Griffin Armament
The Griffin Armament Dual-Lok 2.25" Flash Suppressor is a precision muzzle device engineered for 7.62mm AR-platform rifles and designed to work as the muzzle end of Griffin's proprietary Dual-Lok quick-detach suppressor mounting system. If you run a suppressor on your rifle, the Dual-Lok system solves two persistent problems: repeatability and mounting security. The muzzle device itself features 60 machined spline grooves that work in concert with the Dual-Lok mount's two locking positions (offset by 3 degrees) to deliver 120 effective engagement points. The result is a rock-solid, wear-free suppressor connection that doesn't shift point of impact or require consumable parts.
The "Stealth" designation reflects Griffin's focus on flash performance. A three-prong design with anti-resonance flutes suppresses muzzle flash effectively while eliminating the ringing or pinging that can occur under sustained fire. Built from heat-treated 17-4 PH stainless steel and finished with QPQ nitride treatment, this muzzle device is ready for hard use in any weather. The wrench flats allow straightforward installation, and the device comes pre-drilled and ready for pinning and welding on 14.5" barrels that need to meet 16" overall length requirements.
This is a purpose-built component for shooters committed to suppressed shooting on the AR platform. Whether you're running it on a dedicated precision rifle, a hunting AR, or a do-it-all duty gun, the Dual-Lok system delivers the precision mounting you'd expect from high-end optics, applied to your suppressor. No timing, no shims, no guesswork.

The Dual-Lok 2.25" Stealth Flash Hider works exclusively with Griffin Armament's Dual-Lok suppressor mount. The spline grooves on this muzzle device are designed to interface with that proprietary QD system.
Yes. The muzzle device is pre-drilled for pinning and welding and is suitable for 14.5" barrels that need to meet 16" overall length requirements.
The product is the muzzle device only. The Dual-Lok suppressor mount is sold separately and is required to use this device as part of the quick-detach system.
No. The 120 effective locking positions, created by the 60 spline grooves on the muzzle device and the two offset locking positions on the mount, provide extremely low POI shift. The system is designed for repeatable, precise mounting without zero shift.
