Abstract

A mount for a firearm allows a user to selectively mount a handgrip to a barrel end of the firearm. Preferred embodiments mount to a Picatinny rail of the firearm. The mount includes a rotatable lug body that is carried within an internal cavity of the body of the mount. Differing lugs corresponding to differing handgrip types are disposed on the lug body. The user simply rotates the lug body within the mount to select a desired lug corresponding to a desired handgrip. The handgrip may then be secured to the selected lug. When the user wants to secure a different handgrip, the first handgrip may be removed, the lug body rotated, and another handgrip is secured to the another lug.

Claims (35)

1. A handgrip mount for a firearm, comprising:

an elongate body having a top end, a bottom end, and an internal cavity defined therein;

a keyed slot disposed at the top end of the elongate body is dimensioned to removably attach to a Picatinny rail of the firearm; and

a lug body rotatably carried within the internal cavity, the lug body comprising a plurality of lugs, the plurality of lugs radially project from a center of rotation of the lug body, each of the plurality of lugs dimensioned to mount to a base of a selected one of a plurality of handgrips.

2. The handgrip mount of claim 1 , further comprising:

a handgrip attachment aperture defined in an end face of each of the plurality of lugs, the handgrip attachment aperture adapted to receive a fastener to attach the selected one of the plurality of handgrips to a corresponding lug.

3. The handgrip mount of claim 1 , the keyed slot further comprising:

a first lateral edge defined by a protrusion of the elongate body; and

a second lateral edge defined by a detachable side plate, the detachable side plate secured to the elongate body via one or more fasteners.

4. The handgrip mount of claim 1 , further comprising:

a pivot hole extends transversely through the lug body;

an aperture extends through a lateral sidewall of the elongate body; and

a pivot pin received through each of the pivot hole and the aperture to rotatably carry the lug body within the internal cavity.

5. The handgrip mount of claim 1 , wherein the plurality of lugs further comprise:

a first lug dimensioned to receive a first handgrip; and

a second lug dimensioned to receive a second handgrip.

6. The handgrip mount of claim 5 , wherein the first handgrip is an M-16/AR-15 handgrip and the second handgrip is an AK-47 handgrip.

7. A handgrip mount for a firearm, comprising:

an elongate body having an internal cavity defined along a longitudinal length of the elongate body, and an opening to the internal cavity at a bottom face of the elongate body;

a clamp coupling defined at a top end of the elongate body, the clamp coupling configured for attachment to a barrel end of the firearm; and

a lug body rotatably carried within the internal cavity, the lug body comprising a plurality of lugs, wherein a rotation of the lug body exposes a selected one of the plurality of lugs to the opening of the internal cavity, each the plurality of lugs dimensioned to mount with a differing base of one of a plurality of handgrips.

8. The handgrip mount of claim 7 , wherein the clamp coupling is adapted to couple to a Picatinny rail disposed on the barrel end of the firearm.

9. The handgrip mount of claim 7 , the claim coupling further comprising:

a keyed slot defined at the top end of the elongate body, the keyed slot having a first lateral edge dimensioned to receive a first side of a Picatinny rail and a plate, operable to clamp a second side of the Picatinny rail.

10. The handgrip mount of claim 1 , further comprising:

a pivot pin received through each of the lug body and the elongate body to rotatably carry the lug body within the internal cavity.

11. A method of adapting a handgrip to a firearm, comprising:

attaching a handgrip mount to a barrel end of the firearm;

selecting one of a plurality of lugs from a lug body rotatably carried within an interior cavity of the handgrip mount, wherein a selected one of the plurality of lugs is exposed through a bottom opening to the interior cavity, and

attaching a first handgrip to the selected one of the plurality of lugs, the first handgrip having a first base corresponding to the selected one of the plurality of lugs.

12. The method of claim 11 , further comprising:

removing the first handgrip from the selected one of the plurality of lugs.

13. The method of claim 12 , further comprising:

rotating the lug body to select another of the plurality of lugs; and

attaching a second handgrip having a second base corresponding to the selected another of the plurality of lugs.
