The CZ 807 is based from theCZ 805 BREN andCZ BREN 2. The basic characteristics of the rifle are that it is a piston operated, gas-drivenselect-fire rifle of dual calibres. The ambidextrous charging handle is easy to change sides on. It has a modular design, with an aluminium alloy upper receiver and polymer lower receiver/fire control group. The bolt is a multi-lug type riding in a bolt carrier, locking into a barrel extension. The system is balanced well, and designed to meet the most rigorous requirements.
The materials used are fire-resistant, impact-resistant, and damage-resistant. The controls are accessible from both sides. Other characteristics include folding telescopic stock and interchangeable backstraps in three sizes.
Changing calibre of CZ 807 assault rifle is simple: the barrel assembly, bolt and firing pin, and the magazine are changed out in a field-safe operation at the unit level. The trigger group of the CZ 807 has a magazine well that is for the 7.62×39mm magazines. To convert to 5.56×45mm, the only item needed for the lower (trigger group) is the magazine well insert.
