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 specifically for use with an OPS Inc sound suppressor. 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 OPS Inc Silencer mount M22x1.0, including M4-S MBS, M4-M MBS, 12th Model SPR MBS, 14th Model CQB MBS, 15th Model CQB MBS and 16th Model CQB MBS silencers.
Manufacturer suggests using a M22x1.0 Thread Protector (Product # 672293) when an Ops Inc sound suppressor is not installed on the flash hider.
