SE448654B - Butt end adjustment arrangement for test hunting gun - Google Patents

Abstract

The training or testing hunting gun has adjustable butt end and a measurement jig in which is fitted the gun barrel, with the one butt side alongside a first registering surface. The butt cover locates along a second such surface. By means of pins and holes in the butt, the position of the butt and reference marks on the registering surfaces can be related to one another. For adjustment of the butt a light cartridge and target box are used, and for successive checking of adjustment and practice of pivot movements, and electro-optic target path and light sources arranged in sequence are employed, together with photo-detectors.

Description

10 448 654 2 rifle and a hit indicator according to the invention. With using a measuring jig can then required measurements transferred from the set piston of the test rifle.

The gunsmith or the piston manufacturer, who has the rifle and measuring jig of completely identical kind, can attach his test rifle 1 his measuring jig and set it according to the aforementioned measurements and then use their rifle as a model in piston manufacturing.

The invention will be described in more detail in the following with reference to the accompanying drawing, which is a view of a hit useful in, among other things, a weapons test equipment indicator in the form of a light hit box according to the invention.

The above-mentioned setting of a test rifle piston is suitably made by means of a light hit box construction shown in the drawing. The light matchbox remains more precisely by a casing l with an open side, through which a shooter can observe a reflective glass disc 2 with inseglat hàrkors. Disc 2, which is partially light-transmitting releasing, is located at a 45 ° angle to both the open the plane of the page as one in an adjacent side of the housing mounted frosted glass top 3 with the crosshair, which is mirrored in the disc 2. Behind the reflective glass disc 2 is further a mat plate 4 arranged in front of one or more light sources s, whose luminosity is lnstallhar by means of a regulator 6.

When shooting at what is reflected in the reflective disc 2 the crosshair with the help of the test rifle or other rifle with light cartridge mounted in it of conventional blow, when the rifle is fired, a beam of light will f emitted to the light box. The point of impact of the light beam relative to the crosshair will be able to be observed on the glass plate 3, while the shooter may be prevented from detecting the meeting point by appropriate setting of the lighting from the light sources S behind the mat plate 4. 7 Thanks to the fact that the crosshairs are reflected from the carpet 3, no error occurs in the hit point indication and this completely independent of the shooter's position relative 448m654 3 the light hit box fl By preventing the slaytten from perceiving the point of impact, it will also be possible to prevent it unconscious change that a shooter makes in his rifle range when he sees the hit position at the shooting. A correct setting = The piston of the test rifle will thus be possible.
