Therefore, this chassis device External with internal movable anchoring systems, positioning and automatic retention system prior to firing for long weapons considerably improves the operation of the aforementioned devices thanks to:

It also allows the trigger to move immediately away from the shooter's finger, minimizing possible "triggers.”
  • the mechanisms of the optical sighting elements of the weapon do not suffer the detrimental movements associated with the different recoils, as they are located on the external chassis, unrelated to the movements generated by the weapon.
  • the spring had to continually forcefully push the check ball, causing premature fatigue.
  • the system can be applied to weapons already built without having to modify any aspect of them, since they are embraced by the sliding rings and these can be attached to the weapon by simple pressure using thyme or taking advantage of threaded holes already present in the weapon , such as the fixing threads to the cylinder head.
  • the system is easier to manufacture, assemble and therefore more economical in cost.
  • the positioning and guidance system does not need maintenance or adjustment. It also does not need lubrication of any kind.
  • the guide grooves are Interior so the system, in addition to being invisible to the user, is more robust to dust or sand and avoids the possibility of finger entrapment or the intrusion of foreign bodies into the system.
  • the positioning and guiding system is based on an elastic element, k> which gives it greater tolerances at the time of manufacture and use. 5.
  • Said elastic element is in continuous rest and without deformation before and after the shot: it is only at that moment of the shot, when it undergoes compression for tenths of a second. Therefore, the useful life of this element is almost unlimited.
  • This element can be a linear or conical metal spring, or an elastomer, or an air compression element or an electromagnet.
  • This element C is optional, being unnecessary in the cases in which the energy released in the recoil is small and it can be absorbed simply by the friction inherent in the system. If necessary, this element C will be responsible for absorbing kinetic energy from the recoil of the weapon in either of the two directions. Without more than changing its properties (such as the elastic constant, for example) we can adapt the proposed system for weapons of different power in the muzzle and therefore, with more or less strong recoil and of greater or less distance.
  • Element C is Installed inside and at one end of element A.
  • E - End of travel stopper its mission is to walk and / or support element C and other ergonomic elements such as a nock, for example.
  • element C it is optional, being unnecessary in cases where the energy released in the recoil is small and this can be absorbed simply by the friction inherent in the system.
  • element D can act as a plug for the air compression chamber that is formed when inside element A, element D makes its linear travel towards the shooter's shoulder, being able to compress air or not, by making the element watertight.

  • Each of these elements H are fixed in their position fixed to the chassis element A, by a simple screw, element I screwed to the chassis, element A.
  • the slots have two areas separated by a strangulation caused by two small projections: An area where the elastic ring is immobilized, element H and another area, where the ring has a useful travel free of impediments, always in the direction of the longitudinal axis of the barrel of element A.

  • the elastic rings, elements H which are integral with the cylinder, element A, thanks to the fixing screws, elements I are subjected to a drag force and the result is a deformation of the elastic rings H, which causes the sliding rings, elements B, to be compressed and can move, overcoming the throttling present in the guides, elements F.

Thanks also to these opposing grooves and the elastic rings, the guidance of the weapon inside the cylinder is optimal, not allowing it to rotate inside it, also giving the elastic nature of the H element, a greater tolerance margin than any other retaining element. metal.
