The MBUS (Magpul® Back-Up Sight) Pro is a corrosion-resistant all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that’s even smaller than its size.
The dual aperture, windage adjustable rear and no-tool, elevation adjustable front excel in all 1913 Picatinny rail mounting applications and mount to your WK180C easily. Positive detents keep the MBUS Pro Front and Rear at standard sight height when deployed, and so low when they are stowed that you’ll never notice them until they’re needed. Narrow width front sight is compatible with most IR aiming laser and light installations for the professional user.
MAG275 and MAG276 are not sold individually, but only as a pair.
