B&T APC9K Pro: 21st Century SCW

The APC9K Pro is the first SMG adopted by the U.S. Army since the WWII-era Grease Gun, and the winner of the 2019 Subcompact Weapon contract. Compact, controllable, and combat-proven, the APC9K Pro earned rapid follow-on adoption across multiple U.S. military branches and federal agencies for good reason.

Built on the same trusted architecture as the standard APC9, the “K” (Kurz) variant shrinks the package without sacrificing capability. A 4.3" cold hammer-forged barrel, 12.5" OAL, and ½x28 threaded muzzle with optional Tri-Lug adapter give users flexibility for suppression, tight-quarters maneuverability, and rapid deployment in low-visibility environments.
Inside, the APC9K Pro carries all the hallmarks of the APC line:
• Monolithic aluminum upper for strength and reliability
• Dual, auto-folding, non-reciprocating, ambidextrous charging handles
• Hydraulic recoil mitigation for minimal muzzle rise—even one-handed
• Modular, non-serialized lowers compatible with B&T, Glock, SIG P320, and MP5 mags
• AR-pattern grip & trigger compatibility
• Full B&T stock/brace ecosystem, including Tele-Stock, MBT Folding Stock, and buffer-tube adapter options
• NATO rails + M-LOK compatibility for lights, optics, slings, and mission-specific accessories

Trusted by professionals. Valued by civilians. Whether for duty, defense, vehicles, or discreet deployment, the APC9K Pro delivers full-size performance in a short-format SMG — precision, portability, and proven performance in one compact platform.
