Ten years of muzzle device research, design, testing, and manufacturing resulted in our latest revision FlashComp. With winning features of our Hammer Comp integrated, the new flash comp adds an additional sacrificial baffle, offers better flash signature, and is reduced in weight!

The Griffin Armament Gate-LOK™ muzzle devices interface with Gate-LOK™ suppressors (M4SDKM4SD2, 30SD, and 30SDK) as well as the QD Blast Shield.

The Gate-LOK™ Flash Comp optimally combines the functions of three traditionally separate classes of devices- Muzzle Brakes, Tactical Compensators, and Flash Suppressors. The Gate-LOK™ Flash Comp achieved a perfect 5 out of 5 in National Tactical Officers Association testing to achieve the rare, coveted, NTOA Gold seal of approval granted to devices which achieve perfect evaluations.

Compatible with the M4SD series Gate-LOK™ suppressor interface. The Flash Comp provides a sacrificial baffle to increase the service life of your silencer. It is also pre drilled, and 2.25" length for 14.5" to 16" permanently attached, Non-SBR, M4 carbine builds. For optimal flash reduction we recommend 14.5" or longer barreled host weapons. Extreme durability, low concussion, flash and recoil reduction are the wave of the future- the Flash Comp provides an elegant solution to a complex problem. Includes shim set for mounting to suppressor. An over-travel stop is no longer included with this muzzle device because the device features an over-travel stop machined into the device itself.

    It's a flash hider with a sacrificial baffle for a gate-lok suppressor. Boom, done.

    Outstanding device

    Published by Benjamin Bauman on 21st Oct 2022

    I can’t say enough about how much I like this device. I now own three of these and one other muzzle device from Griffin to use with my 30 SD-K. They’re easy to install correctly, they come with everything you need for install, and their performance is flawless. I would absolutely recommend this whether it’s to work in conjunction with a suppressor or not.

    Best fit with griffin blast shield

    Published by Lim K. on 11th Apr 2022

    The reason I bought this is because I have a griffin gen2 blast shield. When the gunsmith put it on , it’s fits perfectly and snuggled and the quality is excellent. Can’t wait to take it to the range. So far I’m very happy.

    This was the perfect replacement for the factory flash hider, made it the flattest shooting rifle I own. Also perfect for my to utilize a suppressor as well as my bayonet!

    Excellence

    Published by Mike w on 15th Apr 2020

    The flash comp is amazing! Hands down one of the most well rounded muzzle devices I’ve ever used. Performs very good. Just don’t put it on a barrel shorter than a 14.5” unless you hate your hearing... or are running a silencer 99.5% of the time, cause this bitch is loud
