context_page_description: The CZ 805 BREN modular rifle is a gas-operated selective fire self-loading rifle with a rotating breechblock and cold hammer forged chrome lined barrel manufactured by CZUB. The modular design currently enables users to change the calibre of the weapon to 5.56×45mm NATO or 7.62×39mm intermediate cartridges by quick change of barrel with gas tubes, breech block, magazine bay and magazine.
  The CZ 805 BREN, CZ 807, CZ BREN 2 and CZ BREN 2 BR were created by Česká zbrojovka Uherský Brod in 2006 to replace the Sa vz. 58 in the Czech Army.
  The CZ 805 BREN is used by the Czech military, Indonesian special forces and Mexican police. In 2014, Slovak Army began to replace its vz. 58 rifles with CZ 805 BREN. In November 2016, the Czech Army received its first batch of CZ BREN 2 modular assault rifles. In 2017, French GIGN received 68 CZ BREN 2 assault rifles chambered in 7.62×39mm and is expected to order more, in order to replace most of its Heckler & Koch HK416. The CZ BREN 2 in 7.62×39mm was also issued to Egyptian airborne forces and Republican Guard in 2017 and 2018 respectively.
context_section_description: For the domestic Army Replacement Rifle program development, the Lada was re-designated Project 805. The Army still did not wish to buy a new rifle for the entire military, but special forces did receive Bushmaster M4A3 carbines. With the prospect that the Army would re-arm gradually rather than on a large scale, CZUB drew up entirely new specifications in late 2005. Project 805 became the CZ XX, and then the CZ S805.
  Two types of guns were drawn up: 'A' models chambered for intermediate rounds including 5.56×45mm NATO, 7.62×39mm, and 6.8mm Remington SPC; and 'B' models chambered for rifle rounds like 7.62×51mm NATO and even .300 Winchester Magnum.
  All had three barrel lengths to act as a rifle, close quarters carbine, and designated marksman rifle/LSW. A CZ S805 was presented to the Army chief of staff in November 2006, but still was not ordered. CZUB then presented the weapon publicly and spent three years showing it at exhibitions. It wasn't until November 2009 that the Czech Army finally released a tender for a new infantry rifle.
  The company reduced its modularity for the competition and submitted a 5.56 mm rifle (A1) and 5.56 mm carbine (A2), as well as similarly configured 7.62 Soviet-chambered guns. This was eventually reduced to just the 5.56 mm system. When the tender was released, 27 weapons were submitted, but were reduced to just the CZ 805 and FN SCAR-L. The CZ 805 won narrowly from emphasis on a domestic design and the result was made public on 1 February 2010. FN Herstal did not contest the decision, and the CZ 805 was officially ordered on 18 March 2010: 6,687 CZ 805 BREN A1 assault rifles; 1,250 CZ 805 BREN A2 carbines; and 397 CZ 805 G1 proprietary grenade launchers. Every one was equipped with Meopta ZD-Dot red dot sights and iron sights. For special forces, 1,386 enhanced optical suites consisting of Meopta's DV-Mag3 daylight 3× magnifier, NV-3Mag night 3× magnifier, and a DBAL-A2 (AN/PEQ-15A) laser target designator were also ordered.
  In May 2010, the Army requested changes to the design before it could be operational including the change from a folding and telescoping stock to just a folding one, a pin-stabilised magazine well, a pistol grip with changeable backstraps, and the change from a 7-lug bolt to a 6-lug bolt. The first delivery of the CZ 805 occurred on 19 July 2011 with 505 guns and 20 grenade launchers. The initial order was to be completed in 2013.
