Abstract

Embodiments of the invention include a firearm system and method of assembly of the firearm system including a receiver complex including a receiver coupled to a forward receiver. A feed port is positioned between the receiver and the forward receiver, and a striker coil assembly is positioned proximate the receiver, and includes a plurality of strikers each extending at least partially through a coil. An interchangeable barrel is coupled to the forward receiver forming a breech. In some embodiments, the firearm system includes a breech that includes a plurality of side-by-side bores of the barrel. Some embodiments include a magazine coupled to the receiver complex adjacent the feedport to simultaneously feed more than one dischargeable projectile into the feedport with a single charge block. In some embodiments, the charge block includes a plurality of chambers and a plurality of projectiles positioned within the plurality of chambers.

Claims (33)

1. A charge block assembly for a firearm system comprising:

a charge body including a plurality of side-by-side chambers;

a plurality of projectiles, each of the plurality of side-by-side chambers comprising at least one of the plurality of projectiles;

wherein the charge body is configured and arranged to be fed into a feedport of the firearm system to enable a discharge of the plurality of projectiles from all of the plurality of side-by-side chambers simultaneously; and

wherein the charge body comprises coupled and/or integrated bobbins.

2. The charge block assembly of claim 1 , wherein the charge body comprises a fiber reinforced epoxy composite.

3. The charge block assembly of claim 1 , wherein the bobbins include a reinforcement cylinder comprising a wound continuous strand aramid and/or a carbon fiber epoxy composite.

4. The charge block assembly of claim 1 , wherein each bobbin comprises at least one of the plurality of side-by-side chambers.

5. A charge block assembly for a firearm system comprising:

a bobbin comprising:

a bore,

a propellant chamber,

a projectile, and

a propellant;

wherein the projectile is positioned within the bore;

wherein the projectile comprises a first end positioned adjacent to the propellant;

wherein at least a portion of the bobbin is wound with a winding; and

wherein the winding is configured to form a reinforcement cylinder encasing the propellant chamber.

6. The charge block assembly of claim 5 ,

the bobbin further comprising an alloy;

wherein the alloy is wound with the winding.

7. The charge block assembly of claim 5 ,

wherein the winding is a continuous parallel orientation winding.

8. The charge block assembly of claim 5 ,

wherein the winding is a filament comprising an aramid and/or a carbon fiber polymer composite.

9. The charge block assembly of claim 5 ,

further comprising a charge block main body;

wherein the charge block main body comprises a plurality of the bobbins; and

wherein the charge block main body comprises a wrapping comprising reinforcement bands.

10. The charge block assembly of claim 9 ,

wherein the main body comprises a polymer; and

wherein the polymer is between and around the plurality of the bobbins;

wherein the polymer forms a surface of the charge block main body.
