The present disclosure relates to a device for firing a projectile. The device comprises a stock, at least two elastic members, two levers symmetrically arranged on opposite sides of the stock, a first flexible element connecting the two levers with each other and intended for pushing the projectile during the firing, and a loading arrangement for shifting the device from a rest condition to a loaded condition. The two levers are movable with respect to the stock between a first position when the device is in the rest condition and a second position when the device is in the loaded condition; the two levers are operatively connected with the at least two elastic members for correlating a movement of the two levers between said first and second positions to a variation of deformation of the at least two elastic members. and vice versa. The loading arrangement includes a first loading member configured to receive a foot of a user, and a second loading member protruding from the device and configured to rest against a support surface for supporting the device during the loading phase. One between said first and second loading members is associated with the stock and the other between said first and second loading members is movable together with the two levers. A distance between the first loading member and the second loading member is lower in the loaded condition than in the rest condition. |
