Lock time
Improvement of lock time
Aftermarket part kits are available for several production rifles under names such as known as "speedlock". These kits reduce the lock time compared to the factory rifle by using a lighter firing pin and more powerful springs. While ordinary firing pins usually are made out 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. 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. 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 noticeable longer lock time than mechanisms without a hammer.
