Firearms chongmom coupling device that complements the coupling of the upper and the lower chongmom chongmom

摘要

In firearms which chongmom is open to the upper and the lower chongmom chongmom, the upper and lower engaging portion has chongmom will receive a significant amount of curl and the gap. Chongmom coupling device of the subject innovation are proposed to compensate for rigidly coupling the upper and lower chongmom to eliminate the distortion or the gap of the upper and lower chongmom. From the present design it has the following advantages.; First, according to the chongmom gun that opens to the upper and the lower chongmom chongmom, to prevent injuries such as prevent the separation of the upper and lower chongmom not the intention with the firing of the projectile shooter to blindness. Second, in the gun it is chongmom is opened to the upper and the lower chongmom chongmom, to reduce the error of the foam when the bullet trajectory to raise the accuracy of the mark. Third, in the gun it is chongmom is opened to the upper and the lower chongmom chongmom, reducing the impact and rebound of the projectile during firing. Fourth, in the gun is chongmom is opened to the upper and the lower chongmom chongmom, it solves the problem that releasing the bolt retracted fixed unintentionally. Firearm according to the fifth, chongmom this which opens into the upper and the lower chongmom chongmom be eliminated deolgeureok noises generated in the upper and lower chongmom heundeulrimyeonseo each other.
