Historical profile
Developed from 2006 under the Czech Army's individual weapon modernization program and adopted in 2011 as Útočná puška CZ 805 BREN A1.
Modular platform with aluminum upper receiver, interchangeable barrels (277 / 360 / 407 mm) and ambidextrous selector; criticized for its high weight (~3.8 kg).
The 805's shortcomings led to the development of the CZ BREN 2 (2015), about 700 g lighter, which gradually replaced it as the standard service weapon.
