These 200 gr. .300 AAC Blackout subsonic cartridges feature the REX projectile made by Maker Bullets. Their attention to science and precision is unmatched and it definitely shows in the ballistics. They perform best in AR platforms with barrels that are 12" or less.
The projectiles are CNC machined lead free copper and engineered to perform flawlessly upon impact with flesh. Their design results in extreme trauma from devastating temporary and permanent cavitation making them top choice for hunting and defense by professionals all over.
To be sure of proper bullet stabilzation and prevent accidental suppressor damage we recommend to first discharge a few rounds at a clean target without a suppressor attached. Then observe target for signs of keyholing. If none is present then discharge with suppressor attached. If this subsonic ammunition will be discharged in a gas operated firearm it is recommended that such firearm incorporates the shortest length gas system possible or at the least an oversized gas port with an adjustable gas block installed to ensure proper functioning.
