Abstract
Abstract It comprises a shock detector controlling the release of the laser as well as a part 7 limiting the stroke of the percussion system to a value such that its impact on this part will be sufficient to release the laser through the intermediary of the detector but insufficient to cause vibrations of the weapon leading to oscillations of the laser beam.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
Device for the transformation of a bullet shooting weapon into a laser training weapon, characterized by the fact that it comprises a housing for a shock detector controlling the release of a laser beam as well as a part carried by said housing and limiting the stroke of a percussion system of a said weapon to a value such that the impact of such a percussion system on said device will be sufficient to release such a laser beam through the intermediary of such a detector but will be insufficient to cause vibrations of the weapon leading to oscillations of such laser beam, the housing being parallelepipedic and having dimensions such that it is adapted to be wedged into a fire groove of a breech of a rifle to reduce the stroke of a percussion member of said rifle during the release of the shot.

Claim 3
Dependent Claim
23 words
Device according to claim 1, said part being adjustable in position relative to said housing to modify the stroke of the percussion system.
Claim 4
Dependent Claim
169 words
Device for the transformation of a bullet shooting weapon into a laser training weapon, characterized by the fact that it comprises a housing for a shock detector controlling the release of a laser beam as well as a part carried by said housing and limiting the stroke of a percussion system of a said weapon to a value such that the impact of such a percussion system on said device will be sufficient to release such a laser beam through the intermediary of such a detector but will be insufficient to cause vibrations of the weapon leading to oscillations of such laser beam, the housing comprising a fore portion having the shape of the cartridge chamber of the weapon, the housing being provided with a cutaway portion which in service position, permits avoiding any interference between the housing and an extractor of the weapon; said part extending within the space in which the displacement of a percussion system of said weapon takes place during the release of the shot.
