Gun Butter LITE is the newest formula in the pantry. This less viscous lubricant appeases the tight tolerance 2011s and prioritizes lack of carbon build up while sacrificing a hair of durability and adhesion. This formula has been tested over a year by (@StuffsnPews) across several Fowler Industries Vanta 9s, Glocks, Sub-Machine Guns, Walther PDPs, and numerous AR-15 variants.
