The KH9 Covert is a testament to B&T’s commitment to innovation, and comes equipped with a massive amount of exclusive features. The KH9 Covert’s most notable features are its pistol grip and magazine well – both of which can be folded away in a 90° position. This makes the KH9 Covert’s already flat, low-profile design even more compact, making the weapon an excellent choice for use in confined spaces, as well as providing a convenient option for storage and transportation. The pistol grip and magazine well can be rapidly unfolded for instant deployment, and when the magazine well is unfolded, it will naturally guide the magazine into the chamber area. The KH9 Covert utilizes a newly designed 25 round magazine that allows the weapon to be as compact as possible while in the folded position, but is also compatible with any size of B&T APC9 polymer magazines.

Another prominent feature of the KH9 Covert is its safety and trigger system; the safety lever functions as a de-cocker for the internal hammer and the trigger has a double-action/single-action setup. These features are typically found on handguns, but are somewhat uncommon for carbines or PDW’s. In addition to its foldable design and unique trigger system, the KH9 Covert offers a wide range of customization options including top mounted picatinny rails for the installation of optics and iron sights, a bottom mounted picatinny rail for tactical lights/lasers, and a Tri-Lug adapter on the muzzle for use with a suppressor.
