The top half of an AR-15 rifle, incorporating an integral carrying handle and sights, houses the bolt carrier group and barrel. This configuration offers a classic, recognizable profile and provides a built-in sighting system. A fixed handle design often appeals to those seeking a more traditional aesthetic and provides a rigid platform for mounting optics.
This integrated design provides a stable sighting plane, reducing the potential for movement or misalignment between the receiver and sights. The fixed carry handle system offered a compact, self-contained solution popular in earlier AR-15 iterations. It remains a practical choice for shooters who prioritize simplicity and durability, eliminating the need for separate mounting hardware or concerns about optic compatibility. The inherent elevation over the bore axis offered by this design necessitates specific sighting considerations for different ranges.
