Just want to make sure. Will this shoot a .300 Blackout? Manufacturer Answer

Yes, the .300 Blackout is a .30 caliber projectile so the .30 caliber muzzle device option will work, just be sure that the thread pattern matches your barrel. The standard thread pitch for .30 cal is 5/8x24tpi.

Product Info for Breek Arms BFO Flash Hider Cage Style Outside Threaded Muzzle Device

Breek Arms lineup of Outside Threaded Muzzle Devices is an affordable upgrade that gives you the option to run a flash hider or muzzle brake while utilizing our Breek Arms Castle Blast Shield as a forward blast diverter or concussion device. Simply slide the blast shield over the outside of the muzzle device and turn the blast shield on. This gives the shooter a more pleasant experience when firing especially for shorter platforms that tend to have an overbearing concussion.image
