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.

Very good backup sight
I really like these sights. Simple. Rugged. Easy to use.

Best All Around Front Sight.
I have them on 2 of my AR15

I feel like I robbed AU
I got these at a steal, almost half off the price of the front and rear sight , both sides are top quality and are good for precision shooting with iron sights, I should know because I qualified expert with iron sites in the Marine Corps

Magpul MBUS Pro
Perfect little back ups. Dont go out and spend 200+ on iron sights when you can get the mbus pros. Great product and arms unlimited is a great site to buy them from. Im definitely looking to them first for the next major purchases i make. 10/10 for sure.

Great product/price
Recently purchased fold-up Magpul front and rear sights as backups for my AR-15. Both products were shipped quickly and arrived safely. They’re great! I know people like the regular MBUS too…but I hate the idea of plastic sights on an AR. If you’re on the fence, just do it! They fold up/down just fine, and don’t interfere with my red dot at all. Great back up sights!

Best price I found
Top quality steel sights. I own a few sets and AU had the best price by far, NIB

Wow!!
To be honest, I was skeptical. Shopping for back up iron sights and I could not believe the price. I decided to roll the dice and I am glad I did. My order arrived in just a few days and in perfect condition. I am a customer for life now. Thanks Arms Unlimited!
