gewehrlaufführung for carbines 31 of the swiss army.

摘要

the aim of this invention is the precision of the karabiners 31 of the swiss army to improve.in addition, a change in the trefferpunktlage prevents heating of the course.the barrel (1) is provided by the attachment of the ring or piston (4) in the area of laufmündung in a rigid cylindrical tube (3) and supported.which of stützelement (5) and the shaft (2) is fixed. thus, the barrel (1) along the axis of the laufbohrung stretch without the angle change.the vibration behaviour of the course (1) through the guide tube (3) is improved, which increases the precision.
