Thanks!
The piston system is the main thing, though a side charger would be good as opposed to the awkward AR15 style charger.
OK, that's one...has anyone ever tried one of these piston uppers by BRA? Any good? I see they have two piston systems, "CAPS" and "LPR" - both with regulated gas blocks, which is a plus.
Any other 6.5G piston gun manufacturers? I see that Alexander Arms used to make them, but stopped for some reason.
