Timer padlock4/24/2023 Not only lock time determines how long it takes from when the trigger has been activated until the bullet has left the barrel. Remington's Model 700 EtronX electronic firing circuit achieves a two orders of magnitude reduction compared to the standard Remington 700 rifle mechanical trigger mechanism. The lock time for an electronic firing circuit with electric ignition of a cartridge can be expected to be around 27 microseconds (0.027 milliseconds). At very low lock times the dwell time of the bullet or pellet becomes the most influential element. Electronic trigger systems are mostly found in high-end match arms and can reduce action time by about 90% or one order of magnitude. To reduce lock time, electronic trigger systems can sometimes be fitted instead of mechanical trigger systems. Olympic champion Jin Jong-oh with his Steyr LP10E match air pistol featuring an electronic trigger system competing during the 2012 Olympics On hammer fired firearms, a more lightweight hammer and a more powerful hammer spring can also shorten the lock time, but a hammer fired firearm will still have a noticeably longer lock time than mechanisms without a hammer. More powerful springs are used to further increase the firing pin velocity for further decreasing the lock time, as well as increase reliability since the new firing pin has less mass. ![]() While ordinary firing pins are usually made of steel, speedlock firing pins are often either made of titanium or a mix of steel and aluminium, which in some cases can reduce the weight of the new firing pin to near half of the original. These kits reduce the lock time compared to the factory rifle by using a lighter firing pin and more powerful springs. Firearms with an electric primer can reach lock times close to zero milliseconds.Īftermarket part kits are available for several production rifles under names such as known as "speedlock". For instance, the mil-spec AR-15 and HK416 triggers have a lock time around 10 ms. 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. For example, the SIG Sauer 200 STR/ SSG 3000 has a relatively short lock time of 2.4 ms. The lock time of conventional bolt-action rifles is usually around 2.6 to 9.0 milliseconds. Important mathematical design parameters taken into consideration is the spring constant (stiffness), firing pin weight as well as the weight of any other moving parts and length of movement. The lock time can be measured electronically, but is often instead calculated mathematically by the manufacturer. Shooters can therefore tend to experience better precision using firearms with a shorter lock time, and short lock times are especially sought after for shooting competitions which require high precision on small targets from unstable positions, such as the standing offhand position. A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has left the barrel, a common shooter error which can lead to poor hits or even misses. Lock time or action time refers to the time interval (often measured in milliseconds) from when the trigger of a firearm is activated until the firing pin strikes the primer, and depends on the design of the firing mechanism.
