The Jaguar Silencers CA-Fatty 5.56mm titanium suppressor is a rifle can for 5.56 NATO and .223 Remington hosts (Buktek part no. CAF889TH-SB). Titanium construction keeps weight off the end of the barrel, which a carbine shooter notices on every shot from the shoulder. The rear of the can is threaded 1.375×24, the HUB pattern, so it attaches through a HUB-compatible mount or muzzle device rather than straight to a barrel. Jaguar Silencers is Buktek’s suppressor brand, and the CA-Fatty is part of its Fatty line. It suits range use, varmint hunting and a suppressed home-defense carbine.
