Kel-Tec S2K-Multi Rifle 9mm Luger 15rd Magazine 16.1" Barrel Green

The Kel-Tec S2K-Multi is a compact 9mm carbine that trades traditional rifle footprint for genuine portability without sacrificing firepower. If you've ever wished for a rifle that actually fits in a backpack, truck bed, or safe without eating up half the space, this folding 9mm rifle is built for exactly that problem. Chambered in 9x19mm Luger, it accepts standard G19/G17 Glock handgun magazines, so if you already run Glock pistols, your ammunition ecosystem stays unified—a real advantage on the road, at camp, or during extended field time. The 16.1-inch barrel keeps velocity respectable for the caliber while the rifle's compact profile makes it ideal for overlanders, backpackers, and anyone who needs a capable long gun in tight quarters.

What makes the S2K-Multi genuinely different is the fold. When the rear stock folds forward against the barrel, overall length drops to just over 16 inches—short enough to stash in places a traditional rifle simply cannot go. That flexibility means this isn't a novelty; it's a working tool for situations where space and weight matter. The 5-pound trigger is manageable for shooting discipline, and the gun strips down without tools if you need to clean or inspect it in the field. At 4.2 pounds unloaded, it won't slow you down during a backcountry push or a long day in the truck.

The green finish gives it a utilitarian look that suits its purpose—this is a rifle built for function, not show. Whether you're equipping a truck gun, a hiking rifle, or a backup long gun, the S2K-Multi's blend of capacity, compatibility, and compactness covers genuine use cases where full-size rifles fall short.
