Firearm cartridge ejector
A firearm cartridge ejector system is disclosed that may include a bolt or a bolt carrier group, and an ejector that may be configured to eject an ammunition cartridge from the firearm bolt or bolt carrier group. The ejector may further include a stem configured to engage an ejector spring, and an ejector face that may be reniform-shaped and attached to the stem and configured to engage and eject the ammunition cartridge.
1. A firearm cartridge ejector system comprising:
a bolt; and
an ejector configured to eject a cartridge from a firearm bolt, wherein the ejector is movably positioned in the bolt,
wherein the ejector further comprises a stem configured to engage the bolt, and an ejector face attached to the stem and configured to engage the cartridge, wherein the ejector face is reniform-shaped and comprising a curvilinear protrusion positioned at a midpoint between a first end of the ejector face and a second end of the ejector face.
2. The system of claim 1 , wherein the ejector is a polymer.
3. The system of claim 1 , wherein the ejector is a metal or an alloy.
4. The system of claim 1 , wherein the ejector face is planar.
5. The system of claim 4 , wherein the ejector face is curved.
6. The system of claim 5 , wherein the ejector face is concave.
7. The system of claim 1 , wherein the stem is positioned perpendicular to the ejector face, and wherein the stem extends proximally from a rear side of the ejector face.
8. The system of claim 7 , wherein the stem includes a notch configured to engage an ejector roll pin.
9. The system of claim 1 , wherein an interior portion of the ejector face is concave.
10. The system of claim 9 , wherein the interior portion of the ejector face further includes a protrusion positioned between a first end of the ejector face and a second end of the ejector face.
11. The system of claim 10 , wherein the protrusion is convex and curvilinear.
12. The system of claim 1 , wherein the ejector face includes a plurality of ridges and grooves.
13. A firearm comprising the firearm cartridge ejector system of claim 1 .
14. A firearm cartridge ejector comprising:
a stem; and
an ejector face attached to the stem, wherein the ejector face is reniform-shaped and comprising a curvilinear protrusion positioned at a midpoint between a first end of the ejector face and a second end of the ejector face, wherein the firearm cartridge ejector is configured to engage a bolt or a bolt carrier group.
15. The firearm cartridge ejector of claim 14 , wherein the ejector is a polymer, a metal, or an alloy.
16. The firearm cartridge ejector of claim 15 , wherein the ejector face is nonplanar.
17. The firearm cartridge ejector of claim 16 , wherein an interior portion of the ejector face is concave.
18. The firearm cartridge ejector of claim 17 , wherein the interior portion of the ejector face further includes a protrusion positioned between a first end of the ejector face and a second end of the ejector face.
19. The firearm cartridge ejector of claim 18 , wherein the protrusion is convex and curvilinear.
20. A firearm including a cartridge extraction system comprising:
a bolt carrier group configured to insert, extract, and eject a firearm cartridge from a weapon, wherein the bolt carrier group further comprises:
a bolt; and
an ejector, wherein the ejector further comprises:
an ejector stem configured to slidably engage the bolt; and
an ejector face attached to the ejector stem and configured to eject the firearm cartridge from the bolt, wherein the ejector face is reniform-shaped and comprising a curvilinear protrusion positioned at a midpoint between a first end of the ejector face and a second end of the ejector face.
