Eschaton-Archwell QCS-21 Perforator

21-shot 12 gauge quad chamber semi-automatic shotgun.
Archwell Defense variant.

The end result of the amalgamation of multiple failed designs such as the SG-3/7, AMBAS-12, and the SA-1220. As the name indicates, it is a quadruple chamber shotgun with a massive capacity of 21 shells - 20 in the chambers, and one loaded in the gun.

The QCS-21's appeal is its methods of reloading. There are two methods of reloading: One, is to reload the chamber magazine manually, with the chambers spinning counter clockwise for every shell loaded. Two, and the quicker of the duo, is ejecting the tube magazine and loading a new one, similar in fashion to the Model 1216.

Most of the fancy machinery is hidden in each magazine, which makes magazine production and accessory logistics difficult without the proper resources.

The user can switch to pump-action by pressing a button selector near the pump handle. This allows the gun to chamber more powerful shells at the expense of fire rate.

There is a shortened variant, the QCS-21/S, designed for assault and boarding teams.
