The 14.5 inch heavy-walled barrel is set up for durability and control, featuring a true cylinder bore, a stand-off/breacher muzzle device, and a ventilated heat shield. A brass bead front sight provides a straightforward aiming reference.
The pump-action system uses twin action bars, a steel-to-steel lockup, and an anti-jam elevator. The receiver is anodized aluminum with a matte blued/black overall finish for a uniform, low-glare appearance.
Furniture is purpose-driven: a synthetic Raptor birds-head grip for a secure hold and a polymer corncob forend with a web strap to aid control during cycling. The design reflects the Shockwave configuration with compact dimensions.
Capacity is 4+1 with a 3 inch chamber, and overall length is approximately 26.37 inches with an approximate weight of 5.75 lb. The tang safety is positioned for intuitive operation, and the receiver includes a scope mount. Rails are present per the SPX specification details.
