Bersa BAR9 AR9 9mm Pistol | 4″ Barrel | Compensator

The Bersa BAR9 / AR9 is an AR-style 9mm pistol built around a 4-inch barrel and KAW Valley XL compensator in a matte black finish. It uses a Picatinny optic footprint and an M-LOK handguard for accessory mounting; a compact red-dot such as a Holosun 507K pairs well and remains comfortably under $1,000. This platform suits range training and PCC-style competition where controllable, low-recoil performance and magazine compatibility with Glock-pattern magazines are practical advantages.
