I tried searching but didn't find an answer. Can you mix and match A2 fixed stock lowers with carbine length uppers (carbine gas length system) as well as M4 style stocked lowers with rifle length (rifle gas length system) uppers? Mid length as well? And what about the 18" SPR's or 16" barrels with rifle length gas systems? I'm just curious.
TIA! o.r. |
