Abstract

A lower receiver that may be right hand or left hand configurable is provided. The lower receiver includes a static ejector that can be easily configured for right hand or left hand positions within the same lower receiver and a magazine button assembly having a left magazine button and a right magazine button that are operatively coupled together so that either magazine button can be pushed to release the magazine. This allows the gun builder to use this one lower receiver to build a right or left handed rifle.

Claims (5)

1. A lower receiver comprising:

a magazine button assembly comprising:

a right magazine button comprising a pivot point and a protrusion extending from a location of the pivot point, the protrusion having a first hinge joint member, wherein the right magazine button includes a magazine engagement member; and

a left magazine button comprising a pivot point and a protrusion extending from a location of the pivot point, the protrusion having a second hinge joint member, wherein depressing the right magazine button or the left magazine button releases a magazine coupled to the lower receiver.

2. The lower receiver of claim 1 , further comprising a spring coupled between button ends of the right magazine button and the left magazine button, wherein the right magazine button and the left magazine button may be operatively coupled together with the first hinge joint member engaging the second hinge joint member to locate the hinge joint between the pivot points, and wherein pressing of the button end of the right magazine button or the left magazine button rotates the magazine engagement member away from a magazine to disengage the magazine engagement member.
