The quad-tine flash hider endcap was painstakingly tuned in conjunction with the low backpressure baffle stack to kill flash at a level almost unseen in other low backpressure suppressors available on the market. This suppressor was optimized for 5.56mm platforms, with the capabilities for high performance on 6mm projectiles.
