GRIFFIN Dual-Lok Flash Suppressor 30CAL 18x1RH - Precision Muzzle Device

The Griffin Armament Dual-Lok Flash Suppressor in 30 caliber with 18x1 right-hand threads is a precision muzzle device purpose-built as the front end of Griffin's innovative QD (quick-detach) suppressor mounting system. If you're running a suppressor-ready rifle and want rock-solid suppressor mounting with minimal POI (point of impact) shift, zero timing fuss, and genuinely lightweight engineering, this flash suppressor is the foundation that makes it work.

The Dual-Lok system's genius lies in its dual locking positions machined 3 degrees out of phase—a design that creates 120 effective mounting positions across the suppressor mount's 60 machined splines. That redundancy means your suppressor locks down tight and repeatable every single time you mount it, with virtually no point-of-impact shift between attachments and removals. Built from 17-4 PH stainless steel with a QPQ (nitrided) finish, this suppressor device resists corrosion and wear in the field without eating up consumable parts. At just 2.4 ounces, it's lighter than most competitive flash suppressor mounts—a real advantage if you're building a rifle where every ounce counts, whether you're hunting, running a precision rifle, or managing recoil on a short-barreled setup.

The three anti-resonance flash-suppressing tines are engineered to prevent that annoying pinging that can ring out under fire. The ⅜" wrench flats make installation straightforward, and because this muzzle device requires no timing or shims, you can swap suppressors and get consistent performance immediately. Utility patent pending on the Dual-Lok design means you're running cutting-edge mounting technology that's wearing-free and built to last.

Frequently Asked Questions

What suppressor mount system does this flash suppressor work with?

The Dual-Lok Flash Suppressor is designed to integrate with Griffin Armament's Dual-Lok Hub Mount as part of their QD suppressor system. The suppressor mount attaches to this muzzle device via the 60 machined splines.

Do I need to time or shim this muzzle device?

No. The Dual-Lok Flash Suppressor requires no timing or shims. Install it on your barrel and mount your suppressor—no alignment guesswork or gunsmithing needed.

Will my point of impact shift when I remove and remount the suppressor?

The Dual-Lok system's 120 effective locking positions ensure a tight, repeatable mount. POI shift is extremely minimal between mount and dismount cycles, which is critical for precision shooting and hunting applications where consistency matters.

What's included with this muzzle device?

You receive the Griffin Dual-Lok Flash Suppressor with 18x1 right-hand threads. It is designed to work with the Griffin Dual-Lok suppressor mount, which is sold separately. No additional parts or consumables are required for installation or operation.
