Abstract

A mounting apparatus for mounting an accessory to a weapon is disclosed. In some embodiments, the mounting apparatus includes a base plate having a side member parallel to a longitudinal axis of the base plate. The base plate is configured to be coupled to an under barrel of a firearm. The mounting apparatus further includes one or more opposing side elements. Each side element is detachably coupled to the respective side member of the base plate such that the side element is positioned adjacent to a movable slide mechanism of the firearm while the base plate is coupled to the under barrel. In some embodiments, the mounting apparatus includes an adapter bridge and/or a barrel weight, which, in combination with the side elements, straddles, and avoids interfering with, the movable slide mechanism while the assembly is mounted to the firearm.

Claims

1. A mounting apparatus comprising:

a base plate having a side member parallel to a longitudinal axis of the base plate, the base plate being configured to be coupled to an under barrel of a firearm;

a side element detachably coupled to the side member of the base plate such that the side element is positioned adjacent to a movable slide mechanism of the firearm while the base plate is coupled to the under barrel; and

a first tongue disposed on the side member of the base plate and a second tongue disposed on the side element, wherein the first tongue and the second tongue are each configured to engage a complementary groove formed on one side of the under barrel.

2. The apparatus of claim 1, wherein the base plate has an opposing side member parallel to the longitudinal axis of the base plate, and wherein the apparatus further comprises an opposing side element detachably coupled to the opposing side member of the base plate such that both side elements are positioned adjacent to the movable slide mechanism of the firearm while the base plate is coupled to the under barrel.

3. The apparatus of claim 2, further comprising an adapter bridge coupled to at least one of the side elements such that the adapter bridge is positioned above and avoids interfering with the movable slide mechanism while the adapter bridge is mounted to the firearm.

4. The apparatus of claim 3, wherein the adapter bridge includes one of a Picatinny rail and an optic-specific mount for mounting an accessory thereto.

5. The apparatus of claim 2, further comprising a barrel weight coupled to at least one of the side elements such that the barrel weight straddles a muzzle of the firearm while the base plate is coupled to the under barrel.

6. The apparatus of claim 1, further comprising a screw, wherein the side member and the side element each have bores configured to be axially aligned with each other and to receive the screw for securing the side member and the side element together.

7. The apparatus of claim 1, wherein the first tongue is configured to be axially aligned with the second tongue while the side element is coupled to the side member of the base plate.

8. The apparatus of claim 1, further comprising a fastener configured to secure the base plate to the under barrel.

9. The apparatus of claim 8, wherein the fastener is threaded into an opening formed through the base plate.

10. A kit comprising:

a base plate having a side member parallel to a longitudinal axis of the base plate, the base plate being configured to be coupled to an under barrel of a firearm; and

a side element configured to be detachably coupled to the side member of the base plate such that the side element is positioned adjacent to a movable slide mechanism of the firearm while the base plate is coupled to the under barrel;

wherein a first tongue is disposed on the side member of the base plate and a second tongue is disposed on the side element, and wherein the first tongue and the second tongue are each configured to engage a complementary groove formed on one side of the under barrel.

11. The kit of claim 10, wherein the base plate has an opposing side member parallel to the longitudinal axis of the base plate, and wherein the apparatus further comprises an opposing side element configured to be detachably coupled to the opposing side member of the base plate such that both side elements are positioned adjacent to the movable slide mechanism of the firearm while the base plate is coupled to the under barrel.

12. The kit of claim 11, further comprising an adapter bridge configured to be coupled to at least one of the side elements such that the adapter bridge straddles and avoids interfering with the movable slide mechanism while the adapter bridge is mounted to the firearm.

13. The kit of claim 12, wherein the adapter bridge includes one of a Picatinny rail and an optic-specific mount for mounting an accessory thereto.

14. The kit of claim 11, further comprising a barrel weight configured to be coupled to at least one of the side elements such that the barrel weight straddles a muzzle of the firearm while the base plate is coupled to the under barrel.

15. The kit of claim 10, further comprising a screw, wherein the side member and the side element each have bores configured to be axially aligned with each other and to receive the screw for securing the side member and the side element together.

16. The kit of claim 10, wherein the first tongue is configured to be axially aligned with the second tongue while the side element is coupled to the side member of the base plate.

17. The kit of claim 10, further comprising a fastener configured to secure the base plate to the under barrel.

18. The kit of claim 17, wherein the fastener is threaded into an opening formed through the base plate.

19. A mounting apparatus comprising:

a base plate having a side member parallel to a longitudinal axis of the base plate, the base plate being configured to be coupled to an under barrel of a firearm;

a pair of opposing side elements each extending upwardly from respective side members of the base plate such that the side elements are positioned adjacent to a movable slide mechanism of the firearm while the base plate is coupled to the under barrel; and

a first tongue disposed on the side member of the base plate and a second tongue disposed on at least one of the opposing side elements, wherein the first tongue and the second tongue are each configured to engage a complementary groove formed on one side of the under barrel.

20. The apparatus of claim 19, further comprising an adapter bridge coupled to at least one of the side elements such that an assembly comprising the base plate, at least one of the side elements and the adapter bridge straddles, and avoids interfering with, the movable slide mechanism while the assembly is mounted to the firearm.
