This is true firearms grease, it was developed to lubricate and protect under the harshest heat, friction and pressures of sustained firing while reducing friction and wear. Its unique formulation is designed to prevent rust and corrosion from rain and moisture in fresh and saltwater environments.

SHOT Show 2016 Lucas Oil

Bryce Curry of Lucas Oil talks about the extensive line of oil and cleaning products now available for firearms. Bryce breaks down the uses of the new products.

Very impressed (bought three more bottles).

Was given a bottle by Gun Smith/ Builder to try. He knows I will be honest and I use some of my firearms hard. Very impressed (bought three more bottles). Easy cleanup (carbon removal). Very little wear if any in early stages of trial. I have NEVER wiped my bolt carrier clean with a towel much less firing pin or bolt. Further test to follow. Will have to see how it holds up to the salt air, heat and humidity on the Texas coast. -Thomas
