Patent attributes
An upper receiver assembly for an AR style rifle is provided. The upper receiver assembly includes an upper receiver body with a channel formed in a side of the body. Further, the assembly includes a bolt carrier operatively coupled within the upper receiver body. A bolt is coupled within the bolt carrier, wherein a cam pin is coupled to the bolt and extends through an aperture of the bolt carrier. The assembly also includes a side charger having a charging handle that extends through the channel of the upper receiver body. The side charger also includes a bolt carrier engagement member. The bolt carrier engagement member engages the bolt carrier and moves the cam pin in response to pulling the charging handle toward the butt stock of the weapon. This results in charging the rifle.
