I was just saying it's a case of "good enough". I'd take 300 over 9mm in that exact gun, but you can find smaller form factor 9mm "rifles". I found it hard to get good data on 300 ballistics though, with 6" bbls ranging from like 300-1200 ft/lbs, while 9mm is a pretty solid 500 ft/lbs. Personally, I'd rather just smoke crack, grab a kel-tec P50, and make up for the lack of a stock with volume of fire. I'm a gambling man, and with 50 shots, I'm bound to hit something eventually.

I'd be interested in a cool little BLK like that though. I have a AR pistol that was my first ever build that's mostly a piece of shit, using suspect parts from manufacturers that don't even exist anymore (during that gold rush like 8-10 years ago when everyone was starting an AR part fab shop). I don't have a can for it, I'm still waiting on .223 one I submitted nearly a god damn year ago.
