Four New Box-Magazine-Fed Shotguns

At the 2017 SHOT Show, we got a first look at the SKO-12 shotgun from Standard Manufacturing. You might know them as the manufacturers of the double-barrel pump shotgun, the DPS-12.

The SKO-12 is a box magazine fed, semi-auto shotgun with AR-pattern controls. Now, here’s the thing about magazine fed semi-auto shotguns…they always seem to run into problems. There’s something about scaling up an action to handle those big fat, flat-fronted shotgun shells that makes them bind up.

Of course, there are some good ones out there as manufacturers are slowly getting over the hurdles plaguing the design, and from this GunsAmerica review above from Clay Martin, it looks like the SKO-12 fits that bill. Let’s take a look at it’s specs and some of the newest box-magazine fed semi-auto shotguns on the market.

The SKO-12 has a layout that will be istantly familiar to AR shooters, meaning a short learning curve. The company also has a Shorty version of the SKO on it's website with no stock and an 18-inch barrel, for an overall length of just-legal 26-inches, and no top rail. There was also a bullpup version of the SKO on display at SHOT Show, though it was not available to shoot and is still listed by the company as unavailable.
