GRIFFIN Dual-Lok Flash Suppressor .45 Caliber 5/8x24 Thread

The Griffin Armament Dual-Lok Flash Suppressor in .45 caliber with 5/8x24 threading is a lightweight muzzle device engineered for shooters running suppressor-ready ARs and other .45 platforms. Unlike traditional flash hiders that simply redirect blast, this suppressor-compatible muzzle device integrates into Griffin's patent-pending Dual-Lok quick-detach system—a wear-free mounting platform that locks your suppressor in place with 120 effective positions and virtually zero point-of-impact shift. Built from 17-4 PH stainless steel with a nitrided QPQ finish, it handles full-auto use, sustained fire, and harsh field conditions without degradation.

The Minimalist Stealth design prioritizes weight and shootability. At just 2.4 ounces, it's substantially lighter than competing flash suppressor mounts, keeping your barrel rise minimal and your gun faster to track in rapid-fire scenarios. The three flash-suppressing tines feature integrated anti-resonance geometry to eliminate pinging and ringing—noise and vibration that can throw off your shot or announce your position. Because it's part of the Dual-Lok system, there's no timing, no shims, and no guesswork at installation; the taper lock interface ensures security and accuracy right out of the box.

Whether you're running a dedicated .45 upper, an Uzi-platform host, or another .45 shooter, this muzzle device is designed to be a permanent, low-friction partner to a Dual-Lok suppressor hub. The wrench flats make installation and maintenance straightforward, and the nitrided stainless steel construction resists corrosion in wet climates and salt environments. No consumable parts to replace—it simply works.

Frequently Asked Questions

Is the Dual-Lok Flash Suppressor compatible with Griffin Armament suppressors?

Yes. This muzzle device is part of Griffin's Dual-Lok quick-detach system and is designed to work with Dual-Lok HUB mounts. The 60 machined splines on the suppressor and the two phased locking positions on the hub create 120 effective mounting positions for a secure, tightly locked suppressor mount with minimal POI shift.

Does this muzzle device require timing or alignment?

No. The Dual-Lok Flash Suppressor requires no timing, shims, or alignment during installation. The taper lock interface handles positioning automatically, making setup straightforward and repeatable.

What makes this flash suppressor lighter than competitors?

The Minimalist Stealth design uses a streamlined three-tine configuration and is machined from 17-4 PH stainless steel to optimize weight without sacrificing durability. At 2.4 ounces, it reduces overall suppressor system weight and improves barrel responsiveness compared to heavier muzzle devices.

Will the Dual-Lok system shift point of impact when I install or remove the suppressor?

The 120 effective locking positions and taper lock interface are engineered to ensure minimal POI shift. The wear-free mounting system locks the suppressor solidly with no play, providing consistent shot placement between suppressed and unsuppressed firing.
