Does anyone know if they make multi caliber .308 rifles? For example a rifle that is chaimberd in 308 but can also be used as a .338 or 300 black out.

All I ever heard of bro is that you can change out the upper on an AR15 for AAC300. The lower is the same but that's it for what I know. If you have an AR15 for 300.00 you can get the upper and mags for 300 blackout so there is some savings and as long as it's not an SBR no paperwork or tax stamp is needed.:cool:
