Adjustable support structure for sitting force-free cannon

Abstract

The utility model discloses an adjustable support structure for a sitting force-free gun, and relates to the technical field of gun supports. The support structure is matched with the non-sitting force gun and is connected with a picatinny guide rail of a weapon through an upper adjustable pickup truck, and the height of the support structure can be telescopically adjusted according to different terrains and actual shooting differences of different operators. When the shooting position is adjusted, in order to meet the requirement of quick response, the support meets the requirement that the shooting direction is changed while the bottom end supporting component is not moved. By means of the support structure, the supporting problem of the non-sitting-force cannon during prone shooting is solved, and the problems that when firearms are used for shooting, the height of a support is single, and the direction cannot be adjusted are solved.

Description
