precision trigger

Precision guided firearms (PGFs) are long-range rifle systems designed to improve the accuracy of shooting at targets at extended ranges through target tracking, heads-up display, and advanced fire control. Inspired by missile lock-on and fighter jet technology, the application of PGF technology to small arms mitigates multiple sources of marksman error including mis-aim, trigger jerk and shot setup miscalculation. PGFs can significantly increase first shot success probability (FSSP) out to extreme ranges of 1,100 meters or more.
PGFs are fully integrated systems consisting of a rifle, networked tracking scope, guided trigger and precision conventional ammunition based on standard caliber bolt action or semi-automatic rifles. Wireless connectivity allows PGFs to integrate with local and wide area networks to provide voice, video and data connectivity to remotely connected devices and systems.Precision-guided small arms prototypes have been developed which use a laser designator to guide an electronically actuated bullet to a target. Another system in development uses a laser range finder to trigger an explosive small arms shell in proximity to a target. The U.S. Army plans to use such devices in the future.In 2008 the EXACTO program began under DARPA to develop a "fire and forget" smart sniper rifle system including a guided smart bullet and improved scope. The exact technologies of this smart bullet have not been released. EXACTO was test fired in 2014 and 2015 and results showing the bullet alter course to correct its path to its target were released.In 2012 Sandia National Laboratories announced a self-guided bullet prototype that could track a target illuminated with a laser designator.In mid-2016, Russia revealed it was developing a similar "smart bullet" weapon designed to hit targets at a distance of up to 10 kilometres (6.2 mi).In 2019, Israel started using a smart scope named Dagger, also known as Pegion, made by SmartShooter, which is based on the SMASH 2000.Air burst grenade launchers are a type of precision-guided weapons. Such grenade launchers can preprogram their grenades using a fire-control system to explode in the air above or beside the enemy.
