.300 Blackout Ammo

.300 AAC Blackout (.300 BLK) puts a .30-caliber bullet in an AR-15 using the standard bolt and magazines; only the barrel changes. Supersonic loads perform close to 7.62x39, and the cartridge was designed to run well from short barrels and suppressors.

We carry two full metal jacket practice loads. Magtech Tactical 300BLKB is a 123-grain FMJ with brass cases that Magtech rates at 2,230 fps from a 16-inch barrel; it's sold by the 50-round box, in 200 and 500-round packs, and by the 1,000-round case. American Quality N300147VP250 is a 147-grain FMJ sold as a 250-round case.

Both are range ammunition for zeroing, drills and plinking. If you shoot suppressed and want a subsonic load, use Request a SKU on the product page and tell us which one.
