Abstract
In a bolt actuated firearm having a cartridge receiver station communicat linearly with a firing chamber, magnetic means in the receiver station which cooperate with the cartridge magazine or belt to first positively move each cartridge from the magazine or belt into the receiver station and then to releasably hold the cartridge in the station for in line movement into the firing chamber under the influence of the bolt, the magnetic means also guiding axial linear movement of the bolt to its firing chamber position and sequentially thereafter releasably holding the bolt thereby to prevent bounce of the bolt and cartridge until firing of the cartridge.
Claims11
In a firearm assembly having a receiver housing, a reciprocable bolt, a firing chamber in said receiver housing, and an ammunition cartridge feed inlet communicating with said receiver housing for positioning of each cartridge in a guide station in the receiver housing for subsequent linear movement of the cartridge by the bolt into the firing chamber, the improvement comprising:
- magnetic means carried by said receiver for magnetically guiding movement of each cartridge through said inlet to said guide station and for holding each of said cartridges in said station for subsequent movement thereof by the bolt into the firing chamber.
In the method of positioning cartridges in a receiver housing of a firearm actuated by a bolt and having a firing chamber, said positioning being for movement by said bolt into said firing chamber, the steps comprising:
- attracting each cartridge into the receiver housing magnetically for introduction into the firing chamber, and
- sequentially actuating said bolt to move the cartridge into the firing chamber.
