The Halo Side Saddle mounts to the top of the receiver using the existing screw holes. It uses a feature ATI calls "add-a-shell," an attachment that mounts to the side saddle and allows the user to customize shell storage.
The Halo Side Saddle system ships with six or nine add-a-shells. A six-inch Picatinny top rail enables the mounting of an optic.
The Halo Side Saddle, Picatinny top rail, and add-a-shell attachments are CNC machined from military Type III anodized 6061 T6 aluminum.
The Halo Side Saddle will ship to select stores beginning this month.
