The Griffin Armament DUAL-LOK OTB 2 Port Muzzle Brake for 7.62mm rifles is a precision-engineered brake designed to tame recoil on magnum and large-caliber centerfire rifles. Built on Griffin's proven Paladin R platform, this muzzle brake delivers measurable recoil reduction while maintaining a clean, professional appearance—the kind of upgrade that transforms how a rifle feels behind the trigger without compromising its lines.
Constructed from 17-4 PH stainless steel and finished in black oxide, the DUAL-LOK OTB is built tough for serious shooters and hunters who demand durability under hard use. The two-piece welded design combines structural integrity with repeatable performance, and the reverse-porting geometry of the Paladin R braking system works to redirect gas flow in a way that actively suppresses muzzle rise and recoil energy. If you run a suppressor, this brake is also compatible with Griffin's SPR and RSTA silencers via the OTB interface, giving you a modular setup that doesn't sacrifice performance.
The brake comes threaded to industry-standard specifications—your choice of 1/2x28 or 5/8x24—and includes a shim set for precise bore alignment and fitment on various rifle configurations. At just over 4 ounces, it won't throw off your rifle's balance, and the polished welds and Griffin laser logo mark a brake that looks as good as it performs. This is no-nonsense equipment for shooters who care about precision and recoil control.

Yes. The DUAL-LOK OTB interface is designed to work with Griffin's SPR and RSTA silencers, allowing you to add sound suppression while maintaining the same mounting system.
This brake is available in 1/2x28 or 5/8x24 threads. The 1/2x28 is common on lighter-recoiling cartridges and some ARs; the 5/8x24 is standard on larger magnum rifles. Verify your rifle's muzzle thread pitch before ordering.
This brake is rated for 7.62mm centerfire rifles (.308 Winchester and similar bolt-action and semi-auto platforms). If you're unsure whether your specific rifle is compatible, contact us with the exact make and model.
The brake ships with a shim set to help achieve proper bore alignment and fit on your specific rifle.
