A tripod is a portable three-legged frame or stand, used as a platform for supporting the weight and maintaining the stability of some other object. The three-legged (triangular stance) design provides good stability against gravitational loads as well as horizontal shear forces, and better leverage for resisting tipping over due to lateral forces can be achieved by spreading the legs away from the vertical centre. Variations with one, two, and four legs are termed monopod, bipod, and quadripod (similar to a table).

thumb|400px|right|Illustration of some firearm breechblocks A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge.

An autoloader or auto-loader is a mechanical aid or replacement for the personnel that load ammunition into crew-served weapons without being an integrated part of the gun itself. The term is generally only applied to larger weapons, such as naval weapons, tanks, and artillery; that would otherwise have a dedicated person or persons loading them.

USP-1 or "Tyulpan" (From Russian: Унифицированный Стрелковый Прицел, первый образец, Unifitsirovannyj Strelkovyj Pritsel, pervyj obrazets, "Unified Firearm Sight, first model, GRAU index 1P29) is a Soviet/Russian universal optic sight, used on the AK rifle family (AKMN, AK-74N, AK-74M, AK-101, AK-102, AK-105), the RPK-74N, the PKMN and the PKP "Pecheneg" and is designed for quick-mounting and quick-detaching. Compared with an open mechanical sight, the effectiveness of firing at targets is increased 1.2 to 2 times, and the time taken to conduct a firing session is reduced by 60%. == Design ==
