yes Rudy aka Mad machinist mad me a 762x25 upper and thats where i got the idea from
the pic was from akman from another site
Ha! Love finding my work on other sites. That little snubby AR above has a 3.625" barrel on it. Had to move gas port forward in block and modify carrier and spring to run a shorty buffer tube.
damn it 4th has got to see that!
my 7.5" is already finicky with ammo. Can't imagine going any shorter. Anyone have a link to the cdnn piston kits or are they a thing of the (recent) past?
