GREAT value!

Posted by Heriberto Rivera on Mar 20th 2025

My once shabby machine was having all manner of problems jamming and not feeding right. All but bcg had been replaced. Got this beauty and slipped it in the after a good lube job... BLAM... At the range that is. Just finished running a few hundred rounds thru it and it's never run better. Highly recommend this. Especially for the value!

Quality BCG and fast shipping

Posted by Thadius M. on Jan 11th 2019

Only downfall was the pin to take it apart had to be filed down to fit back in because it was bent. Not a big deal. Can’t beat the lifetime warranty though! Easy company to deal with great shipping. Had no problems.
