Abstract

A modular firearm is disclosed. The firearm that can be configured to operate using ammunition of different calibers via interchangeability of only a few parts. The firearm includes a foldable butt stock assembly for quickly and easily converting the firearm from an extended operating configuration to a compact transport configuration, and vice-versa. Additionally, the firearm includes a modular hand guard assembly having multiple mounting platforms for accommodating a variety of different accessories.

Claims

1. A modular firearm system, comprising:

a receiver;

an interchangeable barrel assembly mountable to the receiver and including a barrel defining a chamber adapted to receive a round of ammunition therein;

a fire control for firing the round of ammunition;

a reconfigurable magazine adapted to supply ammunition of different sizes and/or calibers to the chamber; and

a bolt assembly received within and movable along the receiver, the bolt assembly including a bolt body having an axial bore extending therethrough and an interchangeable bolt head releasably mountable within the bolt body;

wherein the barrel can be exchanged for a barrel having a chamber adapted to receive ammunition of a different size and/or caliber, the bolt head removed from the bolt body and replaced with a bolt head adapted to engage the ammunition of a different size and/or caliber, and the magazine reconfigured to supply the ammunition of a different size and/or caliber to effect a change in size and/or caliber of the ammunition to be fired by the firearm.

2. The firearm of claim 1, further comprising a transverse bore formed in the bolt body, and a locking member received in the bore and engaging the bolt head for releasably securing the bolt head to the bolt body.

3. The firearm of claim 2, wherein the locking member further comprises an axial bore formed through at least a portion of the locking member for enabling passage of a firing pin therethrough.

4. The firearm of claim 1, further comprising a bolt stop mounted at a rear portion of the receiver, the bolt stop including a bolt stop lever movable between first and second positions for engaging and guiding a linear movement of the bolt assembly and selectively limiting movement of the bolt assembly.

5. The firearm of claim 4, wherein the bolt body includes a guide channel, and wherein the bolt stop lever further comprises a guide arm adapted to engage the bolt body along the guide channel thereof.
