The next gen PDW .300 Blackout K silencer is here! Built true to the GQ Armory design ethos, the Onyx K was developed to be the ultimate lightweight, compact, and QUIETEST PDW silencer for its size. Developed with Otter Creek Labs, this silencer is intended specifically for .300 blackout and delivers amazing sound performance given it’s compact size and weight. Constructed of full grade 5 titanium, this silencer weighs in at a mere 8.4 oz and is only 6″ long. Forget cheap cerakote that scratches easily, each Onyx K comes coated in premium DLC (Diamond Like Coating) for it’s superior scratch and temperature resistance, but also beautiful finish. The Onyx-K is full auto rated for .300 blackout and can handle up to .300 WM with a responsible firing schedule, though we highly recommend this silencer for .300 blackout because that is what we developed it for. Each silencer ships standard with your choice of a titanium 5/8×24 direct thread mount with taper or a titanium Atlas Ti (Q Plan B style) mount for use with taper fast attach muzzle devices like the Q Cherry Bomb (what we use on our guns), Rearden MFG, and Liberty Precision units. We use the industry standard 1.375×24 internal thread which allows for the flexibility to run whatever attachment method you prefer.
