The Spandau Arms S2 is a 12 Gauge semi-automatic shotgun built on an inertia-driven action with a 24-inch vent rib barrel. It comes finished in a Mossy Oak Obsession hydro-dip pattern over a synthetic stock, with a rubber recoil pad and a 2.75-inch chamber. The receiver is drilled and tapped in the Benelli M2 pattern for mounting optics.

Detailed Features 

• Inertia operating system cycles a range of 12 Gauge loads without a gas system to clean. 
• Benelli Mobil-pattern choke tubes are included, covering Cylinder, Modified, Extended Ported Modified, and Full. 
• Fiber optic front sight with a brass mid-bead helps with fast target acquisition in the field. 
• Open-cut loading gate, enhanced lifter, and an oversized charging handle make the action easier to run with gloves on. 
• Synthetic stock ships with a drop and cast spacer kit plus a rubber recoil pad for fit adjustment and recoil control.

Shooters who pick up the Spandau S2 mostly compare it to other inertia-driven autoloaders in the same price range, and the general take is that it cycles reliably once broken in, though a handful of owners mention needing a few boxes of shells to smooth out cycling with lighter loads. The Mossy Oak Obsession finish gets consistent praise for looking sharp out of the box and holding up to field use without the coating flaking.

In the field, the 24-inch barrel keeps the S2 quick to swing on birds flushing at close range, and the synthetic stock with the drop and cast spacer kit is popular with owners who need to adjust fit without buying an aftermarket stock. The oversized charging handle and enhanced loading gate make reloading with gloves noticeably easier, which hunters who shoot in cold weather bring up often.

On value, the S2 is generally seen as a budget-friendly way into a Benelli-pattern gun, since it accepts Benelli Mobil chokes and mounts optics on the same M2 footprint. Some owners note the fit and finish isn't quite at the level of the guns it's patterned after, but most consider it a fair trade for the price.
