The KelTec Sub2000 Gen 3 5.7x28mm green carbine (KelTec part no. SUB2K57GRN) is the third generation of the semi-automatic carbine that folds in half, optics and all. Its rotating forend makes it an optics-ready carbine you can put an optic on and leave it there, folded or deployed. The 16.1-inch barrel gives 5.7x28mm ammunition the velocity and accuracy at distance that a handgun barrel cannot. Folded, it tucks away where space is tight, and it deploys quickly when time matters.
