on the lookout shopping around for a 38/357/9mm barrel for an airgun build. Once again Green Mountain pulled through with the goods at a reasonable price.

    Craftsmanship is always top notch with GM. Prices are more than fair, too!

    This barrel fit the specs I was looking for.

  2. Perfect barrel blank for my 20ga shotgun adapter for 38 Special! 5 Star Review

    Posted by on 29th Aug 2018

    I could not believe the dimensions of the barrel blank -- they were just what I was looking for to build an adapter to slide into my 20ga barrel. The large collar at the end was perfect for turning down to copy the rim on a 20ga shotgun hull. A portion of the barrel had to be turned down a small amount to slide into the 20ga bore. All I need to do now is wait for the rental reamer to arrive to cut the chamber -- the crowning has been done.

    Once again GMB delivered a great barrel at a price I could afford.
