Companhia Brasileira de Cartuchos S.A. · Shotgun · In Production · 2017
Also known as: Taurus ST-12, CBC Pump Tactical, CBC 586
Overview
The CBC Pump 12 is a Brazilian pump-action shotgun developed by Companhia Brasileira de Cartuchos for military, law enforcement, and civilian markets. Chambered in 12 gauge with a 70mm (and 3-inch magnum-capable) chamber, it feeds from a tubular magazine holding six to seven rounds depending on barrel length. The design uses an aluminum receiver with integrated Picatinny rails, a six-position adjustable polymer stock with an internal shock-absorption system that cuts felt recoil by roughly half, and ghost-ring sights. Offered with 14-inch, 19-inch, and 24-inch cylinder-choke barrels, it accepts standard buckshot, slug, and less-lethal anti-riot loads.
