Here's a custom, suede-lined, leather scabbard for the Mossberg Shockwave. It's made from genuine American Hermann Oak Leather and lined with a super smooth chocolate brown chap suede. The mounts on the outside are secured with mechanical fasteners (not rivets). The hardware does not contact the firearm. The 'D' rings (6 total) are removable leaving a strap slot for horizontal lashing options.
