Kel‑Tec SUB-2000 Defender Gen 3 9mm 16.15in 15rd Black

About this product

The Kel‑Tec SUB-2000 Defender Gen 3 is a compact, folding 9mm carbine engineered for portability and practical use. Its design allows the carbine to fold in half for reduced transport and storage length while preserving zeroed optics through a reinforced forend and rail integration. The platform uses a straight blowback semi-automatic system and accepts common Glock 17 and 19 magazines for broad parts availability. Standard fitments on this configuration include a Viridian RFX11 green-dot optic and Magpul flip-up sights to support fast target acquisition and everyday utility.
