A Reliable Backup When It Matters Most

The MBUS Gen 2 is designed as a folding rear sight that mounts easily onto standard Picatinny rails. Its primary role is straightforward: step in when your primary optic fails. Whether due to battery issues, damage, or environmental conditions, this sight ensures you’re never left without a way to aim.

Quick Deployment, No Fuss

One of the standout features is its spring-loaded flip-up design. With a quick press, the sight pops into position, ready for immediate use. This fast deployment can make a critical difference when time matters.

Flexible Aiming Options

The dual-aperture system gives users flexibility:

  • A larger aperture for close-range or low-light scenarios
  • A smaller aperture for more precise, longer-distance shooting

This adaptability makes it suitable for a wide range of shooting situations.

Lightweight but Durable

Constructed from impact-resistant polymer, the MBUS Gen 2 keeps weight to a minimum without sacrificing durability. It’s tough enough for everyday use while remaining light enough to avoid adding unnecessary bulk to your setup.

Windage can be adjusted easily using a built-in knob no tools required. This makes on-the-fly corrections simple and practical, even in the field.
