The B&T SPC9 is a versatile, lightweight 9mm carbine developed to meet a European police tender for a firearm with AR-style ergonomics. Combining features from the B&T APC9, MP5, and AR platforms, it offers a well-balanced, low-recoil shooting experience, thanks to its hydraulic buffer system. The SPC9 is built around a cold hammer-forged barrel, available in 4.5-, 6.5-, 9-, and 16-inch lengths, ensuring accuracy and durability. It features dual charging systems—an AR-style T-handle and a non-reciprocating, folding charging handle above the barrel—allowing users to choose their preferred manual of arms. The ambidextrous lower receiver is compatible with various magazines, including Glock and SIG P320. Non-SD models feature a tri-lug suppressor mount for rapid attachment. The SPC9 is available in pistol, short-barreled rifle (SBR), and rifle configurations, with the SBR variant featuring a 9-inch barrel and retractable stock. Safety is enhanced with a European-style system allowing the selector to be engaged with the hammer forward. A two-stage trigger provides a smooth pull, and the modular design allows for customization. Standard accessories include backup sights, a sling, a cleaning kit, and a soft case. Designed originally for law enforcement, the SPC9 is available only in semi-automatic, with SPC10 and SP45 variants chambered in 10mm and .45 ACP.
