About
What it is, and why it matters
The CZ Bren 2 is a select-fire assault rifle chambered in 5.56x45mm NATO, produced by Česká zbrojovka Uherský Brod since 2015. This Czech-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 30-round magazine capacity, this assault rifle offers generous firepower for duty use and home defense. The 14.0-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. At 3000g (105.8 oz), this is a substantial firearm whose weight contributes to reduced felt recoil and enhanced stability during precision shooting. The aluminum alloy frame achieves a notable weight reduction compared to all-steel construction while maintaining the structural rigidity required for safe, reliable operation. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.
The Bren 2 emerged from a rare admission of design flaws in a modern military rifle. When Czech soldiers criticized the original Bren 805, CZ didn't defend their design-they went back to the drawing board and created a rifle so improved that even competing nations like Hungary adopted it over their traditional AK platform.
The Bren 2 was developed after Czech soldiers complained about the weight and ergonomics of the original CZ 805 Bren. The redesign resulted in a lighter, more balanced rifle with improved handling characteristics. The three-stage gas regulator ensures reliable operation in adverse conditions. The rifle uses STANAG-compatible magazines for 5.56mm and standard AK magazines for 7.62x39mm. A battle rifle variant (Bren 2 BR) chambered in 7.62x51mm NATO with a 16" barrel is also available. Ukraine has licensed local production of the Bren 2. The civilian semi-automatic version is marketed as the Bren 2 Ms.
