CMMG m4 drop in 22lr kit

[rocketman]

I had the spikes conversion kit. I modified it a little and it ran aguila sniper subsonic perfectly. it was pretty accurate too because the faster twist rate worked much better in the AR barrel than any .22 LR barrel. It was super quiet through my buddies can too. It was the only semi auto setup i found that would run the aguila sss 100% and not keyhole.

are any of those kits FA rated?

Yes, most if not all of them will work full auto. I think some require an adaptor to do it though.
