About this product

The KelTec SUB2000 Gen 3 is a compact, folding semi-automatic carbine chambered for 5.7x28mm. Designed for portability and modularity, the SUB2000 Gen 3 features a polymer stock, a rotating forend that preserves optic zero when folded, and compatibility with FN-style 5.7 magazines. The straight blowback action and lightweight construction make it practical for transport, range use, and close-quarters applications where a compact, stowable carbine is desirable. Standard 20-round magazine capacity and integrated rail sections allow for straightforward accessory installation.
