Awesome little package - CMMG 22LR Mk4 Barrel Kits w/ Bolt Group

put it together in a Aero Upper and Matrix arms handguards. ive only shot it with a suppressor on and its ran great. However with Subsonic rounds it doesnt work. Used Cmmg magazines and going to try Black dog magazines shortly. Also even tho its only a 4.5 inch barrel its extremely accurate. and still has enough power to kill small rodents, killed 3 possums already. Totally worth the buy.
