  • Patent number: 9207029
    Abstract: An ammunition magazine follower comprises a main bottom member defining an upper and lower surface. The upper surface comprises a substantially flat portion and a parallel ridge portion, where the flat and ridge portions are arranged in the longitudinal direction of the main bottom member. One or more guides are arranged on the lower surface for guiding the follower in the magazine. An urging member such as a spring, when installed in a magazine, urges the follower away from the magazine bottom. The guide comprises at least one end wall projecting perpendicularly away from the lower surface of the main bottom member. The end wall comprises a moveable tap, where the upper part of the tap is biased and projects partly above the upper surface of the main bottom member.

  • Patent number: 7878184
    Abstract: A hardball weapon for use in exercises or shooting games and designed as military gun is made with a weapon housing (3) containing two coaxial pistons (21, 26) which are mounted directly in the weapon housing (3) and driven by an electric motor (10) via a gear wheel mechanism (12, 18) and toothed racks (24, 25). The first outer piston (21) functions as a movable bolt for loading the cartridge chamber with cartridges (7) with solid balls (6), and the other piston (26) functions as a pressurised air piston for creating an overpressure for firing the balls (6). The weapon housing (3) can be opened by pivoting, thereby giving access to the parts in the firing mechanism for inspection, repair and adjustment.
