- Receiver-mounted 4-round shell carrier (installed)
The 14.375 in heavy-walled steel barrel with a true cylinder bore delivers strength and simplicity, guided by a brass bead front sight. The matte blue finish complements the aluminum receiver and black synthetic furniture, including the bird's-head grip and ribbed corncob forend with an embroidered MOSSBERG strap.
The action features non-binding twin action bars, steel-to-steel lockup, dual extractors, and an anti-jam elevator for consistent cycling. Controls include an ambidextrous tang-mounted safety, a right-side ejection port, and a bottom loading port.
Chambered for both 2.75 in and 3 in 20-gauge shells, the tubular magazine provides a 5+1 capacity. A scaled 20-gauge receiver and reduced-size forend help keep overall weight to approximately 4.95 lb while maintaining a compact overall length of 26.37 in.
The factory receiver comes drilled and tapped. Practical touches include sling studs on the magazine cap and grip. The installed receiver-mounted 4-round shell carrier adds on-board shell storage to this already capable Shockwave configuration.
