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™ HUB Mount and the DUAL-LOK™ muzzle device (of your choice). This page is for the DUAL-LOK™ Minimalist Stealth Flash Suppressor

The muzzle device integrates 60 machined mounting position splines, 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 locking positions and ensures a tightly mounted and locked suppressor.  When the suppressor is installed, only one of the two positions will function by allowing the spring to push the locking collar rearward over the splines. 

Constructed of 17-4 PH stainless steel, the DUAL-LOK™ Minimalist Stealth Flash Suppressor has 3 flash suppressing tines which have anti-reasonance features integrated. The Minimalist Stealth Flash Suppressor weighs 2.4 ounces , substantially lighter than that of most competing flash suppressor mounts. The lighter weight reduces suppressor system weight while making the host firearm barrel lighter and more responsive to the shooter. The flash suppressor does not require timing.

    Suppressor QD brake, on CZ scorpion

    Published by Jayden Miranda on 9th Apr 2024

    This product works amazing, takes down recoil by quite a bit. And helped in making my suppressor QD system work flawlessly. Easy install and hasn’t come lose when torqued down, does not even require shims.

    Great quality

    Published by Kevin J on 8th Jun 2023

    First and foremost I have not yet made it to the range with this flash hider but will update when I do, looks very good, machining and finish quality are impeccable. Price is fair and I like that the wrench slot is not at the very rear, makes it a cleaner mating device at the end of the barrel. I bought this to go with their blast shield.
