I wanted to do a 300 BLK on a short barrel with a silencer on a build I was doing but realized I couldn't get the can without a stamp and I'm not fucking with that shit. Combine that with the inability to find ammo or the proper parts and I decided to punt on that idea for the time being. Also I don't remember if short barrel will give optimal burn but it probably doesn't matter for this type of build.

Mrgunsandgear did a good video about 300blackout barrel length velocity changes.
I think 9-10 is best length including suppressor for maximum shush/slappage
