CZ-USA CZ Bren 2 Ms 5.56 AR Pistol - Black (Model 91451)

The CZ Bren 2 Ms 5.56 AR pistol brings a modern, purpose-built design to short-barreled rifle territory. If you're after a compact 5.56 platform that borrows the ergonomics you already know from the AR-15 but with a fresh mechanical foundation, this Czech-engineered pistol delivers. The Bren 2 Ms starts from a clean-sheet design—not a military rifle chopped down, but engineered from the ground up for a lighter, more efficient package. That philosophy shows in every detail, from the aluminum receiver to the carbon fiber-reinforced polymer lower, keeping overall weight down to 5.625 lbs without sacrificing durability.

Ergonomics are where the Bren 2 Ms really shines for AR shooters making the jump. You get ambidextrous controls throughout: the manual safety, magazine release, and a dual-sided bolt catch/release that mirrors AR layout. The charging handle is non-reciprocating and stays forward until needed, then doubles as a forward assist—a smart design choice for a compact platform. The modular forend means you can tailor the front end to your build, and the 11.14-inch cold hammer-forged barrel runs standard AR-15/M16 magazines (30-round capacity). At 22.8 inches overall length with the flush rear plate, this pistol accepts AR-style buffer tube attachments for arm braces or, if you go the NFA route, a traditional stock. The adjustable folding sights keep you mission-ready out of the box.

Stippled grips provide purchase in varied conditions, and the whole platform's modularity means you can configure it for your specific role—whether that's truck gun, range beater, or the foundation of a more specialized build. Builders and AR platform veterans will find the ergonomic translation painless.

Frequently Asked Questions

Is the CZ Bren 2 Ms 5.56 AR pistol compatible with standard AR-15 magazines?

Yes. The Bren 2 Ms in 5.56 NATO uses standard AR-15/M16 magazines with a 30-round capacity, so you can use magazines you likely already have on hand.

Can I install a stock or arm brace on this pistol?

The flush rear plate comes pre-drilled for AR-style buffer tube attachment, allowing you to add an arm brace or other stabilizing device. If you plan to register as an SBR, you can install a carbine buffer tube and factory folding/adjustable stock, or replace the entire rear plate with CZ's factory stock assembly.

What makes the Bren 2 Ms lighter than other short-barreled rifles?

The design combines an aluminum receiver with a carbon fiber-reinforced polymer lower to keep weight to 5.625 lbs. The non-reciprocating charging handle and optimized components throughout contribute to the weight savings without compromising durability.

Are the controls ambidextrous for left-handed shooters?

Yes. The safety, magazine release, and bolt catch/release are all ambidextrous. The charging handle is also swappable from side to side, making the platform fully southpaw-friendly.
