Is there a technical reason why no one seems to be interested in producing a 6.5 PRC gas gun or large frame AR? Is PRC that much larger than 6.5CM / .308?
AR15 sized rifles are modified to fit .308 sized cartridges by POF and now Ruger. Maybe similar modifications can be made to AR10 sized receivers with a mag to fit short magnums. That would be a neat concept.
