The Shockwave’s heavy-walled steel barrel is cut with a fixed cylinder bore for consistent patterns and full compatibility with both 2½- and 3-inch .410 shells. A single brass bead front sight gives a clear reference without adding bulk.
Anodized aluminum alloy keeps the receiver light yet durable. Dual action bars work with the corn-cob polymer forend for smooth cycling, and the drilled-and-tapped receiver now wears a six-slot rail, ready for optics or lights.
The bird’s-head polymer grip and compact 14.375-inch barrel keep overall length greater than 26 inches, allowing the firearm to remain a non-NFA item while maintaining maneuverability. At 4.24 pounds unloaded, it is easy to handle in tight quarters.
Mossberg’s ambidextrous top-mounted safety is intuitive for both right- and left-handed users. Combined with the 5+1 capacity, this Shockwave offers practical firepower in a lightweight, streamlined package.
