Abstract: Mechanical control shock-absorbent anti-recoil mechanism intended for various fields such as industrial and civil constructions, machine building industry, robotics et cetera, its purpose being to protect against the impact forces, recoil forces or vibrations. The mechanical control shock-absorbent anti-recoil mechanism comprises a mobile holder X, a joint lever and spring mechanism Y and an end holder Z. The mechanical control shock-absorbent anti-recoil mechanism has the role of absorbing and a cancellation of the impact forces and recoil forces, while a mechanical control mechanism K adjust concomitantly and continuously the tension of the absorbent springs and the annulling springs in order to decrease or to annul the impact force.

Abstract: Stock for a recoilless hunting rifle, for medium and large caliber hunting guns, which eliminates the stress produced by the effect of the recoil on the shooter's shoulder, providing at the same time good targeting precision and reduced consumption of bullet cartridges or shot cartridges. The stock has a stock butt and a mechanical anti-recoil module, with fast assembling, and a gun stock resembling the classical gun stocks but without transferring the recoil force to the shooter's shoulder. The recoilless buttstock includes a mechanical anti-recoil module, presented as an assembly having a pair of coupling parts, an elastic mechanism, a fixed support with rollers, an upper guide with a spring, a lower guide with a spring and the case of the stock.
