Abstract

Provided is a side charging handle system for an AR-pattern firearm with an upper receiver having an internal longitudinal bore for receiving a bolt carrier assembly for longitudinal reciprocation therein, a side longitudinal guide slot, and a side charging handle having an engagement pin extending through guide slot to engage the bolt carrier assembly.

Claims

1. A side charging handle system for an AR-pattern firearm, comprising:

an upper receiver configured to attach to a standard AR-pattern lower receiver and having an internal longitudinal bore for receiving a bolt carrier assembly for longitudinal reciprocation therein, a side longitudinal guide slot, and;

a side charging handle having an engagement pin extending through guide slot to engage the bolt carrier assembly; and

the bolt carrier assembly including a bolt carrier body with an engagement pin socket configured to cause rearward movement of the bolt carrier assembly when the charging handle is retracted to the rear in the side longitudinal guide slot while allowing the bolt carrier assembly to retract independently of the side charging handle.

2. The charging handle system of claim 1, further comprising a first guide track on the upper receiver substantially parallel to the longitudinal guide slot and the charging handle including a sliding cover having a second guide track that engages first guide track for sliding movement thereon and that substantially covers the longitudinal guide slot when the charging handle is in a forward position.

3. The charging handle system of claim 1, wherein the side longitudinal slot includes a detent recess adjacent a forward end and the engagement pin is spring biased into releasable engagement with the detent recess.

4. The charging handle system of claim 1, wherein the engagement pin socket is a recess open in a forward direction.
