Benefits of technology

[0016] Barrel tubes join the muzzle block to the extended chopper block to produce a barrel assembly. These barrel tubes can be made 30 to 40% shorter than other barrel construction means and thereby can be manufactured easier and more effectively to tighter quality standards for straightness, concentricity, and bore finish.
[0017] The barrel tubes have the ability to be standard bored or over-bored to provide less felt recoil when firing the shotgun. The barrel tubes are threaded on the muzzle block end for the shock proof joint benefits stated earlier. The barrel tubes have a slip fit joint on the extended chopper block end as stated earlier.
[0018] The barrel tubes do not have to be shaved to provide a low overall height of the barrel assembly as they join the extended chopper block beyond the extended or long forcing cone area. Basically all of the heavy thick barrel section is part of the extended chopper ...

Problems solved by technology

This process is tedious and requires considerable handwork to remove chemical fluxes and excess solder or braze.
Excessive heat from the process can also distort the barrels and impact the quality of t...

Embodiment Construction

[0051] A complete barrel assembly is illustrated in the FIG. 1 perspective view of a multi-barreled shotgun barrel assembly.

[0052] The barrel assembly is simplified into four main components in the FIG. 2 exploded view of the barrel assembly. These components are the Extended Chopper Block 1, the Upper Barrel Tube 2A, the Lower Barrel Tube 2B, the Muzzle Block 3, and the Top Rib Sighting Plane 4.

[0053]FIG. 3, exploded cross-sectional view of the barrel assembly, illustrates the internal features and characteristics of this type of barrel construction. The Extended Chopper Block 1 has a length sufficient to for a Shot Shell Chamber Area 12 providing for shot shells of all lengths along with an Extended or Long Forcing Cone Area 13 which transitions the shot column when the shotgun is fired from the chamber internal diameter to the Barrel Bore in the Extended Chopper Block 14A. This Extended Chopper Block construction contains all forces produced when firing the shot shells in the g...

Abstract

A multi-barreled shotgun barrel assembly construction, which breaks down barrel components into a Muzzle Block, Extended Chopper Block, and Barrel Tubes that join the two blocks enabling precise alignment to direct shot to a desired point of impact.

Description

BACKGROUND [0001] 1. Field of Invention [0002] This invention relates to firearms and more particularly to improvements in the construction and functionality of shotgun barrels. [0003] 2. Description of the Related Art [0004] Traditionally shotgun barrels construction has either been chopper lump or mono-block construction in multi-barreled shotguns. [0005] Chopper lump construction entails manufacturing barrel tubes in various ways and allowing extra material on the breech end. This extra material provided a way to join the barrels by forming this material into a dovetailed joint. Barrels are also shaved to create flat areas of contact to allow the barrels to fit closer together so lower overall heights and widths are achieved. This procedure reduces weight while lowering the overall height to provide a more naturally pointing firearm. [0006] The muzzle end of the barrel set, ribs for the top sighting plane and side covers are joined by soldering, brazing, or welding. All of these ...
