Gun Butter LITE Pen Oiler 1/4oz. 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 our good friend (StuffsnPews) across several Fowler Industries Vanta 9s Glocks Sub-Machine Guns Walther PDPs and numerous AR-15 variants. You can expect the same great non-toxic benefits as our standard lubricant while shredding your local USPSA match. Being less viscous you also gain the benefits of all the more reliability in arctic conditions.
