Normally when you buy a dedicated .22 AR barrel it comes with the adapter that goes right on the CMMG/Ceiner bolt assembly. And like he said you pop the .223 adapter off and pop the dedicated .22 one on. All you have to do. Everything else is AR. Now if you don't already have an AR CMMG conversion kit you will need to buy some or almost all of it to get the parts you need which are everything in the bolt and carrier.
I went from a conversion kit to a full on .22 AR so I know the drill.
