The APC9K SD2 was a submission to the United States Army as a demonstration of available technology for its Sub Compact Weapon (SCW) trials; one that offered unseen advancements in compactness, ergonomics, and integral, scalable suppression. Ultimately, B&T USA’s APC9K was selected and awarded the U.S. Army’s SCW contract as it presented exactly what the U.S. Army required for its mission.

At less than 15-inches in overall length, the APC9K SD2 is the shortest integrally suppressed submachine gun currently available; optimized for low visibility carriage and discreet deployment; while delivering unsurpassed accuracy, controllability, and ergonomics. With its advanced, scalable suppressor system, the SD2 is the solution for your future mission.
