The MBUS Pro (Magpul Back-Up Sight) 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,
including rail-height gas blocks. Positive detents keep the MBUS PRO
Front and Rear at standard AR sight height when deployed, and so low
when they are stowed that you'll never notice them until they're needed.
Narrow width Front is compatible with most IR aiming laser and light
installations for the professional user.
All steel construction
Case hardened and finished with Melonite QPQ for extreme resistance to wear and corrosion
Mounts on any MIL-STD-1913 Picatinny/STANAG 4694 rail including receiver-height gas blocks
Elevation adjustment knob no tools required
Positive detents in both the up and down positions as well as on the elevation knob
