Silver Shadow, makers of the double-barrled Gilboa AR, have developed a 9mm submachine gun. The Gilboa’s lower receiver is almost identical to the AR-15 lower receiver, although the magazine well has been shortened to accommodate Glock-compatible magazines.

The upper receiver contains a blowback system. It features, strangely enough, both a side charging handle and an AR-15-style rear changing handle.
