Product Overview
Initially designed for elite HRT unit’s, Griffin Armament’s HRT-556™ model is the shortest addition to the DUAL-LOK® family of suppressors. The latest version HRT-556™ G2 Suppressor features an improved low-profile flash hider endcap that works in conjunction with the ECO-FLOW™ baffle stack to reduce gas backpressure and improve cyclic performance of the host firearm. Other notable improvements incorporated into the HRT-556™ G2 include an improved, lower backpressure ECO-FLOW™ baffle stack, and a thicker blast baffle to increase durability vastly over the already incredibly robust G1 HRT-556™.
The HRT-556™ features the patent pending DUAL-LOK® mounting system, an accurate, robust, reliable, and wear free system with robust muzzle device support. The suppressor itself was designed to have minimal flash signature, POI shift, and gas blow back, coupled with maximum strength, durability, and high sound signature reduction performance.
Baffle technology for this product is linked to a recent Griffin patent and aggressive 4 month R&D program, and a second high durability R&D program targeting reduction of cyclic rate increase, making the suppressor host firearm operating system more reliable and less affected by the suppressor, reducing the contamination of breathing air in the vicinity of the operator’s face compared to previous technology. The patented low profile flash suppressing end cap further adds performance to the low flash baffle system.
DUAL-LOK® suppressors are machined in Griffin’s Watertown Wisconsin facility by freedom loving Americans.
