Modern paintball guns are more reliable and durable than ever, thanks in no small part to their ingenious designs. But those designs still contain moving parts and essential o-rings and seals that must be clean and lubricated in order to function properly! GOG Greese is a synthetic paintball grease that is an ideal lube for paintball guns requiring grease instead of oil for lubrication, and is the recommended lubricant for all GOG and Shocker paintball guns. Low friction and able to be used in all weather, GOG Greese paintball gun lube helps prevent bolt stick and first shot dropoff and will help ensure o-rings stay lubricated for proper paintball gun function! 1 oz jar.
