Kel-Tec Sub2000 GEN3 9mm Luger 16.15in Semi Automatic Modern Sporting Rifle - 15+1 Rounds - The 9mm SUB2000 GEN3. The most significant new twist? Literally, the single twist-and-fold motion of the patent-pending rotating forend. Release the barrel assembly with a button, twist the forend in either direction and snap it into place. Other GEN3 updates include many “quality of life” improvements such as an aluminum trigger, lightened trigger pull, and an ambidextrous bolt hold-open. Plus, a redesigned operating handle with a new easy-pullback action and yes, it still takes Glock mags.KELTEC
