The Kel-Tec KSG is a 12-gauge pump-action shotgun in a bullpup layout, with the action and dual magazine tubes positioned behind the trigger. That arrangement trims overall length to 26.1 inches while keeping an 18.5-inch barrel. The dual tubes hold up to 6+6+1 rounds of 2.75-inch shells (or 7+7+1 of 1.75-inch mini-shells). A selector lever lets the shooter switch between tubes mid-use, making it possible to keep different load types — buckshot in one, slugs in the other — ready to go. A Picatinny rail runs the top for optics; a lower rail accepts grips or lights. Controls are ambidextrous.
