Built entirely from 17-4 H900 stainless steel and finished in durable FDE high-temp Cerakote, it uses a low back pressure baffle stack and quad-tine flash-killer end cap to provide smooth shooting characteristics with impressive flash control on .308 Win, .300 WM, and similar cartridges.This Optimus 7 Tap Mount model is ideal for shooters who want a robust, full-auto-rated suppressor for range use, training, or hunting with 30-caliber rifles. Its 1.73-inch tube diameter increases internal volume for effective gas management, while the included EZ-Brake with 5/8x24 threads offers secure mounting on compatible hosts.
