The CBC Pump 12 Military/LE shotgun (a.k.a. Taurus ST-12)

The name of Brazil’s CBC (Companhia Brasileira de Cartuchos) is almost immediately associated with ammunition manufacture, since this has been the company’s main area of activities since it was founded by two Italian immigrants in São Paulo back in 1926. In the 1960s, however, industrial activities were expanded with the production of single-barrel, break-action shotguns, first exports to the United States being recorded in 1966 and eventually reaching over 1.5 million units in the years that followed. The year 1990 marked the actual internationalization of the company with the creation of the Magtech brand and wide distribution in foreign countries, consolidated in 2003 with the addition of a sales branch in Hamburg, Germany. In 2007, CBC acquired all the assets of the German military and LE ammunition manufacturer MEN, followed two years later by the acquisition of the renowned Czech Sellier & Bellot ammo maker. Little known, but of foremost importance, was the 2015 stock control acquisition of Forjas Taurus by CBC.

This 12-ga, single-barrel break-action shotgun with a 28in (700mm) barrel is a typical CBC weapon that has been widely exported to the U.S. and Europe. The gun was also available in other shotshell calibers.

Following that no-frills shotgun, the Brazilian company introduced a 12-ga (7+1, 3-in chamber) pump-action model that found good acceptance in the local and export markets, this including the military and LE sectors. This was mainly available for the civil market with a 24-in (610mm) barrel, while those intended for, say, police use could be supplied with shorter barrels. The weapon was later modified with the addition of a pistol grip and a fixed or foldable polymer stock, a choice f several Brazilian military and public security forces, having received the commercial designation CBC Pump Tactical.

The very standard CBC pump-action shotgun together with the stockless, pistol-grip variant.

The fixed-stockTactical model in use by an anti-riot unit (CiaPol – Companhia de Polícia, Police Company) of Brazil’s Corpo de Fuzileiros Navais (Marine Corps).

The CBC Tactical with foldable polymer stock is seen here together with a Condor AM 640 launcher for non-lethal, 37/38mm ammunition. Different types of 12-ga riot-control rounds are displayed alongside the shotgun. Both weapons are in current use by the BPChq – Batalhão de Polícia de Choque (Shock Police Battalion) of PMERJ – Policia Militar do Estado do Rio de Janeiro (Rio de Janeiro State Military Police).

The latest evolution of the CBC shotgun was displayed under the designation of Pump 12 Military 3.0 (a.k.a. the Taurus ST-12) in the recent LAAD 2017 Defence & Security show in Rio de Janeiro. The weapon is available with three different barrel lengths (14-in/355mm, 19-in/482mm, and 24-in/610mm), and is fitted with a six-position, length-adjustable polymer stock whose internal shock-absorption system is said to reduce felt recoil by around 50 per cent. Picatinny rails are provided on top of the aluminum receiver and may also be fitted to three sides of the magazine tube, except for the shorter (14-in) barrel version. Rear sight is an adjustable ghost ring, while the front sight is a prominent blade with side protections.

Chambered to the common 70mm-chamber, 12-ga round, the CBC Pump 12 Military offers three choices of barrel length, with overall lengths (stock fully extended) of 910, 1070, and 1160mm. Weights in the 3.2-3.7kg range.

Closer view of the receiver area, the ambidextrous applied safety button just aft of the trigger being noticeable. The adjustable stock, of aluminum/polymer construction, incorporates an internal shock-absorption system that substantially reduces felt recoil.

The business end of the CBC Pump 12 Military pump-action shotgun. All versions come with a cylindrical choke barrel, fully compatible with all 3” Magnum cartridges and anti-riot (less-lethal) rounds. Magazine capacity is seven for the longer-barrel versions, or six for the 14” barrel variant.

The shorty (14” barrel) CBC Pump 12 has a maximum length of 910mm with the stock fully extended, and weighs 3.2kg empty. No heat shield is fitted to the barrel of the example shown.

For a comparative purpose, this is a Taurus ST-12 prototype as under tests late in 2012. Note variations in sights, heat shield, adjustable stock, pistol grip and fore-end.

    AR buttstocks on shotguns are the worst, unless you need the reduced LOP due to armor.

    I’d rather stick a youth stock on it.

    If this was my shotgun, I would do that and take the heat shield amongst any other weight reduction options easily adapted.

    Then I ‘d buy a sheath if I was worried about pumping so many rounds that it is too hot to touch incorrectly.

      I’d rather just buy a decent shotgun in the first place

        Concurred.

        I still need youth stocks on my shotguns though. 🙁

    From a cursory glance, it looks like there aren’t any really questionable design decisions… not that I’ll hold my breath on that one.

    Whenever Taurus introduces something new, I keep wondering if it will be the one that runs like a top and finally redeems the brand. But I’m not holding my breath on that, either.

    It’s a damn shame, because the world needs more good, inexpensive guns.

    I love these articles , they are some of the best in here. Keep them coming. I only wish I could own some of these beasts.

    Remington 870 POLICE Model is THE shotgun to own for self-defense applications.
    I took an Remington 870 Express, added an AR-15 collapsible stock, a jagged edge door breach comp, composite stock and forearm, a 7 round side mounted ammo caddy and a heat shield. It is a 26″ barrel of terror packed perfection.
    I did not build it for anyone on this forum so if you do not like it, that is your prerogative.
    That is what makes this country great…freedom of choice.

    Nice looking gun, but I will stick with my Mossberg 930 tactical. Holds enough shells. Short enough for a truck gun. Can shoot with one arm/hand if needed. Faster shooting. And AMERICAN made.
