(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. Each 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. Project 806 In October 2015, CZUB announced that it had introduced an improved, lighter variant of its CZ 805 BREN rifle called CZ BREN 2 (also unofficially CZ 806 BREN 2) with significantly improved ergonomics and functionality. It incorporates a number of amendments requested by the soldiers in the field, including a reduction in weight of , a re-designed cocking mechanism, a simpler cleaning routine and a new lightweight folding and adjustable foot. In January 2016 the Czech Army confirmed that they had signed contracts with CZUB for 2,600 CZ BREN 2 rifles and 800 CZ 805 G1 underbarrel grenade launchers. The decision about the purchase had been taken in late October 2015 under an urgent requirement procedure because of new security threat and the migration crisis within Europe and Egypt. Design The CZ 805 BREN utilizes a locked breech with rotating breech block driven by combustion gases tapped from the barrel and features a manual gas regulator.The CZ 805 BREN assault rifle is fitted with folding iron sights, but also includes an integral Picatinny rail on
