The Griffin Armament Griffin Dual-lok 2.25 Flash Suppressor 5.56 combines advanced dual-lock engineering with a high-performance stealth flash hider designed for rifles requiring precise, repeatable mounting and exceptional resonance reduction. This Stealth Flash Hider 2.25 integrates a 60-groove muzzle device interface that is doubled by the mounts two locking positions, phase-shifted by 3 degrees to create 120 effective locking positions for a rock-solid, no-wiggle fit that minimizes POI shift. The high-efficiency 3-prong design delivers outstanding flash reduction without ringing or pinging under fire, supporting stealth and accuracy in dynamic environments. Crafted from heat-treated 17-4 PH stainless steel and finished with Melonite QPQ, the unit offers durable corrosion resistance and long service life, with an exact 1.07 inch diameter and 2.34 inch overall length weighing just 3.3 ounces. The Dual-lok system is wear-free and requires no consumable parts, featuring a taper lock interface for secure alignment and a pre-drilled option for pinning and welding 14.5 to 16 inch barrels. With precision CNC machining, anti-resonance flutes, and wrench flats on the muzzle devices, this solution enables repeatable, accurate mounting for reliable suppressor performance in demanding field conditions.
