A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'. The channels behind the grease nipple lead to where the lubrication is needed.
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. [13] The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun , but was cheaper to mass produce and lighter, at the expense of accuracy. [ 13 ]
Light machine gun: a class of machine gun often defined as being designed for carry and use by a single operator and firing the same intermediate-power cartridge as other soldiers in a unit. Live fire exercise or LFX : Any exercise that simulates a realistic scenario for the use of specific equipment.
A dangerous situation can occur when a chambered round fires when the firearm is out-of-battery (called an out-of-battery discharge). The cartridge casing is not sufficiently strong to contain the pressure of firing by itself; it relies on the walls of the chamber and the bolt face to help contain the pressure.
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
Unlike single-shot firearms, which can only hold and fire a single round of ammunition, a repeating firearm can store multiple cartridges inside a magazine (as in pistols, rifles, or shotguns), a cylinder (as in revolvers), or a belt (as in machine guns), and uses a moving action to manipulate each cartridge into and out of the battery position ...
Similar to the American M3 submachine gun, the PAM submachine gun was made entirely of stamped sheet metal. [3] However, instead of the .45 ACP cartridge used in the M3, the PAM used the smaller 9×19mm Parabellum cartridge. This may have also been the reason that the PAM-1 was nearly a pound lighter than the M3. [3]
The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury. Additionally, there is at least one known case of deliberate self-injection with a grease gun. [2]
