The Griffin Armament DUAL-LOK Mini Brake is one of those parts that pulls double duty and does both jobs well. On its own it works as a compact minimalist muzzle brake, but its real trick is serving as the muzzle-side interface for Griffin's DUAL-LOK quick-detach suppressor mounting system. If you're running or planning to run a DUAL-LOK series can, this is the piece that lives on your barrel and gives your suppressor something to lock onto.
The DUAL-LOK system is built around a two-piece setup: this muzzle device plus the DUAL-LOK mount on the suppressor. The brake carries 60 machined mounting grooves, and the mount adds two locking positions machined 3 degrees out of phase with each other. That math works out to 120 effective locking positions, which means you get a tight, indexed lockup no matter where the threads happen to stop. It's the reason Griffin leaned into the DUAL-LOK name.
The standout here is repeatability. The taper geometry seals gases to keep the QD threads clean and forces the suppressor into alignment with the bore, which keeps point of impact shift to a minimum when you take the can on and off. There's no wear-prone ratcheting hardware to fuss over, so the lockup stays consistent shot after shot, gun after gun. That last part matters if you're bouncing one suppressor between multiple hosts.
This 7.62 version is cut for 5/8×24 threads, the standard pitch for most .30-caliber and larger rifle barrels. Griffin machines these from 17-4 PH stainless steel and adds a wear-resistant sacrificial baffle that soaks up blast and extends the service life of your suppressor. Everything is made in-house at Griffin's shop in Watertown, Wisconsin.
Worth noting: this device interfaces specifically with Griffin's DUAL-LOK series suppressors. If you already own or are eyeing a DUAL-LOK can, this brake is the natural match to get it mounted and shooting.
This brake serves as the muzzle-side interface for Griffin's DUAL-LOK series suppressors, including the DUAL-LOK 7, HRT-762, and other DUAL-LOK cans. It is not a universal QD mount, so it pairs specifically with the Griffin DUAL-LOK ecosystem. If you own or plan to buy a DUAL-LOK suppressor, this is the muzzle device that lets you attach it.
The DUAL-LOK design uses 60 machined grooves combined with the mount's two locking positions for 120 effective locking spots, so you get a solid lockup wherever the threads stop. You simply torque it to spec on your barrel. The indexed grooves handle alignment for the suppressor, so you are not chasing a specific clock position.
The taper geometry forces the suppressor into alignment with the bore and the locking collar creates a repeatable connection, which keeps point of impact shift to a minimum. Because there are no wear-prone ratcheting parts, the lockup stays consistent over time. Many users zero once and trust the can to return to the same spot.
This is the 7.62 version cut for 5/8×24 threads, which is the common pitch for .30-caliber and larger rifle barrels. It is built from 17-4 PH stainless steel with a sacrificial baffle to protect your suppressor. Just make sure your barrel is threaded 5/8×24 before ordering.
