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.

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.

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.

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.

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.

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.
