Laser bullet training
A laser bullet is a dry fire training tool that uses a device in the shape of a bullet that emits a split-second laser pulse. The laser bullet〔"Laser Bullet" can also refer to a boresighting device. See (Red-i-Laser SFS Short Flash System ); (Laser Bullet )〕 is inserted in the chamber of the weapon and activated when the trigger pulled. The point of impact of the laser dot, compared to the shooter’s point of aim, shows errors in technique. Laser bullet training allows repeated practice without the need for live ammunition or range facilities.
== Background==
Firearms training requires time, money, and range facilities. To learn the basics of marksmanship, a user must expend hundreds of rounds of ammunition, often at a remote location. And because marksmanship is a perishable skill, even the most advanced users must practice regularly, sometimes daily, to maintain proficiency.
But this does not happen often. For example, many U.S. police officers qualify with their weapon approximately three times per year.〔Based on various sources. See (Officer Forums ); (Police Mag ); (''Daily Nebraskan'' )〕 Compare this to the practice required to maintain the pistol-shooting standard of the US Navy SEAL DEVGRU commando team, where each unit member fires an average of 500 rounds per day during every day of training.〔Richard Marcinko, ''Rogue Warrior'', Pocket Books, New York, 1992.〕 Accordingly, studies indicate that, during an actual shooting incident, the average police officer in the United States scores one hit for every six shots fired. This is a 17% proficiency rate. By comparison, with little or no training, criminals have a 10% proficiency rate.〔Morrison, Greg. (2002). "Police Firearms Training Survey: Preliminary Findings" Paper presented at the annual meeting of the Academy of Criminal Justice Sciences, Anaheim, California, (March).〕 Apparently, maintaining marksmanship proficiency requires regular training.
To address this issue, some firearms users engage in “dry-fire” training, in which the weapon is repeatedly aimed and dry-fired, meaning the trigger is pressed without a bullet in the weapon. However, the ultimate success of dry-fire training – increased accuracy – cannot be assessed until the user fires live rounds at a gun range.
