Kel-Tec KSG-25, Pump Action Shotgun, 12 Gauge, 3 Chamber, 30.5 Barrel, Black Finish, Synthetic Stock, Magpul MBUS Front and Rear Flip Up Sights, Magpul RVG Rail Vertical Grip, 12+12 Rounds KSG25BLK The KSG-25 is no ordinary KSG. Its extended dual tube magazines hold twenty 3 inch, 12 gauge shells (plus one in the chamber), with the flexibility of switching between various projectiles. A patented downward ejection system makes it truly ambidextrous, while its 38 inch overall length, and 30.5 inch cylinder bore barrel still makes it more compact than a traditional style shotgun that holds a fraction of the amount of ammo.
