Magpul MBUS Pro Sight - Rear
A steel rear sight with dual apertures and tool-less windage — the MBUS Pro Rear completes a backup system you can actually rely on.
The Magpul MBUS Pro Rear Sight (MAG276) brings all-steel construction to the rear half of your iron-sight equation. The dual-aperture design flips between a large ring for fast, close work and a small aperture for precision at distance — the classic combat configuration, executed with machined precision. Windage adjusts tool-lessly with positive, audible clicks, so refining zero at the range needs nothing but your fingers.
Folded, the sight sits extraordinarily low and snag-free; deployed, it locks up without play and returns to zero shot after shot. Paired with an MBUS Pro front, you get a sighting system tough enough to serve as primary irons on a dedicated build — and dependable enough to bet on when an optic goes down.
Why shooters choose the MBUS Pro Rear
- All-steel construction — built to take what polymer cannot
- Dual apertures — fast ring up close, fine aperture at distance
- Tool-less windage adjustment — crisp, positive clicks
- Ultra-low folded profile — clean under optics, snag-free
- True return to zero — deployment after deployment
Fit & installation
