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.

One of the best combat proven sights on the market
I've purchased these before, utilized some different brands, and I keep coming back to these sights. Really phenomenal. Tactile clicks, all steel construction, backed and made by Magpul. You really can't ask for more. I highly recommend them and Arms Unlimited sells them for a really fair price.

MBUS PROS
Absolutely the best price anywhere when I purchased. Shipping speed was decent but not extraordinary. Would’ve waited twice that for what I paid, gladly.

Once again Magpul did not disappoint. If you need a backup sight you will not be disappointed with this sight.

Sight
Works. Easy to install

Sturdy and low profile
Got these on sale along with the matching rear sight. They are sturdy and low profile when folded out of the way and are sufficient for use as iron sights in lieu of an optic.
