Abstract

A firearm laser training system according to the present invention includes a laser transmitter assembly and a cartridge adapter assembly, while employing modified blank cartridges to simulate firearm operation. The modified blank cartridges each have a quantity of explosive substance sufficient only to cycle the firearm. The laser assembly is configured for attachment to a firearm barrel and front sight and emits a beam of laser light toward a training system target in response to actuation of the firearm trigger. The laser beam is generally in the form of a pulse having a duration sufficient for the system target to detect a beam impact location. The cartridge assembly is disposed within the firearm barrel to adapt the firearm for compatibility with the modified blank cartridges for simulating firearm operation.

Dependent claims

A system employing mock cartridges for simulating operation of a firearm, wherein said firearm includes a frame to receive said mock cartridges, a barrel coupled to said frame and having a gas port disposed toward a barrel distal end to direct gas within said barrel and released from an exhausted cartridge towards said firearm frame to facilitate cycling of firearm operation and a sight disposed along said barrel to facilitate user aim of said firearm, said system comprising:

a barrel assembly for insertion within said barrel and including:
a cartridge member disposed toward a barrel assembly proximal end to engage and secure a loaded mock cartridge within said firearm, wherein said cartridge member is configured to enable gas released from said mock cartridge to pass therethrough and traverse said barrel in response to firing of said mock cartridge;
and
a guide member attached to and extending distally from said cartridge member to direct said released gas traversing said barrel into said gas port to facilitate cycling of firearm operation;
and
a securing member disposed toward a distal end of said barrel to engage and secure said guide member within said barrel during simulation of firearm operation.

A method of employing mock cartridges to simulate operation of a firearm, wherein said firearm includes a frame to receive said mock cartridges, a barrel coupled to said frame and having a gas port disposed toward a barrel distal end to direct gas within said barrel and released from an exhausted cartridge towards said firearm frame to facilitate cycling of firearm operation and a sight disposed along said barrel to facilitate user aim of said firearm, said method comprising the steps of:

(a) inserting a barrel assembly into said barrel to engage and secure a loaded mock cartridge within said firearm and enable gas released from said mock cartridge to traverse said barrel in response to firing of said mock cartridge;
and
(b) directing said released gas traversing said barrel into said gas port, via said barrel assembly, to facilitate cycling of firearm operation.

cartridge securing means for engaging and securing a loaded mock cartridge within said firearm and for enabling gas released from said mock cartridge to pass therethrough and traverse said barrel in response to firing of said mock cartridge;
guide means for directing said released gas traversing said barrel into said gas port to facilitate cycling of firearm operation;
and
securing means for securing said guide means within said barrel during simulation of firearm operation.
