GRIFFIN Dual-Lok Flash Suppressor 30CAL 5/8x24 - Precision Muzzle Device for Reduced Recoil

The Griffin Armament Dual-Lok Flash Suppressor is a 30-caliber muzzle device built around a patent-pending quick-detach mounting system that prioritizes reliability and repeatability. Threaded 5/8x24, this flash suppressor integrates with Griffin's Dual-Lok hub mount to create a suppressor interface that locks into 120 different positions—a result of 60 machined splines on the device working with the mount's dual locking points, offset by 3 degrees. That precision engineering means your suppressor mounts rock-solid with virtually no point-of-impact shift between install and removal, a real advantage for shooters who swap suppressors or run unsuppressed comparisons at the range.

Built from 17-4 PH stainless steel with a nitrided QPQ finish, the Dual-Lok Minimalist Stealth is purpose-built for shooters who value lightweight systems without sacrificing durability. At just 2.4 ounces, it's among the lightest flash suppressors on the market—that weight savings translates to less muzzle-heavy feel and faster barrel response. The three anti-resonance flash-suppressing tines are designed to minimize the metallic pinging that can occur under rapid fire, and because the system requires no timing or shims, installation is straightforward.

There are no consumable parts in the Dual-Lok mounting interface; the wear-free design means the mount won't loosen or degrade with repeated use. The muzzle device includes wrench flats for easy installation and removal. Whether you're building a precision rifle, a duty gun, or a hunting setup that benefits from a lightweight suppressor-ready barrel, the Dual-Lok Minimalist Stealth delivers the repeatability serious shooters expect.
