The Griffin Armament DUAL-LOK™ HRT 556™ suppressor is a high durability, low flash, high performance, compact, lightweight suppressor. It provides very high sound reduction on short and long barrel 5.56mm duty rifles.

This suppressor is a tube over construction, laser welded Recce 5 Mod 4 core, built in DUAL-LOK™ interface, HRT applicable (shorter) length model. We recently demonstrated this suppressor in Quantico to military weapon systems procurement officers from duty stations all over the world, and their observations and remarks were very positive. It seemed they were especially impressed by the mounting system, and we greatly appreciated the opportunity we were extended to show them the product. A multi-jurisdictional SWAT team recently selected Griffin suppressors and they mentioned they were really impressed with the high sound reduction and light weight of the HRT 556™ suppressors.
