The MBUS Pro 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.

Fantastic Iron sights. I didn't want the flimsy plastic ones so I went with these full metal ones and I got to say I'm pretty impressed. Usually you just leave iron sights on a rifle and forget about them until your optic battery dies in the middle of range day. Well that exact scenario happened to me so I started playing around with the mbus a bit. Damn these things are spicy. not only do you not notice them when they are down but they work absolute wonders when there flipped up. It's been several months and I shoot pretty regularly and these things haven't lost zero since the day I zeroed them. Love them, buy them, they will not fail you.
Magpul BUIS Pro's good or junk?
by John Merz
I have numerous rifles and pistols decked out in just about evrything Magpul. I purchased a Bushmaster ACR a few years ago and it came with the polymer back up sights, which at that time was pretty expensive in their own right, but I had issues with them holding a good zero, so I looked around and found that Magpul had another option of BUIS and these were metal in construction, so I picked up a set and they cost a pretty penny, back when they first came out, but with all of that being said I was very impressed at the craftsmanship of the sites. I love the was they mount onto the rail and how low the set when they in the stored position. Easy to deploy and very easy to zero them in and they seem to keep it. I would highly recommend these BUIS to anyone.
