Magpul MBUS Pro Flip Rear Sight is a corrosion-resistant all-steel backup sighting solution that delivers maximum functionality and strength with minimum bulk. Positive detents keep the MBUS Pro sight at standard AR sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed.
