To put lock time and bullet dwell time in perspective; the lock time of most conventional bolt action rifles varies between 2.6 and 9.0 milliseconds, while after cartridge ignition most rifle bullets travel through a high powered rifle barrel bore in 1.0 to 1.5 milliseconds. Mechanical bolt-action rifle trigger systems with a sub 2.0 ...
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
Metallic cartridges package projectile, propellant and primer together. They are initiated by striking with a firing pin or striker that passes through the breechblock.Early metallic-cartridge, single-shot breechloading rifles, such as the British Snider–Enfield model 1866 and the American Springfield model 1873, continued to use side-mounted hammers and lock mechanisms that differed little ...
The lock time of conventional bolt-action rifles is usually around 2.6 to 9.0 milliseconds. [1] For example, the SIG Sauer 200 STR / SSG 3000 has a relatively short lock time of 2.4 ms. [ 2 ] Firearm mechanisms utilizing a hammer are known for having long lock times since the hammer becomes an extra moving part contributing to a longer lock time.
A trigger disconnector captures the hammer in the cocked position after a shot has been fired, even if the trigger is held to the rear as the gun cycles. This ensures the gun can only fire in the semi-automatic mode, as the trigger needs to be released to 'reset' and have the disconnector release the hammer back to the trigger sear.
The result was Harry Sefried's two-lever Micro-Motion trigger, introduced in 1951. Adjustable for pull-weight between 2.5 and 6 lbs, [note 6] and travel between .030 and an almost imperceptible .003 inches, the Micro-Motion was an instant success, and considered the new state of the art in match rifle trigger locks.
For double-barreled guns that use one shotgun barrel and one rifle barrel, see combination gun. Double action revolver: A revolver whose trigger performs two actions, firing the round, and cocking the hammer. Double rifle: A rifle that has two barrels, usually of the same caliber. Like shotguns, they are configured either in over-and-under or ...
A break action is a type of firearm where the barrel(s) are hinged and can be "broken open" to expose the breech. Multi-barrel break action firearms are usually subdivided into over-and-under or side-by-side configurations for two barrel configurations or "combination gun" when mixed rifle and shotgun barrels are used.
