We have 2 of these Ar platform rifles chambered in 5.7x28 with the CMMG barrel, BCG and magazine.
What makes these special is that we found a couple of new old stock AR Five Seven lowers to mount these uppers on so the caliber markings are correct.
Come check these out. One 50 round box of ammo included to get you started.
layaway available at no additional cost.
Thanks for your support.
