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. The new G6A3 Vortex comes equipped with a grooved exterior for less contact surface and reduced carbon build up, making the removal sound suppressors easier. Compatible with Gemtech HALO and Smith Enterprise/Fisher quick attach/detach Direct Connect (DC) silencers.
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.
