digests anything it's fed except JHP rounds
It's a .223 receiver with a RRA adapter. I like the ability to use the Colt or modified Uzi mags over the Sten Mag based Olympic upper.Is that a dedicated 9mm lower, or did you use a 9mm adapter block in a standard lower. I plan on sending in the forms to do an AR SBR next week.
If its a 9mm block, which brand?
Does it feed factory 9mm JHP -- things like Winchester SXT or Gold Dots?
I'm partial to the standard A2 grip. Haven't found any others that I am comfortable with.Pretty nice rifles. Only thing I would change is the grip. I just can't stand the standard AR grip. Magpul makes a nice one without the finger bump.
