Griffin Armament PSR DUAL-LOK Flash Hider - 30 cal.

The PSR™ (Precision Suppressor, Rifle) DUAL-LOK™ Flash Hider is a precision DUAL-LOK™ muzzle device made specifically for the DUAL-LOK™ PSR™ suppressors. PSR™ (Precision Suppressor, Rifle) over the barrel suppressors provide unprecedented blow back reduction, sound performance, and accuracy.

The PSR™ DUAL-LOK™ Flash Hider is equipped with 3 flash suppressing tines. Also incorporated into the muzzle device, a taper surface to ensure solid lock up and minimal/repeatable POI Shift. The muzzle device integrates 60 machined mounting position locking grooves, which is doubled by the mount’s two locking positions, hence the double entendre DUAL-LOK™. How is this achieved? The mounts’ two locking positions are machined out of phase of one another by 3 degrees which provides the 120 effective locking positions and ensures a tightly mounted and locked suppressor.  When the suppressor is installed, only one of the two positions will generally function by allowing the spring to push the locking collar rearward over the splines.  Melonite QPQ provides a durable, attractive finish. The PSR™ Flash Hider is machined from high strength 17-4 stainless steel that is corrosion and wear resistant.

The flash suppressor does not require timing.

Host Firearm Barrel Requirements : 1.95" rear of the thread shoulder needs to be .775" OD or smaller in order to provide clearance for interfacing.  The tool used to cut this step if applicable should have a .016" corner radius or smaller, or the corner radius should be compensated for by adding length to the 1.95" step.
