The TMP Wylde556-L Black titanium suppressor is the 9-baffle Long model from Texas Machine Parts, built from Grade 5 titanium (TMP part no. W556LB). It is a 5.56 NATO can with a 0.28-inch bore, built for 5.56-class rifles. It measures 8.3 inches long and 1.6 inches in diameter and weighs 12 ounces, with a black C-Series Cerakote finish on the outside. TMP designed the baffle system to reduce back pressure and backflow, and a 1/2×28 direct thread hub comes in the box. It is the longest Wylde 5.56 can, which TMP describes as a favorite with bolt-gun shooters chasing maximum sound reduction.
