The carbine assembly may include an upper receiver, a lower receiver, a feed ramp, a bolt stop, a magazine, a control mechanism comprising a control lever, a control base, a control pivot pin, and a control spring, an ejector, a gap filler member. The assembly provides last round bolt hold open, trigger finger actuated bolt release, short stroke cycle, barrel ramp, ambidextrous magazine release, and uses Glock magazines.
1. A carbine assembly comprising:
an upper receiver;
a lower receiver with a magazine fillable with ammunition, wherein the magazine is removably coupled to the lower receiver; and
a bolt stop/feed assembly coupled within the upper receiver and the lower receiver, the bolt stop/feed assembly comprising a bolt stop rotatably coupled to a feed ramp, wherein the bolt stop rotates with respect to the feed ramp and the bolt stop/feed assembly is configured to feed ammunition into a barrel of the carbine assembly and stop operation of the bolt carrier when a last round of ammunition is fired from the carbine assembly upper receiver.
2. The assembly of claim 1 , further comprising an ejector coupled to the upper receiver.
3. The assembly of claim 1 , wherein the feed ramp comprises a cartridge feed ramp surface that extends from a first surface to a second surface of the feed ramp.
4. The assembly of claim 3 , wherein the feed ramp further comprises protrusion members extending from each side of the feed ramp surface, each protrusion member having a tapered surface, wherein the feed ramp surface and protrusion members with tapered surfaces operate to direct a round of ammunition into the barrel.
5. A carbine assembly comprising:
a lower receiver with a magazine fillable with ammunition, the magazine removably coupled to the lower receiver, wherein the lower receiver comprises:
a right-side gap and a left-side gap for receiving a control arm through the right-side gap for a right-hand shooter or receiving the control arm through the left-side gap for a left-hand shooter; and
a gap filling device removably coupled to the left-side gap for a right-hand shooter and coupled to the right-side gap for a left-hand shooter;
an upper receiver configured for a left-hand shooter or a right-hand shooter;
a bolt stop/feed assembly coupled within the upper receiver and the lower receiver and operatively coupled to the control arm, the bolt stop/feed assembly comprising a bolt stop rotatably coupled to a feed ramp, wherein the bolt stop rotates with respect to the feed ramp and the bolt stop/feed assembly is configured to feed ammunition into a barrel of the carbine assembly and stop operation of the bolt carrier when a last round of ammunition is fired from the carbine assembly upper receiver.
6. The assembly of claim 5 , further comprising an ejector coupled to the upper receiver.
7. The assembly of claim 5 , wherein the feed ramp comprises a cartridge feed ramp surface that extends from a first surface to a second surface of the feed ramp.
8. The assembly of claim 7 , wherein the feed ramp further comprises protrusion members extending from each side of the feed ramp surface, each protrusion member having a tapered surface, wherein the feed ramp surface and protrusion members with tapered surfaces operate to direct a round of ammunition into the barrel.
