Kel-Tec SUB2000 Gen3 | 5.7x28mm | 16.15″ | 20rd | SUB2K57BLK

The Kel-Tec SUB2000 Gen 3 is a compact, folding semi-automatic carbine chambered for 5.7x28mm that emphasizes portability and modularity. It features an updated action with an ambidextrous bolt hold-open, a rotating forend that allows optics to remain mounted while folding, and a visual chamber indicator. The rifle accepts compatible 20-round FN 5.7 magazines and includes M-LOK and Picatinny attachment points for accessories. For a cost-effective optic that pairs well with the SUB2000 for close-to-mid-range work, consider a 1-6×24 variable such as the Vortex Strike Eagle series, which stays well under $1000.
