Griffin Armament is proud to introduce DUAL-LOK™, our 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). This page is for the DUAL-LOK™ FlashComp, a combination compensator and flash-hiding muzzle device. 

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. 

The DUAL-LOK™ FlashComp incorporates vast R&D resources from years of testing recoil-compensating and flash-hiding design geometry. The DUAL-LOK™ FlashComp behaves as both a compensator to mitigate recoil, and a flash-hider with its three-prong flash suppressing end geometry. Gas is directed out and away by the sloped channels CNC-machined behind the flash-hiding prongs. The ACME thread ensures rapid installation, while the taper ensures repeatable concentricity, and acts as the first locking mechanism. The second lock is achieved when you engage the DUAL-LOK™ retention ring with the splines machined into the muzzle device. This second lock ensures that your DUAL-LOK™ suppressor isn't going anywhere, and the 120 locking positions ensures the suppressor is locked into the same position every time for minimal & predictable POI-shift & accuracy. Unlike similar ratchet-locking mount systems on the market, the DUAL-LOK™ system is free of wear-prone, metal on metal parts that loose their effectiveness over time with use.

    Great build quality and will work great with Dual Lok can setup. Works very well on 308 and 300 so far. Will be using these for future setups. Great company and engineering
