I have a dedicated .22lr barrel,standard a3 ar15 reciever,and i need the bolt or whatever goes into the upper for it to function.Ive looked at the CMMG bolts,collars,and conversions but am not sure what all it takes to make it work in my rec.Any help would be appreciated
thanks

Barrel, bolt and collar. Everything else is standard––barrel nut, ect.
