GRIFFIN PSR DUAL-LOK PALADIN BRAKE 5.56

The PSR (Precision Suppressor Rifle) DUAL-LOK® 2 Port Muzzle Brake 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® 2 Port Muzzle Brake is equipped with two rearward directing recoil reducing ports with vertical compensation slots the two port brake provides flat shooting performance in addition to maximum braking power. 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 2 Port Muzzle Brake is machined from high strength 17-4 stainless steel that is corrosion and wear resistant. - 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. - Diameter: 1.075 [splines] .93 [unit] - OAL: 3.6 1.05 added length - Weight: 3.0 ounces - Materials: 17-4PH Stainless Steel - Finish: QPQ - KEY POINTS : - Utility patent pending - Wear free mounting system requires no consumable parts - 2 Sacrificial baffles to extend the life of your suppressor - Taper lock interface ensures security and accuracy - 120 effective positions ensure a rock-solid suppressor mount and provide extremely low POI shift - 17-4 PH Stainless steel - Nitrided black for increased surface hardness corrosion and wear resistance - ¾ wrench flats on muzzle devices - Shims required included
