S&W M&P12 Bullpup 12 Gauge Shotgun

The Smith & Wesson M&P12 is a modern pump-action bullpup shotgun introduced by Smith & Wesson in 2021, chambered for 12-gauge shells, the shotgun features a compact bullpup configuration, pretty much similar to the KSG12 or the DP12 shotgun.

The tubes can be swapped by the press of the button near the fore, with the ability to also unload the shells via the press of the ease-load button (for the context of H3, we'll just dump all rounds)

Features

• Bullpup shotgun with double tube magazine
• Switch the magazine on the fly, with the ability to also unload rounds from the tube with a press of a button
• Can take both picatinny or MLOK attachments, with a hidden rail to swap out the standard grip with your own. Also can take muzzle devices
• Rear stock can be extended to reveal the chamber, meant for clearing jams apparently.
• Can be found in Firearms > Tube-Fed Shotgun
