Product Overview
The CAT/MOB/A1, aka Mobster, is the quietest 9mm subgun can on the market that we know of (also see PEW Science's MP5 test data). The HUB model allows use of a tri-lug adapter, but be aware, the ubiquitous YHM tri-lug does not fit because of blast baffle geometry. Resilient's lower profile and lighter titanium one is our recommendation, although we need to test out Rugged's new Bixler-style mount.
The HUB can is for some reason not a high priority when it comes to production for CAT, so these don't get made frequently and are almost always on backorder.
