  1. Best Value, Highly Accurate barrels. 5 Star Review

    Posted by on 4th Dec 2020

    This is my second GM barrel. Very pleased with the performance. Gassed right, accurate, and affordable. With 75gr hornady HPBT and RL15, i get 2734 fps avg, zero pressure signs. Magnetospeed reads an SD of 3 and an ES of 5 over 4 shots in a quick lot test i did today with a fresh batch of ammo that i loaded. My GM-M25 will do an SD of 8 and ES of around 25 to 30fps over a 25 round string. Excellent, excellent barrels. 13/10 would recommend.

  5. Exceded expectations 5 Star Review

    Posted by on 29th Jan 2018

    Since I’ve purchased and installed this barrel, I couldn’t be happier with the quality of workmanship that has gone into it. The bead blasted finish is perfect! And the fit to my Aero upper receiver is rock solid. So far in the last 10 days I’ve shot 180 rounds thru it, one outing at 25yards I was putting ball ammo thru the same holes and if not in the same hole close enough that a quarter would cover a 5 shot group of holes. Second outing was at 100 yards and did some ammo testing with 6 brands of ammo in different bullet weights and all preformed well but two brands I was able to get 1-1/4” groups with 5 shots. I feel very confident going hog hunting with this barrel!
