Brügger &amp; Thomet APCBrügger &amp; Thomet APC Brügger & Thomet APC The B&T APC (Advanced Police Carbine) is a family of firearms produced and manufactured by B&T (formerly known as Brügger & Thomet) of Switzerland. Announced in 2011, the submachine guns series uses standard 9×19mm (APC9), .40 S&W (APC40), 10mm Auto (APC10) and .45 ACP (APC45) ammunition. History and overview. 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. Before this point, B&T sold the MP9 and had experience in  the manufacture of submachine guns, as well as years of feedback from customers on possible enhancements. The first B&T APCs were produced in 2011. In March 2019, B&T released its APC9 PRO series, an improvement with a non-reciprocating charging handle and a replaceable pistol grip, compatible with grips for the AR-15 style rifle family of firearms. The APC9 PRO features an optional lower receiver capable of using Glock magazines. 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. Design. The APC uses a straight blowback gas system. The addition of a proprietary hydraulic buffer system in the receiver back plate helps control recoil. More than 50% of the APC's parts are interchangeable between the different platforms. The APC's upper receiver is made from aerospace-grade alloy, and the lower receiver, pistol grips, magazine, and butt stock are made from polymer. The APC uses the same magazines  as the MP9. The APC's mechanical sight is composed of an adjustable ghost ring type rear sight and a cylindrical sight. Sights can be folded in the base when not in use, and will pop out quickly when in use. The APC has an H&K MP5 style locked lugs-style barrel and can be equipped with a quick-release suppressor or flash hider. The APC45's barrel comes with a flash hider by default. The APC shares a side-folding polymer stock with the B&T GL-06 grenade launcher. The trigger assembly is effectively the same as the AR-15/M16  rifle, and accepts many after-market replacement parts. The entire weapon, including the charging handle, are ambidextrous, and can be adjusted based on the operator's handedness. Variants. The APC submachine gun is offered in several variants. The standard submachine gun has a barrel length of and the carbine variant has a barrel for the civilian market. All variants are available in 9×19mm (APC9) and .45 ACP (APC45) calibres. 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.
