Griffin Armament Dual-Lok Stealth Features The Griffin Armament Dual-Lok Stealth is engineered as a high performance 3 prong flash hider that also doubles as the muzzle device half of Griffin s Dual-Lok QD suppressor mounting system. Time intensive research and development went into the prong geometry to achieve incredible resonance reduction so these flash hiders suppress flash extremely well without ringing or pinging when fired hence the Stealth name. The device integrates 60 machined mounting position grooves which combine with the mount s two locking positions machined 3 degrees out of phase to create 120 effective locking positions. That geometry ensures the suppressor mounts tightly and consistently every time it is installed rather than landing in a loose or randomly oriented position. Built from heat treated 17-4 ph stainless steel and CNC machined to exacting tolerances the Dual-Lok Stealth is then treated with a Melonite QPQ finish for corrosion resistance and a durable low-maintenance exterior. Rated for bullet calibers up to .30 Cal it threads onto a 5/8x24 muzzle and measures 2.34 overall with a 1.07 diameter across the mounting grooves. When the suppressor is installed a spring pushes the locking collar rearward over the splines for a secure lockup without wobble or rattle. For shooters running Griffin Armament s Dual-Lok suppressor system this Stealth flash hider delivers a dependable corrosion resistant muzzle device built for repeated mounting and dismounting.
