The EOTech DCBL 556 black titanium suppressor is a 3D-printed Grade 5 titanium can for an AR-15 or other 5.56 rifle (EOTech part no. EOT-DCBL-556-MB). EOTech built the DCBL line around a vent-forward design that sends gas forward and away from the shooter, cutting back pressure and blowback for cleaner cycling. The body is 7.1 inches long and weighs 13.7 ounces, and EOTech also publishes the working figures with the hub or flash hider fitted: 7.9 inches and 19.6 ounces. It mounts on the standard 1.375-24 HUB thread, so common HUB mounts and adapters fit. This version carries a black high-temperature Cerakote finish.
