B. Scoped Rifle Model 1955

38 Scoped rifle Model 1955 is a weapon for precision shooters. It is a firearm that resembles the Mq.

Mod 31. In the hands of a good marksman, it is capable of destruction, using few cartridges, up to

distances of 500 to 600 meters, of targets isolated and not easily visible to the naked eye or in dim

lighting conditions. The scope not only facilitates sight, but also permits observation of the target

area. Thanks to good optics, an enlarged visual field and the stability of the weapon (bipod,

muzzle brake, weight of the weapon) one may observe the arrival of the shot on target.
