Description
The Griffin Armament Gate-LOK™ muzzle devices interface with Gate-LOK™ suppressors (M4SDK, M4SD2, 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).

Just got the stamp for my 30SD after waiting 1-1/2 years. I have a couople of 5.56 rifles that I planned to use the 30SD on, so an extra precision muzzle device was needed. Well made and easily timed with the included shims. Works great on my Tavor with the 30SD.

Great flash hider, quality materials and does an excellent job suppressing the flash. I will be buying more.

I install this device on a 12.5″ AR pistol and have noticed a huge difference in flash signature than the original device I had! A huge improvement plus aestheticcally appealing!

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.

Very nice quality.

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..

Easy to install. Works perfectly with suppressor.

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

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.
