Description

Auxiliary device for calibrating center of firearm

Technical Field

The invention relates to the field of firearm collimation center calibration, in particular to an auxiliary device for calibrating the firearm collimation center.

Background

Most firearms are equipped with aiming mechanisms, typically comprising a sight and a sight, the sight having a notch. Under the condition that the aiming structure of the firearm is correctly calibrated, the gap, the sight and the target object are in a line of three points, and then the bullet shot by the firearm can hit the target; wherein, the point on the same line with the gap and the sight is the center of alignment.

After the firearm is used, the internal parts often need to be maintained and cleaned, which requires disassembly and assembly of the firearm. At present, most firearms are detachable, and after the firearms are detached and then assembled, the aim of aiming can not be guaranteed to be correct, namely the firearms can not be guaranteed to hit a target through the gap and the alignment of the sight; therefore, the firearm is generally required to be aligned with a new alignment center after being disassembled and assembled so as to ensure the accuracy of the aiming structure.

The traditional calibration method usually uses a trial and error method, i.e. a gun opening test, judges the deviation of aiming through the impact point, and then makes corresponding adjustment to the aiming star or sight. In this way, it may need to try many times to complete the calibration, which not only wastes bullets, but also has long calibration time and low efficiency.
