The Griffin Armament DUAL-LOK 2.25" Flash Suppressor pulls double duty on a 5.56 rifle. On its own it's a serious 3-prong flash hider that tames muzzle flash and cuts down the resonance ping that plagues a lot of open-prong designs. Pair it with a Griffin DUAL-LOK mount and it becomes the front end of a quick-detach suppressor setup, so you're not stuck buying a separate device down the road.
The part that makes the name make sense is the locking geometry. The muzzle device carries 60 machined grooves, and the mount adds two locking positions that sit 3 degrees out of phase with each other. That combination works out to 120 effective locking positions, which means your can indexes tight and repeatable with barely any point-of-impact shift when you take it off and put it back on.
Everything is CNC-machined from heat-treated 17-4 PH stainless steel and finished with a QPQ Nitride treatment for extra surface hardness and corrosion resistance. It threads 1/2×28 and runs 3/4" wrench flats, so installation is straightforward with no timing, no shims, and no crush washer fuss. The taper lock interface is what keeps the mount concentric and secure once it's torqued down.
The mounting system is designed to be wear-free, meaning there are no consumable parts to swap out over time. It's pre-drilled for pinning and welding, so if you're running a 14.5" barrel you can pin this on and hit a 16" overall length. At right around 3.3 ounces and a 2.25" length, it stays out of the way while still doing real work at the muzzle.
If you're building toward a Griffin DUAL-LOK can or just want a flash hider that's ready when you are, this is a smart piece to start with. Buy the device now, add the mount and suppressor when the time comes.
No. The DUAL-LOK 2.25 works as a standalone 3-prong flash hider right on your muzzle. When you're ready to run a can, it becomes the muzzle-side interface for Griffin's DUAL-LOK mount and suppressor, so you can build into the system over time.
It's cut for 1/2×28, which is the standard thread for 5.56 and .223 barrels. It also has 3/4" wrench flats, so you can install it without timing, shims, or a crush washer.
Griffin built anti-resonance features into the tines specifically to fight that. The design cuts down the ringing or pinging you hear from a lot of open-prong flash hiders, which is where the Stealth name comes from.
Yes. It comes pre-drilled for pinning and welding, so mounting it on a 14.5" barrel brings you to a 16" overall length. It's made from 17-4 PH stainless with a QPQ Nitride finish, so it holds up well to that kind of permanent install.
