Used this grease for many different components. Works effortlessly on the barrel nut as well as other threaded components. Does not appear to get soiled easily and is easily to apply with syringe. Highly recommended
Sentry HI-SLIP grease lubricates, waterproofs, and prevents rust even in saltwater. All the benefits of oil but stays put will not migrate and protects surfaces in temperatures from -54C/-65F to 343C/650F. Synthetic blend exceeds mil-specs for moly grease. Lubricates and prevents galling on all types of metal including stainless steel, blued metal, titanium and aluminum. Prevents corrosion from salt water, powder residue, and sweat. Concentrated and extremely long lasting - a little goes a very long way.
