ive got one and its a fantastic kit. just be sure you clean the AR15 before shooting .223/5.56 after using the kit. 22lr is DIRTY. get the chrome cmmg kit it easier to clean. i got mine before they were available.
if i got 22lr ammo that doesnt work in my other 22s it goes into the cmmg pile. that thing eats everything.
cmmg kits do not work with piston systems.
