Mossberg 590 Shockwave 20 Gauge Pump Action Shotgun

Description

The Mossberg 590 Shockwave is a 20 gauge pump-action shotgun listed for home-defense applications. It uses a 3 inch chamber, a blued finish, and a black Raptor grip with a strapped forend. We see this configuration as a straightforward option for shooters who want a compact pump-action platform with familiar controls and fixed sights.
