Used by US armed forces worldwide, the US Dept of Homeland Security and law enforcement agencies across the nation, the Vortex flash hider features a patented 15 degree, right hand helical flute design that effectively eliminates muzzle flash. Machined from ordnance grade 8620 steel and finished with a mil-spec phosphate, the Vortex is a self-tightening flash suppressor that will not loosen or shift position under sustained fire. This Vortex flash hider comes equipped with M22x1.0 outside threads for use specifically with an OPS Inc sound suppressor. This model is designed for use with AR-10 rifles in 308 Win/ 7.62mm. Due to the design of the Vortex flash hider, no crush washer is needed to install this sight and it is not recommended that one is used.
Compatible with Silencer Mount OPS Inc M22x1.0, including 12th Model PSS / AR-10 / SR-25 MBS silences.
Manufacturer suggests using a M22x1.0 Thread Protector (Product # 672293) when an Ops Inc sound suppressor is not installed on the flash hider
