The B&T APC (Advanced Police Carbine) is a family of submachine guns and rifles produced and manufactured by B&T (formerly known as Brügger & Thomet) of Switzerland.

[2] The APC series was designed in the 2000s, as a modern submachine gun that would be cheaper to produce than the intermediate cartridge assault carbines that were seeing an increase in military usage during this period.

[4] On March 29, 2019, B&T was awarded a contract in the U.S. Army's Sub Compact Weapon Production-Other Transaction Agreement (P-OTA) competition for its APC9K submachine gun.

The $2.6 million contract included an initial 350 subcompact weapons (SCW) with an option for additional quantities of up to 1,000 SCWs, with slings, manuals, accessories, and spare parts.

The APC PRO series has the capability to have different calibre options, stocks, suppressors, accessories, training versions and the ability to accept either Glock or SIG P320 magazines, giving the platform vast modularity for its operators.
