After some thought, I think I've decided to go with a 300 BLK primarily subsonic and suppressed. I'm probably going to go with about a 8 1/2 to 9 inch barrel and a 6 1/2 inch suppressor. Planning on using a pistol brace to avoid the need for an SBR stamp. And lastly, while I wait for the suppressor, I was thinking about getting one of the "mock" suppressors, just to simulate having a similar length and weight at the end of the barrel for purposes of muscle memory.

Progressives are the most open minded, tolerant, and inclusive people on the planet, as long as you agree with everything they say, and do exactly as you're told.
