Abstract

A feed assembly of an assault rifle for feeding rounds of ammunition to a firing chamber includes an ammunition feed that is cooperable with the firing chamber. The ammunition feed simultaneously receives a magazine biased to deliver rounds of ammunition to the firing chamber and a belt feed system for feeding belted rounds of ammunition to the firing chamber. A selector is interconnected to a pawl and a magazine cover. The selector simultaneously actuates the pawl and the magazine cover alternately opening and closing the pawl and the magazine cover for selectively feeding rounds of ammunition from the belt feed system or the magazine into the firing chamber.

Claims

1. A feed assembly and assault rifle combination for feeding rounds of ammunition to a firing chamber of said assault rifle, comprising:

an ammunition feed cooperable with a firing chamber, said ammunition feed simultaneously receiving a magazine biased to deliver rounds of ammunition to said firing chamber and a belt feed system for feeding belted rounds of ammunition to said firing chamber;

a selector interconnected to a feed pawl and a magazine cover, said selector simultaneously actuating said feed pawl and said magazine cover alternately opening and closing said feed pawl and said magazine cover for selectively feeding rounds of ammunition from said belt feed system or said magazine into said firing chamber; and

said selector lowering said magazine when actuated to feed rounds of ammunition from said belt feed system.

2. The assembly set forth in claim 1, wherein said feed pawl is connected to said selector by a link, said link including an opening element and a closing element for controlling access to said firing chamber to said belt feed system.

3. The assembly set forth in claim 1, wherein said feed pawl defines a cradle for receiving a round of ammunition from said belt feed system when said feed pawl is dispose in a closed position.

4. The assembly set forth in claim 1, wherein said assault rifle includes a barrel and said magazine cover is movable in a direction along said barrel for controlling access to said firing chamber to said magazine.

6. The assembly set forth in claim 1, further including a camming surface translating motion to said feed pawl and said magazine cover when said selector is actuated for actuating said feed pawl between magazine and belt feed position.

7. The assembly set forth in claim 1, wherein said belt feed system includes an ammunition box for retaining said belt feed system for feeding belted rounds of ammunition toward said feed pawl and into said firing chamber.

8. The assembly set forth in claim 1, wherein said magazine is biased toward said firing chamber and the rounds of ammunition disposed in said magazine are biased into the firing chamber when said feed pawl is closed preventing the belted rounds of ammunition from said belt feed system from entering the firing chamber and said magazine cover is disposed in an open position.

9. The assembly set forth in claim 1, wherein said assault rifle is switchable between open bolt firing and close bolt firing.
