The Kel-Tec KSG-25 is a bullpup pump-action 12 GA shotgun with a 30.5-inch cylinder-bore barrel, dual-tube magazine system, and OD Green finish over a salt bath nitride receiver. The two tubes hold either 10+10 rounds of 3-inch shells or 12+12 rounds of 2-3/4-inch shells, with one round in the chamber.

Detailed Features 

The bullpup layout puts the action behind the trigger group, so the 30.5-inch barrel fits in a 38-inch overall package, significantly shorter than a conventional pump gun with the same barrel length. The dual-tube selector lets the shooter switch between tubes to change ammunition type mid-string without unloading. 
 
Upper and lower Picatinny rails accommodate optics, lights, and vertical grips. The cross-bolt safety is centrally located. Magpul MBUS front and rear sights are included as a factory baseline. The salt bath nitride receiver finish is harder and more corrosion-resistant than conventional bluing.

The KSG-25 draws consistent discussion around two features: the 24-round capacity and the bullpup configuration. The round count is the headline for most owners. Being able to carry that much ammunition in a self-contained pump shotgun at 38 inches overall is genuinely unusual, and the dual-tube selector that lets shooters switch between buckshot and slug tubes without unloading is practically useful.

Reliability gets mixed reviews. Most owners report solid function with common loads, but cycling sensitivity to specific ammunition types and occasional feeding issues come up regularly enough to be a legitimate consideration. This is a known characteristic of the KSG platform that prospective buyers should research before purchase.

Ergonomics generate split opinion. The bullpup control placement feels natural to some shooters and awkward to others, particularly the charging handle reach. At 9.25 lbs unloaded the gun is heavy, and the balance point shifts noticeably as the tubes drain. Picatinny rails and the Magpul sights are appreciated for out-of-box configuration options. OD Green finish is functional, and opinions on aesthetics vary.

For hunting, this shotgun has been easy to bring along. Its configuration is especially convenient when crossing a fence because it does not tend to catch or hang up. That practical handling advantage is what stands out most to me in the field. I appreciate equipment that stays manageable during the awkward parts of a hunt, and this has done that well. My positive rating is based on that straightforward usefulness rather than extra features or unsupported performance claims.
