SUB-2000 Collar Adhesive - Loctite 380 "Black Max"
The Loctite 380 "Black Max" is a black, cyanoacrylate adhesive that comes in a 3g 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. This low viscosity, durable adhesive is great for a variety of applications, including bonding metal, rubber and plastic.

Loctite 380 Spec Sheet
Bought this due to having my buffer collar nut come loose on me after shooting a few magazines. Figured I didn't add enough. Now hopefully it will stay in place. Glad MCARBO has this in stock because everywhere else has it for so much more in price.
What can you say it WORKS
A must have for installing your Castle Nut
This stuff is like the Hen's Teeth of Locktite. Good luck finding it anywhere else on the planet at this price. Even Amazon failed me.
You really have got to have this to reinstall your Castle Nut the right way. This is a special Polymer to Metal superglue basically. Works wonderfully. Like Chris says in his video, be careful you don't slop it around. You will not get it clean.
Buy this if you're replacing any internal parts
You'll need this specific glue (per Kel-Tec) if you open the firearm for any reason, like cleaning or upgrades. It's cheaper here than it is on Amazon, and I couldn't find it at any local home improvement or hardware stores.
Use the right stuff.
If you take your Sub 2000 apart to do so internal work, you will need this to put the weapon back together so it is in a safe working condition. Good price and follow the directions and it will go a long way. Store it in a cool place and the shelf life will be good.
needed for properly reassembling your gun
It's more affordable than anywhere else and its just the right amount. Also, it provides the peace of mind that your gun is put back together properly and securely.
Just used it
Not sure how it will hold up, but I feel better purchasing a product specifically for the task of securing the collar vs. thinking Loctite red or whatever would work. So far so good and when I put it on and tightened the collar with the MCARBO armorer's wrench it got tight pretty quickly and created a very small nice even bead where the collar attaches to the gun.
This is basically black Krazy glue and the "proper" Loctite for aluminum to polymer. I made sure I cleaned any oil off of the plastic and the aluminum collar. The stuff dries instantly so be prepared--my receiver tube is black and a bit got onto it and dried up as I wiped off (it didn't fully wipe off)--if you have a silver receiver or non-black plastic--be careful. Not sure if this stuff is easy to get locally so I recommend getting through MCARBO. Also must be stored refrigerated, so it sits next to the eggs--will see how long before my wife notices the tube.
