Alliance Hobby Airgun Oil - 1 FLUID OUNCE - 4x Crosman Pellgunoil For Less! 1 fluid ounce of genuine Alliance Hobby Airgun Oil. One bottle will last a lifetime. Four times the amount of the ubiquitous Crosman Pellgunoil that I also sell, for less. Safe and recommended for all Crosman CO2 and 10-pump guns (2240 2250 2260 1322 1377 2289 and countless others). Safe for other mfg's CO2 and pumper guns. Great for the tip of your Powerlet (one drop will do ya), o-rings, wear points, etc. Trial tested for years. Easy to use dropper maintains the small amounts that your airguns needs. Remember, too much oil is worse than no oil at all. NOT for use in springers, nitro, pistons, pcp, hpa and other guns.
