Abstract

Described herein is an integrated feed ramp for a shotgun, methods for making same, and methods of retrofitting existing firearms, wherein the integrated feed ramp feeds shells directly into the loading port of the magazine tube of the shotgun.

Claims (36)

1 . An integrated feed ramp for a shotgun comprising:

at least one ramp wherein the at least one ramp is formed as part of at least one trigger guard;

at least one engagement surface defined on the at least one ramp configured to engage at least one shotgun shell;

at least one proximal end of the at least one feed ramp and at least one distal end of the at least one feed ramp;

wherein the at least one distal end of the at least one feed ramp is configured to deliver the at least one shotgun shell into at least one loading port of the shotgun; and

wherein the at least one ramp is configured to be removable with respect to the at least one trigger guard.

2 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one ramp is integral with the at least one trigger guard.

3 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one ramp comprises at least one polymer, steel or aluminum.

4 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one feed ramp Is concave.

5 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one ramp varies in width along a length of the integrated feed ramp.

6 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one integrated feed ramp varies in depth along a length of the integrated feed ramp.

7 . The integrated feed ramp for a shotgun of claim 1 , wherein the at least one feed ramp varies in depth and in width along a length of the integrated feed ramp.

8 . The integrated feed ramp for a shotgun of claim 1 , wherein the integrated feed ramp is formed in at least two sections to comprise a length of the integrated feed ramp.

9 . A method for forming an integrated feed ramp for a shotgun comprising:

forming at least one ramp wherein the at least one ramp is formed as part of at least one trigger guard;

defining at least one engagement surface on the at least one ramp configured to engage at least one shotgun shell;

forming at least one proximal end of the at least one feed ramp;

forming at least one distal end of the at least one feed ramp;

configuring the at least one distal end of the at least one feed ramp to deliver the at least one shotgun shell into at least one loading port of the shotgun; and

comprising configuring the at least one ramp as removable with respect to the at least one trigger guard.

10 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising forming the at least one ramp as integral with the at least one trigger guard.

11 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising forming the at least one ramp from at least one polymer, steel or aluminum.

12 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising configuring the at least one feed ramp as concave.

13 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising configuring the at least one ramp to vary in width along a length of the integrated feed ramp.

14 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising configuring the at least one integrated feed ramp to vary in depth along a length of the integrated feed ramp.

15 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising configuring the at least one feed ramp to vary in depth and in width along a length of the integrated feed ramp.

16 . The method for forming an integrated feed ramp for a shotgun of claim 9 , comprising configuring the integrated feed ramp in at least two sections to comprise a length of the integrated feed ramp.

17 . A method for retrofitting an existing shotgun platform to incorporate an integrated shotgun ramp comprising:

removing an existing trigger guard from a shotgun body;

smoothing any rough surface areas employed to secure the existing trigger guard to the shotgun body; and

securing an integrated trigger guard frame into a location where the existing trigger guard had occupied.

18 . The method for retrofitting an existing shotgun platform to incorporate an integrated shotgun ramp of claim 17 , wherein the integrated trigger guard frame includes:

at least one ramp wherein the at least one ramp is formed as part of at least one integrated trigger guard frame;

at least one engagement surface defined on the at least one ramp configured to engage at least one shotgun shell;

at least one proximal end of the at least one feed ramp and at least one distal end of the at least one feed ramp; and

wherein the at least one distal end of the at least one feed ramp is configured to deliver the at least one shotgun shell into at least one loading port of the shotgun.
