They say: Copper Grease is a high performance lead-free anti-seize compound which is designed for application to threads of nuts and bolts prior to assembly to ensure easy release, without damage, even after long periods in adverse conditions. The product is based on a non-melting grease containing a complex blend of heat resistant solids and low shear metals
We say: Apply sparingly to your rifle muzzle thread before attaching a sound moderator and on your shotgun chokes after cleaning.
