GRIFFIN Dual-Lok EZ Brake 30CAL 1/2x28 Muzzle Device

The Griffin Armament Dual-Lok EZ Brake is a 30-caliber muzzle device engineered for shooters running Griffin's Dual-Lok suppressor system. Built from 17-4 PH stainless steel and finished in black nitride, this brake serves dual purposes: it anchors your suppressor with repeatable, rock-solid lockup, and it tames recoil with three radial slots that work whether you're shooting unsuppressed or prepping for a can. The EZ Brake is one of the lightest mounts in the Dual-Lok lineup at just 2.5 ounces, which means less weight on your barrel and a more responsive rifle—a real advantage if you're hunting or running precision drills at distance.

Installation is straightforward: the 1/2x28 thread pattern fits standard 30-caliber rifles, and unlike some brakes, this one requires no timing. A 13/16-inch socket wrench is all you need to get it torqued down. Once installed, the taper design and retention ring ensure minimal point-of-impact shift, so you won't chase zero after swapping between suppressed and unsuppressed shooting. That's the kind of consistency that matters when you're zeroed in for a hunt or competition.

If you're building a 30-caliber rifle around Griffin's Dual-Lok 5, Dual-Lok 7, HRT-556, or HRT-762 suppressors, this brake is the natural starting point. The durability of 17-4 PH stainless means it'll handle years of field use without corrosion creep, and the slim profile keeps your rifle's aesthetics intact while delivering real recoil management.

Frequently Asked Questions

What Dual-Lok suppressors does this brake work with?

The EZ Brake interfaces with all Dual-Lok series silencers, including the Dual-Lok 5, Dual-Lok 7, HRT-556, and HRT-762.

Do I need to time this brake during installation?

No. The EZ Brake requires no timing—install it with a 13/16-inch socket wrench and you're done.

Will this brake cause my point of impact to shift when I add or remove a suppressor?

The taper and retention ring design is engineered for solid lockup and minimal, repeatable point-of-impact shift, so zero drift between suppressed and unsuppressed shooting should be minimal.

Is this brake suitable for field hunting or just range use?

The 17-4 PH stainless steel and black nitride finish provide durability for field conditions, and the lightweight design (2.5 ounces) is ideal for hunters who value reduced weight and barrel responsiveness.
