This is a CZ known as the BREN 2 chambered in 556NATO, model 91450.
Based on the select-fire Bren 2" this handy firearm operates via a short-stroke gas piston system with a return spring contained within the action itself. A true lightweight" the Bren 2 has an aluminum upper and a lower made of carbon fiber composite. The 'Ms' designation means that it employs a modular forend that can be swapped to different lengths or styles based on user preference/need. Its non-reciprocating charging handle stays stowed in the forward position until it is needed and is swappable from side to side. An AR-style bolt catch/release system is mirrored on both sides of the firearm" as well as a catch/release nestled into the front of the trigger guard. The magazine release and safety are also ambidextrous.
