A chamber safety device is configured to be inserted into one or more openings of a weapon, such as the loading/ejection port(s) or barrel of a shotgun, rifle or handgun. When the chamber safety device is inserted into the one or more opening(s), the weapon is not capable of firing and/or being loaded with ammunition due to the fact that no bullet or shell can be inserted into the firing chamber and/or the weapon firing mechanism cannot come in contact with a bullet or shell located in the firing chamber. At least a portion of the chamber safety device is designed to extend outwardly from breach of the weapon and is colored in a high visibility color such that those nearby can visually detect the presence of the chamber safety device inserted in a weapon.

An oil composition including at least three vegetable oils, each vegetable oil being distinct from the other and each having a smoke point above 200 F., wherein the combined volume of the at least three vegetable oils is at least about 25% of the total volume of the oil composition. A method of removing or preventing carbon fouling on a mechanical component of a device, comprising depositing a vegetable oil composition on the mechanical component of the device, wherein the vegetable oil composition comprises at least one vegetable oil having a smoke point above 200 F., wherein the at least one vegetable oil is present in an amount of at least about 25% by volume of the total volume of the oil composition and wherein operation of the device deposits carbon on the mechanical component.

A gun oil composition adapted specifically for the needs and requirements of modern firearms. The gun oil composition improves lubricity and gun performance under normal and extreme heat and pressure, minimizes and largely prevents the build-up of carbon and debris fouling on metal and non-metal components of the firearm, and substantially reduces cleaning time, while providing increased protection against environmental components such as dust, dirt and rust. The gun oil composition can include a base oil having at least a high viscosity index, an oil having at least a medium viscosity index with a detergent additive, a low viscosity penetrating oil, and a sulfurized ester.

A friction preventing apparatus and a method of manufacturing the same are provided. The apparatus includes: a first object; a second object spaced apart from the first object and facing the first object; and a plurality of charged nanoparticles provided on a surface of one of the first and second objects, such that the nanoparticles are disposed between the first object and the second object. A potential difference is formed between the first and second objects. The nanoparticles may be positively charged and may adhere to the first object, and the first object has a potential lower than a potential of the second object. The nanoparticles may be negatively charged and may adhere to the second object, and the second object has a potential higher than a potential of the first object.
