Kel-Tec Sub2000 Kel Sub2K57Tan S2K5.7 5.7X28 16.15 20R Tan

The Kel-Tec Sub2000 in 5.7x28mm is a compact, lightweight rifle built for shooters who value portability without sacrificing firepower. This tan polymer-framed carbine folds down to just 16.15 inches, making it one of the most packable centerfire rifles available—ideal for truck guns, backpack carry, or anyone who needs serious capability in a footprint that fits tight spaces. The 5.7x28mm cartridge delivers flat trajectory and minimal recoil, so follow-up shots stay on target and shooting stays comfortable even during extended range sessions.

Built on a proven blowback operating system, the Sub2000 strips down easily for field cleaning and runs reliably without fussy maintenance. The 16.15-inch barrel gives you velocity and accuracy without the bulk of a full-size rifle, while the 20-round FN Pro magazine keeps you well-supplied. At just 4.36 pounds unloaded, you'll barely notice it slung or stowed.

Kel-Tec equipped this rifle with integrated M-LOK and Picatinny rail sections, so you're not locked into factory sights—mount optics, lights, or foregrips to suit your mission. The tan finish works equally well in field use or as a truck tack driver. Whether you're looking for a truck gun, a suppressor host, or a rifle that won't wreck your pack, the Sub2000 5.7x28 delivers compact performance without compromise.
