KATIX Resistance Bands - Exercise Bands Set of 3 Pcs for Home Fitness, Yoga, Pilates - Resistance Workout Bands for Both Men and Women

I like this Brand . Works great for Ar Barrel Nut Grease!! Not expensive.

The best grease to use for assembly when metal interfaces with metal. Threads and shafts. This tiny container was bought years ago and I still have 3/4 of the container.

Great product to finish my build. Great lube quality and value.

Works great and you get a sticker!

If you either do, or plan to swap just one or a dozen barrels or muzzle devices this is a MUST have. And considering I've assembled at least ten uppers and swapped countless flash riders, muzzle brakes, compensators, and suppressor mounts and have used maybe half of the container, its just pennies per application. A dab on your finger tip at the beginning of the threads, two 180 degrees apart, thread the barrel nut/muzzle device on and off 3 times to ensure that you get a thin film on all threads, and your good to go! No more hot seizure, corrosion, alloy reaction....gone!
