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

This revised generation 3 Gate-LOK™ Stealth Flash Hider provides M4SD sound suppressor end users a high-performance flash suppressor/compensator alternative to compatible A1/A2 Birdcage flash suppressors. The Gate-LOK™ stealth flash hider provides optimal suppressor fit, enhanced flash signature reduction, and reduces muzzle climb. The focus of the Gen 3 revision was to reduce flash as much as possible. Time intensive R&D resulted in a high performance 3 prong flash hider with incredible resonance reduction. These hide flash extremely well and do not ring or ping when fired.CNC machined and outside diameter ground from heat, corrosion, and wear resistant, precipitation hardened, 17-4 stainless steel for maximum durability.

Compatible with the M4SD series Gate-LOK™ suppressor interface.

Includes shim set and over-travel stop washer. This muzzle device is pre drilled for pinning and welding to a 14.5" barrel to achieve a 16" non NFA length carbine.

Over-travel stop tab should be positioned at the bottom of the muzzle device (6 O'clock).

    Reduced Muzzle flash ?

    Published by Stacy Smith on 10th Oct 2023

    Great purchase, this flash hider does exactly what it’s designed to do. I used it in a 6.5 inch CMMG Dissent 5.56, which was like a flash bang prior to using this device. I used this also in conjunction with Griffin’s 30SD can and it worked great. https://youtu.be/BcwXPmJyaaw?si=eGHL9wcEGcniRa38

    Quality Muzzle Device

    Published by Aaron on 20th Apr 2023

    Just a great muzzle device, I installed mine with a #7 accuwasher and 32 ft/lbs of torque. It performs well with or without my Griffin 30 SD-K attached, and locks up wonderfully with the built in over travel stop on the 30 cal can. I'm considering getting a couple more honestly. Also they have cool stickers so that's baller

    Have yet to go out and shoot it but I’m absolutely blown away by the quality and will definitely be buying another soon and more products. My only issue is by tapping it I was able to hear ringing not sure if you will get this ringing when you shoot

    Gate lock stealth

    Published by Robert on 27th Oct 2021

    Great flash suppressor. Minimal flash on a 11.5 Bren, when the qd blast is added, no flash at all. Will be adding more to my rifles..

    3 prong stealth

    Published by PhilM on 29th May 2021

    I've been experimenting with different mounts in my 10.3 build and the first one I tried was the hammer comp (thinking it would perform like a A2) nope, that bad boy was not meant for such a short barrel..... so I tried the stealth and could not be happier with the results , almost zero flash and the concussion is greatly reduced. And if course my m4sd BFD mounts to it nicely as it should.
