I have a small amount of mostly subsonic factory loaded .300 blackout. I'm getting out of the cartridge entirely to pursue some other projects. Not willing to split, you either buy everything or nothing. Not particularly interested in trades at this time unless they're towards select NFA items, night vision related gear, a recent production Mini14 tactical or a Colt midlength carbine (CR6960).
