About this product

The Kel-Tec SUB2000 Gen 3 is a compact, folding semi-automatic carbine chambered in 5.7 x 28 mm designed for convenient storage and modular use. Its folding design reduces overall length for transport while maintaining a full-length barrel when deployed. The platform is built on a lightweight polymer receiver and offers integrated mounting options for optics and accessories. The Gen 3 updates include a rotating forend for optics retention, a chamber indicator, and an improved trigger and operating handle for easier manipulation.
