FR2493501A1 - Counterweight for compressed air pistol - is embedded inside upper tilting body and held by single screw in existing hole to alter centre of gravity - Google Patents

Abstract

The counterweight is for a compressed air pistol. It is embedded in the front part of the upper tilting body of the weapon and is fixed at one end by a single screw going through the body in an existing hole. The counterweight is completely invisible and completely embedded so does not detract in any way from the appearance of the weapon. The weight may be approx. 40 grammes and alters both the balance and centre of gravity of the weapon.

Description

b) c) a)
ADAPTABLE CONFORMER FOR AIR GUN
The present invention relates to compressed air pistols of the 604 type FAS brand made in Italy and distributed in France.

The pistols 604 as proposed are of a lower weight than the drone of existing ares of the same manner.

Shooting with these competition weapons requires great stability and the greatest immobility for the arm carrying the weapon. In almost all cases, users must ballast the weapon by adding balancing weights whose attachment to the weapon is complicated and often impractical for the instructor.

The adaptable counterweight according to the invention makes it possible to avoid these drawbacks. I1 is associated with the gun, fie at the front by a hexagon socket screw whose head remains outside.

 The balancing mass these inside the tilting carcass which forms the top of the weapon; the mass is completely invisible, not changing the aesthetics and the functioning of the weapon.

This mass is adaptable on the weapon in less than a minute by tilting the upper carcass as for loading, placing the mass at the front, engaging and tightening the screw in the mass through the carcass by an existing hole on the front .

The weapon being thus equipped with this 40-gram trap offers a different balance, the center of gravity and the weight being more pronounced in the front, increase the stability and decrease the harmful reactions and vibrations at the start of the shot.
