side charging upper 308

A side-charging upper for a .308 (7.62x51mm) rifle refers to a design where the charging handle is located on the side of the upper receiver, as opposed to the traditional rear location. This allows for easier access and operation of the charging handle, especially when using optics or other accessories that may obstruct or limit rearward movement.

Side-charging uppers for the .308 are available from various manufacturers and can be used with compatible lower receivers to build a complete rifle. Some popular options include Aero Precision, Mega Arms, Gibbz Arms, and JP Enterprises, among others. It's important to ensure compatibility between the upper and lower receiver before purchasing or building a rifle.
