Abstract

An integrated grip and rail system is provided. Included is a firearm and the firearm grip. The grip is configured to be disposed in front of the magazine well and provide a stable grip point which does not allow a user's thumb or other appendage to be disposed between the grip and magazine well. The grip is configured so as to not interfere with the pivoting relationship between the weapon upper and weapon lower during partial or complete disassembly of the weapon. The rear region may also have a portion extending rearward along at least part of each side of the magazine well to form feed ramps as a part of the magazine well extension. Included is a magazine well extension mechanically coupled to a forearm rail system for mounting to the firearm.

Claims (25)

1. A firearm grip for a firearm having a lower receiver, an upper receiver, a forend extending from the upper receiver, and a forward magazine well, the upper and lower receivers attached to each other in a closed position by a front pin and a rear pin, and pivotably moveable with respect to each other at the front pin when the rear pin is withdrawn;

the grip comprising:

a grip portion configured to extend downward from the firearm forend;

an attachment portion adapted to attach the grip to the firearm in two positions, a first position such that the grip portion is immediately forward of the magazine well when the upper and lower receivers are in the closed position, and a second position such that the grip does not interfere with the pivoting of the upper and lower receivers when the rear pin is withdrawn; and

a magazine well extension portion extending rearward from the grip portion to at least partially surround the magazine well of the firearm when the grip is in its first position.

2. The firearm grip of claim 1 wherein the magazine well extension portion has at least two angled feed ramps.

3. The firearm grip of claim 1 , the grip portion defining a chamber to house at least one electronic component.

4. A firearm grip for a firearm having an upper receiver component having a forend, and a lower receiver component having a forward magazine well, the upper receiver component and lower receiver component attached to each other in a closed position by a front pin and a rear pin, and pivotably moveable with respect to each other at the front pin when the rear pin is withdrawn;

the grip comprising: a grip portion configured to extend downward from the firearm forend; an attachment portion adapted to attach the grip to the firearm in two positions, a first position such that the grip portion is immediately forward of the magazine well, and a second position such that the grip does not interfere with the pivoting of the upper receiver component and lower receiver component when the rear pin is withdrawn; and a magazine well extension portion extending rearward from the grip portion to at least partially surround the magazine well of the firearm when the grip is in its first position.

5. The firearm grip of claim 4 , the grip portion defining a chamber to house at least one electronic component.

6. A firearm grip comprising: a forend; a grip portion connected to the forend and moveable between a first attached position and a second attached position with respect to the forend to which it is connected; the grip portion including angled feed ramps to aid in magazine insertion, and a front hollow wall accessible for the storage of auxiliary electronic devices.

7. The grip of claim 6 wherein the forearm is a rail system for a weapon having a weapon upper, a weapon lower, and a forward magazine well, the weapon upper and weapon lower engageable in a pivoting relationship.

8. The grip of claim 6 wherein the angled feed ramps include a front angled feed ramp, a rear angled feed ramp, and two side angled feed ramps, and the dimensions of at least two of the angled feed ramps are different.

9. A grip for a firearm having a firearm upper, a firearm lower, and a forward magazine well, the firearm upper and firearm lower engageable in a pivoting relationship, the grip comprising: a magazine portion adapted to extend generally downward along at least a part of the front of the magazine well so as to prevent the insertion of any part of the hand of the user between the grip and the front of the magazine well; the magazine portion moveable between a firing position and an open position, the open position allowing for movement between the weapon upper and weapon lower during partial or complete disassembly of the weapon.

10. The grip of claim 9 further comprising a forearm attached to the magazine portion.

11. The grip of claim 9 further comprising a forearm attached to the magazine portion, the forearm comprising a rail system adapted to allow the mounting of auxiliary equipment to the grip.

12. The grip of claim 9 wherein the magazine portion further comprises a rear grip portion which extends around the back of the magazine well to form at least one angled feed ramp surface to aide in magazine insertion into the magazine well.

13. The grip of claim 9 wherein the magazine portion further comprises a rear grip portion which extends around the back of the magazine well to form a front angled feed ramp, a rear angled feed ramp, and two side angled feed ramps.

14. The grip of claim 9 wherein the magazine portion further comprises a rear grip portion which extends around the back of the magazine well to form a front angled feed ramp, a rear angled feed ramp, and two side angled feed ramps, and the dimensions of at least two of the angled feed ramps are different.

15. A grip for a firearm having a forward magazine well configuration, the grip comprising: a forearm; a rear portion configured to extend generally downward along at least a part of the front of the magazine well when the grip is attached to the firearm, the rear portion forming a storage cavity in front of the magazine well and angled feed ramps to aid in magazine insertion into the magazine well when the grip is attached to the firearm.

16. The grip of claim 15 , wherein the feed ramps do not all have the same dimensions.

17. A firearm having an upper, a lower, a forward magazine well, and a grip, comprising: a portion of the grip extending generally downward along at least a part of the front of the magazine well so as to prevent the insertion of any part of the hand of the user between the grip and the front of the magazine well, the grip configured so as to not interfere with the pivoting relationship between the upper and lower during partial or complete disassembly of the firearm.

18. The firearm of claim 17 , wherein the grip is adapted to mechanically couple to the firearm in a first position compatible with a firing position, and to move to a second position compatible with pivoting the upper and lower to a non-firing position.

19. The grip of claim 9 , further comprising a chamber in the grip to house at least one electronic component.

20. The firearm of claim 17 , further comprising a chamber in the grip to house at least one electronic component.
