Simple question, but as title reads: did the Armalite prototypes, say #'s 000001, '02, '03 all have the old 'Edgewater'-style buffer? SoAR's video on his gift Proto AR-15 clone didn't cover that, and frankly I'm unable to find evidence anywhere else that beyond early Colt 601s were 'Edgewater'-style buffers used.
Granted, it makes no chronological sense to believe that regular rifle buffers were used in the prototype Armalites, but then which buffers did those use? Can someone provide photographic evidence perhaps? Haven't been able to find photos of these parts from KAC's museum online.
