External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for long arms

Abstract

External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for tong arms comprised of external chassis, mobile anchorage by means of internal sliding rings, automatic positioning system by means of a pin and an arm retention system by means of a set of guides and elastic rings integrated in the sliding rings (B) which attach to the body of an arm (D), leaving the barrel free, with free telescopic movement inside an external chassis (A). It also has a positioning pin (G) to block the movement of the arm load and some guide slots (F) for retaining the arm in a fixed position before firing. Elastic rings (H) and screws (I) prevent the rotation of the sliding rings (B) and therefore of the arm (D) inside the chassis (A).
