A bolt carrier having a first gas port, wherein the first gas port provides fluid communication between an interior and an exterior of the bolt carrier; a second gas port, wherein the second gas port provides fluid communication between an interior and an exterior of the bolt carrier; and a third gas port, wherein the third gas port provides fluid communication between an interior and an exterior of the bolt carrier.
1. A bolt carrier, comprising:
a first gas port, wherein said first gas port provides fluid communication between an interior and an exterior of said bolt carrier, wherein said first gas port extends from an initial portion to a subsequent portion, wherein said initial portion has a longitudinal axis that is offset 30° to 60° from a longitudinal axis of said bolt carrier, and wherein said subsequent portion has a longitudinal axis that is offset 10° to 15° from said longitudinal axis of said bolt carrier;
a second gas port, wherein said second gas port provides fluid communication between an interior and an exterior of said bolt carrier, and wherein said second gas port has a longitudinal axis that is offset 70° to 75° from said longitudinal axis of said bolt carrier; and
a third gas port, wherein said third gas port provides fluid communication between an interior and an exterior of said bolt carrier, and wherein said third gas port has a longitudinal axis that is offset 30° to 40° from said longitudinal axis of said bolt carrier.
2. The bolt carrier of claim 1 , wherein said first gas port provides fluid communication between a bolt receiving aperture and/or a firing pin receiving aperture and an exterior of said bolt carrier.
3. The bolt carrier of claim 1 , wherein said initial portion has a longitudinal axis that is offset 40° to 50° from said longitudinal axis of said bolt carrier.
4. The bolt carrier of claim 1 , wherein said initial portion has a longitudinal axis that is offset 45° from said longitudinal axis of said bolt carrier.
5. The bolt carrier of claim 1 , wherein said subsequent portion has a longitudinal axis that is offset 9° to 11° from said longitudinal axis of said bolt carrier.
6. The bolt carrier of claim 1 , further comprising
a boss formed proximate a rear portion of said bolt carrier.
7. The bolt carrier of claim 6 , further comprising
one or more relief cuts in said boss.
8. The bolt carrier of claim 1 , further comprising
one or more relief cuts formed proximate a rear portion of said bolt carrier.
9. The bolt carrier of claim 1 , further comprising
a gas trough formed along at least a portion of said exterior of said bolt carrier.
10. The bolt carrier of claim 9 , wherein said gas trough is formed substantially parallel to said first gas port.
11. A bolt carrier, comprising:
a first gas port, wherein said first gas port provides fluid communication between an interior and an exterior of said bolt carrier, wherein said first gas port extends from an initial portion to a subsequent portion, wherein said initial portion has a longitudinal axis that is offset 30° to 60° from a longitudinal axis of said bolt carrier, and wherein said subsequent portion has a longitudinal axis that is offset 10° to 15° from said longitudinal axis of said bolt carrier; and
a second gas port, wherein said second gas port provides fluid communication between an interior and an exterior of said bolt carrier, and wherein said second gas port has a longitudinal axis that is offset 70° to 75° from said longitudinal axis of said bolt carrier.
12. The bolt carrier of claim 11 , wherein said first gas port provides fluid communication between a bolt receiving aperture and a firing pin receiving aperture and an exterior of said bolt carrier.
13. The bolt carrier of claim 11 , wherein said second gas port provides fluid communication between a bolt receiving aperture and/or a firing pin receiving aperture and an exterior of said bolt carrier.
14. The bolt carrier of claim 11 , wherein said initial portion of said first gas port has a longitudinal axis that is offset 40° to 50° from said longitudinal axis of said bolt carrier.
15. The bolt carrier of claim 11 , further comprising
a boss formed proximate a rear portion of said bolt carrier.
16. The bolt carrier of claim 15 , further comprising
one or more relief cuts in said boss.
17. The bolt carrier of claim 11 , further comprising
a gas trough formed along at least a portion of said exterior of said bolt carrier.
18. A bolt carrier, comprising:
a gas port, wherein said first gas port provides fluid communication between an interior and an exterior of said bolt carrier, wherein said gas port extends from an initial portion to a subsequent portion, wherein said initial portion has a longitudinal axis that is offset 30° to 60° from a longitudinal axis of said bolt carrier, and wherein said subsequent portion has a longitudinal axis that is offset 10° to 15° from said longitudinal axis of said bolt carrier.
19. The bolt carrier of claim 18 , wherein said first gas port provides fluid communication between a firing pin receiving aperture and an exterior of said bolt carrier.
20. The bolt carrier of claim 18 , wherein said first gas port has a longitudinal axis that is offset 45° from said longitudinal axis of said bolt carrier.
