The HRT 556 Rifle Suppressor has been specifically designed to have a minimal flash signature, weight, POI shift, and gas blowback, but retain maximum strength, durability, and sound suppression performance. The DUAL-LOK HRT 556 suppressor accomplishes this via the ECO-FLOW baffles that reduce back pressure and increase flow allowing it to make the host firearm more reliable and provide cleaner air to the operator. The addition of the DUAL-LOK mounting system allows the HRT556 to be removed and replaced easily by the end user while maintaining a high degree of accuracy.
