"From the moment you open the box you will see why CMMG is one of the best lowers you can buy. This lower is as pretty as it is functional. Having a dedicated lower means no messing around with a mag block and everything fits together tight and precise. I love this lower and if you like quality you will too."

"Worked like a champ with a JSE Surplus upper. No jams or FTF. Fun to shoot and right on at 50 yards. My 10 year old loved it too."
