Griffin Dual-Lok 5 Silencer - Advanced Noise Reduction & Precision Engineering

The Griffin Dual-Lok 5 is a modular suppressor engineered for hunters, precision shooters, and tactical users who demand both effectiveness and reliability from their noise reduction system. Built on Griffin Armament's patent-pending Dual-Lok mounting system, this suppressor delivers a rock-solid connection with minimal point-of-impact shift—a critical advantage whether you're dialing in at the range or afield. At 1.5 inches in diameter and 6.5 inches overall, it strikes a practical balance between noise reduction and handling; add the included Minimalist Brake and you're looking at just 5.1 inches of added length.

Precision manufacturing sets the Dual-Lok 5 apart. The body is laser-welded 17-4 stainless steel with 718 Inconel components, H900 heat-treated and finished in high-temp Cerakote to withstand sustained fire and harsh conditions. The wear-free Dual-Lok mount requires no consumable parts—no babbit inserts to replace, no periodic maintenance—and features 120 effective indexing positions to guarantee a secure fit with zero runout. An ACME thread interface speeds attachment and removal, while a locking ring with three anti-rotation teeth keeps the suppressor seated without accidental loosening.

Acoustic performance is substantial: 135 dB rating on standard rifle configurations and 134 dB in extended setups, with the patent-pending end cap optimized for flash reduction and flow efficiency. The suppressor is rated for full-auto fire, making it suitable for any civilian rifle application and ready for whatever shooting discipline matters most to you. The nitrided collar increases surface hardness and corrosion resistance—important if you hunt or train in wet conditions. At 11.8 ounces, weight penalty is minimal.

Griffin backs the Dual-Lok 5 with a lifetime warranty, reflecting confidence in design and materials. If you want a suppressor that mounts securely, performs consistently, and requires zero maintenance, this is a serious choice.

Frequently Asked Questions

What rifle thread patterns does the Dual-Lok 5 fit?

The included Minimalist Brake is 1/2x28 thread, standard for 5.56mm and .22 caliber rifles. The Dual-Lok mounting system accepts other muzzle devices via ACME thread, so you can use it on different rifles by swapping or adding compatible brakes. If you need a different thread pattern, ensure your brake or muzzle device is threaded to ACME specifications.

What's included with the suppressor?

The Dual-Lok 5 comes with the Minimalist Brake (1/2x28, 5.56mm) pre-installed. A wrench is included for adjusting muzzle devices at the collar.

Does the Dual-Lok 5 work full-auto, or is it semi-auto only?

The suppressor is rated and approved for full-auto fire, so it handles any civilian rifle application without restriction.

Why doesn't this suppressor require baffle replacement?

The Dual-Lok 5 uses a wear-free mounting system with no consumable internal parts. The laser-welded, tubeless design and durable 17-4 stainless and Inconel construction eliminate the need for baffle swaps or maintenance intervals—you mount it and shoot.
