Cocking Handle
The cocking handle, also known as charging handle or bolt handle, is a device on a firearm which, when manipulated, results in the bolt being pulled to the rear, putting the hammer/striker into a spring-loaded ("cocked") "ready and set" position, allowing the operator to open the breech and eject any spent/unwanted cartridge/ shell from the chamber, and then load a new round from the magazine or belt if required. By opening the breech, it also helps the operator to verify that the weapon's chamber is clear of any rounds or other obstructions; to clear a stoppage such as a jam, double-feed, stovepipe or misfire; to facilitate moving the bolt back into battery, acting as a forward assist (but not necessarily); and to release a bolt locked to the rear by a catching mechanism on a firearm equipped with a "last round bolt hold open" (LRBHO) feature. These devices vary significantly between firearms but may occur in the form of a small protrusion or hook from the side of the bo ...

SA80
The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The first prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2020. The A3 variant was first issued in 2018 with several new improvements. The remainder of the SA80 family comprises the L86 Light Support Weapon, the short-barrelled L22 Carbine and the L98 Cadet rifle. The SA80 was the last in a long line of British weapons (including the Lee–Enfield family) to come from the Royal Small Arms Factory, the national arms development and production facility at Enfield Lock, before its weapons factory was closed down in 1988.

Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloves
A glove is a garment covering the hand. Gloves usually have separate sheaths or openings for each finger and the thumb. If there is an opening but no (or a short) covering sheath for each finger they are called fingerless gloves. Fingerless gloves having one small opening rather than individual openings for each finger are sometimes called gauntlets, though gauntlets are not necessarily fingerless. Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens. Mittens are warmer than other styles of gloves made of the same material because fingers maintain their warmth better when they are in contact with each other; reduced surface area reduces heat loss. A hybrid of glove and mitten contains open-ended sheaths for the four fingers (as in a fingerless glove, but not the thumb) and an additional compartment encapsulating the four fingers. This compartment can be lifted off the fingers and folded back to allow the individual f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean Time Between Failures
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation. MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The term is used for repairable systems while mean time to failure (MTTF) denotes the expected time to failure for a non-repairable system. The definition of MTBF depends on the definition of what is considered a failure. For complex, repairable systems, failures are considered to be those out of design conditions which place the system out of service and into a state for repair. Failures which occur that can be left or maintained in an unrepaired condition, and do not place the system out of service, are not considered failures under this definition. In addition, units that are taken down for routine scheduled maintenance or inventory control are not considered within the definition of failure. The higher the MTBF, the longer a system ...
