In this real steel video, Gunvira tries the CZ BREN 7.62x39, comparing it to the more common 5.56 model. Whilst the rifle maintains the platform’s excellent ergonomics and fully ambidextrous controls, it requires proprietary magazines. She notes that while aftermarket adapters exist for AK or AR-style mags, she finds them unreliable and prefers sticking with the stock factory magazines for better performance.

Range testing showed the rifle to be reliable and enjoyable to shoot, with only one minor magazine-related feeding issue. Gunvira admits a personal bias toward the 7.62 round for its stopping power, though she acknowledges that the 5.56 version is softer shooting and more precise. They also tested it suppressed, noting that while it ran well, long-term suppressed use might benefit from custom gas block work or a flow-through suppressor to reduce internal wear.

Ultimately, she views the 7.62 Bren 2 as an excellent "fun" gun and a great addition to a collection. However, due to the proprietary magazine requirement, she concludes that she would still choose the 5.56 version for a high-stakes scenario. For 7.62 needs in a survival situation, she suggests sticking with the tried-and-true AK platform.
