Cor-Bon AAC .300 Blackout 150gr FMJ Ammunition, 20-Round Box

Cor-Bon AAC .300 Blackout 150gr FMJ ammunition (brand part no. PM300AAC150) loads a full metal jacket bullet for shooters running the increasingly popular .300 Blackout platform. Cor-Bon builds this round under its AAC-spec line, engineered to run reliably through the same magazines and bolt as a standard 5.56 AR-15 with nothing more than a barrel change. The 150-grain FMJ bullet resists expansion and holds together, making it a dependable choice for range training and high-volume shooting. Whether the host rifle wears a full-length barrel, a pistol-length upper, or an SBR, this load is built to cycle cleanly across the platform’s many configurations.
