Griffin Armament is proud to introduce DUAL-LOK the newest QD mounting system for rifle suppressors. The DUAL-LOK system is comprised from two parts the DUAL-LOK Mount and the DUAL-LOK muzzle device (of your choice). The muzzle device integrates 60 machined mounting position grooves which is doubled by the mount’s two locking positions hence the double entendre DUAL-LOK. 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. Time intensive R&D resulted in a high performance 3 prong flash hider with incredible resonance reduction. These suppress flash extremely well and do not ring or ping when fired hence “stealth”. CNC Machined of heat treated 17-4 ph stainless steel material and Melonite QPQ treated ensures durable corrosion free service life.
