Reviewer: C.Smith from Ga  
This is an amazing company great shipping time. Updated throughout the whole process. 300 blk upper was suppose to be m lok. There might have been an disclaimer saying it was going to be key mod but I don’t remember. Finish was excellent. Barrel shot tight groups. I’m very pleased with everything and item wasn’t overpriced. Great Job you Guys/Gals at your company!!
