  2. great work 5 Star Review

    I ordered this barrel for a 1928 re-weld semiauto build. Threads are sharp and crisp. Fits perfect to the 1940-43 receiver and cutts compensator. The 14.125 length is perfect for the non SBR build. As short as possible without violating the 16" requirement. Fins are square and sharp. The machining of this barrel is outstanding and I would recommend this barrel to anyone building a non SBR Thompson sub machine gun. Thank you green mountain rifle barrel company. Top notch.

    This barrel is made to WAAAY better quality and historical accuracy than the one that came on my Kahr 1927A1. Fit my original Cutts perfect and accuracy at the range was prefect!!! Great product for those that don't want to mess with the Feds but have a closer to original look!!!
    Great company to deal with as well.


  5. Great barrel to make a non-sbr thompson 5 Star Review

    My cutts compensator fits perfectly, the fins do not match perfectly the original barrel but are significantly closer than other barrels. Oh yeah, its the only finned barrel that lets you make a non-sbr thompson!
    The chamber is a match to the original and has good rifling.
