GRIFFIN Dual-Lok Flash Suppressor .30 Cal 3/4x24 - Premium Muzzle Device for Precision Shooting

The Griffin Armament Dual-Lok Flash Suppressor in .30 cal, 3/4x24 thread is a lightweight muzzle device engineered for shooters who demand precision and reliability without unnecessary bulk. This flash suppressor serves as the muzzle-mounted component of Griffin's Dual-Lok quick-disconnect system, pairing with the Dual-Lok HUB Mount to create a suppressor interface with exceptional repeatability and security. Built from 17-4 PH stainless steel with a QPQ nitrided finish, it's designed for serious shooters who run suppressors and need a mounting solution that stays put and returns to zero, shot after shot.

What sets the Dual-Lok system apart is its engineering: the flash suppressor features 60 machined mounting position splines that work in tandem with the mount's two locking positions, offset by 3 degrees, to deliver 120 effective engagement points. This redundant locking geometry eliminates timing requirements and shims—install it, tighten it, and trust it. The three flash-suppressing tines incorporate anti-resonance features to minimize the ringing that can occur under sustained fire, keeping your shooter experience cleaner and reducing back-pressure harmonics. At just 2.4 ounces, this muzzle device is substantially lighter than most competitive flash suppressors, reducing overall suppressor system weight so your rifle remains balanced and responsive.

The Dual-Lok design is wear-free and contains no consumable parts, so you won't be replacing springs or locking collars. The QPQ finish resists corrosion and wear, and the taper lock interface ensures the kind of accuracy and security that makes sense on a precision rifle. Whether you're running a 30-caliber rifle at the range, in the field, or on a precision shooting platform, this muzzle device delivers the stability and confidence a quality suppressor mounting system demands.
