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.
Note: This item is brand new, taken off a factory Colt or FN rifle, and packaged in VCI (blue) anti corrosion plastic bag or in milspec white bag. No different that what you get in a retail package, but full disclosure, and priced a few dollars less.
Charlie's loves Troy and Knighs Armament. We think this is every bit as good. The MBUS Pro is designed and built 20 years after thost iconic front and rear sights. If we were branding for Magpul, we might call this "Magpul Elite." It is really good, solid, reliable, easy to use and lays low when not in use.
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 sight 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
Made in the USA.
Mounts on any MIL-STD-1913 Picatinny/STANAG 4694 rail including receiver-height gas blocks.
