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™ Tactical Compensator

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™ Tactical Compensator incorporates vast R&D resources from years of testing low concussion devices but also adds to it with new technology.  Billet machined from 2 pieces of 17-4 Stainless steel, this device is laser welded together to provide the largest possible internal expansion chamber which reduces concussion as effectively as possible. The benefits of laser welding include a much deeper penetrating, evenly distributed precision weld to greatly enhance the strength of the attachment bond, while also creating a more polished appearance to the exterior of the muzzle device. This design would be impossible to manufacture in a single CNC cut work piece. The flash hider front cap was derived and applied from the high performance RECCE suppressor flash hider front caps while adding a thick erosion resistant face to ensure extremely long service life.  CNC machining this device in two pieces is more expensive and time consuming than a single piece device for both machine time and human handling however no corners were cut to produce the optimal design.

    Shims that came with it worked well and timed it perfectly to setup the Dual Lok on the can. Well built and looks BA!

    Solid piece of kit that was easy to install. Getting it "timed" correctly to my barrels was a little time consuming but, everything turned out just fine.

    Awesome muzzle device

    Published by Michael Maggio on 12th Jan 2023

    I rebuilt my rifle and decided to try out this muzzle device. It’s excellent at mitigating recoil, it virtually eliminates horizontal and vertical recoil and the only movement I felt pushing back was the bolt and buffer moving in my rifle. It’s like magic.

    Crazy recoil reduction and seems to cut flash out pretty well too

    Published by Michael Maggio on 11th Jan 2023

    I installed this on my rifle and when combined with a my mid length gas system and A5 buffer there was virtually no recoil. You can actually feel the buffer move in the rifle because it eliminates horizontal and vertical movement it’s awesome.

    I work at the company. But screw it. I can review things too. This is a bad ass muzzle device. It's my favorite one. the design features and welding are amazing. Anyone who says otherwise is high. This is gucci ass kit. The Dual lok mount is also amazing. Well done Austin.

    Dual Lok - Tactical Compensator

    Published by Justin G on 27th Jul 2022

    I recently purchased Griffin armimmence duelock suppressor adapter, griffins stealth flash hider, and the Dulock tactical compensator. I am very pleased with all three products and am extremely impressed by the door lock concept. The door lock attaches up very nicely and the stealth flash hider mitigated all if not most of flash from my 11.5. I’m thinking about getting a second door lock suppressor adapter so I can switch From my silencer Ko adapters. The tactical compensator looks awesome and has impressive flash and recoil and concussion mitigation. I like that the tactical compensator acts as a sacrificial first baffle.
