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 7.62mm provides high performance mounting options for Griffin Gate-LOK™ Silencers as well as a 30 caliber (7.62mm) interface for the QD Blast Shield. The Flash Comp was made with the same performance features as its 5.56mm counterpart but with a 5/8x24 threaded interface and integral overtravel stop. Pre drilled hole to aid in pinning and welding. The Gate-LOK™ Flash Comp .30cal (7.62mm) is included with the 30SDK silencer. CNC Machined and outside diameter ground from high strength, corrosion and wear resistant, 17-4 precipitation hardened stainless steel, the Gate-LOK™ Flash Comp .30 cal (7.62mm) is black oxide finished. 5/8x24 threads offer compatibility with most 7.62mm firearms on the market.

    Well made product.

    My 30SD finally got out of ATF jail after waiting a year and a half. I wanted an extra mount for future applications before the model became obsolete. Very well made, and the included shim make timing very easy.
