Kel-Tec Sub2000 Kel Sub2K57Grn S2K5.7 5.7X28 16.15 20R Grn

The Kel-Tec Sub2000 in 5.7x28mm is a compact, lightweight rifle built for shooters who want controllable recoil and reliable performance in a package that stows anywhere. Chambered in the modern 5.7x28 cartridge—known for its flat trajectory and mild recoil impulse—this blowback-operated rifle delivers accurate, repeatable shooting whether you're at the range, in the field, or training for precision. At just 4.36 pounds unloaded, the Sub2000 won't tax your shoulders or pack, and its folding design collapses to 16.15 inches for storage in a bag, truck, or closet.

The Sub2000's polymer frame keeps weight down without compromising reliability. Its simple blowback action is easy to field-strip and maintain—no gas tube or piston to worry about. The rifle ships with a 20-round FN Pro Magazine, giving you practical capacity for extended shooting sessions or training drills. Integrated M-LOK slots and Picatinny rails give you the freedom to add optics, lights, slings, or other accessories to match your mission.

Built for shooters who value practicality and don't need the bulk of a traditional rifle, the Kel-Tec Sub2000 5.7x28 is equally at home as a truck gun, range trainer, or backup rifle. The 5.7x28 round itself cycles smoothly through the Sub2000's design, delivering the low-recoil characteristics that make rapid, accurate follow-up shots manageable for most shooters.
