Griffin Armament DUAL-LOK HRT-762 Rifle Suppressors

When Griffin Armament designed the DUAL-LOK™ HRT-556™ for elite HRT units, the goal was to deliver a compact, highly durable, low flash, and top tier performing suppressor utilizing the new DUAL-LOK™ active retention system, an often demanded feature by government customers.

Griffin is proud to now complete the HRT lineup with the HRT-762™. This suppressor completes the HRT lineup by providing a highly durable, low flash, 30 caliber model.

The HRT-762™ features the patent-pending DUAL-LOK™ mounting system, an accurate, robust, reliable, and wear free system with robust muzzle device support. The suppressor was designed to have minimal flash signature, minimal POI shift, and minimal gas blowback. These attributes, coupled with maximum strength, durability, and sound performance make the HRT-762™ an unbeatable option in the .30cal suppressor market.

Baffle technology is a lightly modified version of the 4th generation Recce Suppressor baffle system. Tuned ECO-FLOW™ baffles reduce back-pressure, increasing flow, making the host firearm operating system more reliable and improving air quality in the vicinity of the operator’s face. The patented low profile flash suppressor end cap further adds performance to the low flash baffle system.

When we developed the HRT-556™, we brought to market a compact, heavy-duty, high-performance can built on a foundation of extensive R&D. Customers requested a .30cal version and we delivered. The HRT-762™ piggybacks off the developments of the HRT-556™ and provides the same top tier performance in a rugged .30caliber option. The HRT 7 is one of our best performing .30cal suppressors to date. I’m extremely proud of the work our team did on this project, and I’m excited to introduce this suppressor to Griffin’s DUAL-LOK™ fanbase.
