The Kel-Tec Sub-2000 Gen3 is a semi-automatic pistol-caliber carbine chambered in 9mm Luger, built around a 16.1-inch threaded barrel. This Multi Mag version folds in half at the receiver for compact storage or transport and is finished in Tan/Black. It is designed to run with more than one magazine pattern, giving owners flexibility in which pistol magazines they feed it, and it ships with a 15-round magazine for a 15+1 capacity.

The Sub-2000 has a reputation among owners for being a simple, reliable blowback design that keeps running with minimal cleaning. Some report the polymer furniture feels less refined than a metal-receiver carbine, but most consider that a fair trade for the folding feature and low weight.

Folding in half is the headline feature owners talk about, since it lets the Sub-2000 fit in a backpack or truck console. The threaded barrel makes muzzle device use popular on this platform. A common complaint is that the stock trigger has noticeable takeup and could be crisper out of the box.

The Multi Mag version's ability to run more than one magazine pattern is frequently cited as the reason buyers pick it over the single-mag Sub-2000, since it avoids being locked into one brand's magazines. Aftermarket support for optics mounts, magwells, and stocks is broad, and owners generally view the rifle as good value relative to other folding carbines.
