Magtech Subsonic 300 BLK 200gr FMJ 50rd Box

Magtech's subsonic 300 Blackout load pushes a heavy 200gr full metal jacket bullet at about 1017 fps, below the speed of sound. With no supersonic crack, a suppressed 300 BLK rifle gets noticeably quieter. It comes 50rd to the box.

The FMJ bullet is heavy for caliber and will not expand, so treat it as a range and training round. Expect a different point of impact than lighter supersonic loads and confirm your zero. Some AR-15 builds need a suppressor or a gas system set up for subsonic ammunition to cycle it reliably.
