GRIFFIN Dual-Lok Flash Suppressor 30CAL - 14x1 LH Thread

The Griffin Armament Dual-Lok Flash Suppressor is a 30-caliber muzzle device engineered for shooters who want a lightweight, precision quick-detach mounting solution without the hassle of timing or shims. Built around Griffin's patent-pending Dual-Lok system, this flash suppressor threads onto barrels with a 14x1 left-hand pitch and pairs with Griffin's Dual-Lok suppressor mounts to create a rock-solid, repeatable platform for rifle suppressors. If you're running a precision rifle, hunting rifle, or tactical setup where suppressor security and minimal point-of-impact shift matter, this muzzle device delivers the durability and simplicity that serious shooters expect.

What sets the Dual-Lok apart is its 120 effective locking positions. The muzzle device features 60 machined splines, and Griffin's mount employs two locking positions offset 3 degrees to yield 120 total engagement points. That redundancy means your suppressor locks in tight with virtually no wobble—and when you remove and reinstall it, you'll get the same zero, shot after shot. No consumable parts wear out, no springs fail, and no shims or timing adjustments are needed.

Made from 17-4 PH stainless steel with a QPQ (salt-bath nitriding) finish, this flash suppressor resists corrosion and wear in the field. Three flash-suppressing tines feature integrated anti-resonance geometry to dampen ringing under fire. At just 2.4 ounces, it's among the lightest muzzle devices in its class, keeping your rifle nimble and responsive without sacrificing mounting security or suppressor compatibility.
