Griffin Armament Gate-Lok Closed Tine Flash Hider 5.56mm 1/2x28

The Griffin Armament Gate-Lok Closed Tine Flash Hider is a purpose-built 5.56mm muzzle device designed for hard-use rifle platforms. Machined from 17-4 PH Stainless Steel for exceptional durability and heat resistance, this flash hider uses a closed tine geometry that is free of wear-prone surfaces that can degrade performance over time on traditional open-tine designs.

The 1/2x28 thread pitch makes it a direct fit for standard 5.56mm NATO barrels, and the ambidextrous QD mount is purpose-built to interface with Griffin Armament Gate-Lok suppressors. Precisely calculated porting compensates for muzzle rise, while the closed tine profile suppresses flash signature for a cleaner low-light and night-vision profile.

Built for duty rifles, suppressor-ready carbine builds, and any 5.56mm platform that needs a rugged, service-grade flash hider, the Gate-Lok Closed Tine delivers proven Griffin Armament performance in a compact package.
