Sami, this is a full power supersonic load Sir. It can be shot out of a short barrel AR. A linear muzzle brake will help channel muzzle blast away from the shooter - budsgunshop.com/product_info.php/products_id/714015131/midwest+blast+diverter+pistol+30+cal

super sonic ammo and will work in any 300 blackout

These are regular rounds I guess. You can shoot them out of anything chambered for it dude.

It’s regular ammo I believe. Direct impingement, gas piston, suppressed, unsuppressed, inertia, bolt, pump, supersonic, subsonic, rifle, mid-length, carbine or pistol – Hornady BLACK ammunition delivers superior performance for a variety of applications.
