A covered storage compartment in the butt holds batteries, cleaning patches, or small tools. A fixed cheek piece provides a consistent cheek weld height for aiming.

The rubber buttpad provides a non-slip surface against the shoulder and adds a small amount of recoil absorption compared to a bare polymer buttpad.
