"The third generation of the wildly popular SUB2000, the Kel-Tec SUB2000 Gen3 Semi-Auto Pistol-Caliber Carbine offers folding convenience and Glock magazine compatibility. Unlike other folding carbines, the SUB2000 Gen3 folds in half without disturbing the optic thanks to its rotating forend. The simple folding mechanism and positive locking system keeps your optic zeroed and ready to go when you need it. It tucks neatly inside a backpack or under a seat, but unfolds in seconds to deliver superior ballistic performance with standard 9mm ammo thanks to its 16.15"" barrel. Like its forebears, the Gen3 operates via a simple and robust straight blowback action that's incredibly reliable. The stock is fully adjustable for fit, and the M-LOK forend provides plenty of space for accessories. Upper and lower Picatinny rails make it easy to attach a red dot and foregrip or light. Uses common G17/G19 magazines.
