The Loctite 380 "Black Max" is a black, cyanoacrylate adhesive that comes in a 3 g tube. This is what KEL TEC uses from the factory to secure the Collar to the back of the SUB-2000. You really need a strong adhesive like the Loctite 380 "Black Max" to bond the aluminum collar to the plastic trigger assembly since there are no threads for the collar to tighten up against on the firearm. The low viscosity, durable adhesive is great for a variety of applications including bonding metal, rubber and plastic.
