The Magpul MBUS Pro Sight Set comes with the front and rear sight. The Magpul MBUS Pro Flip-Up Front Sight is a super-low profile, all steel, and highly functional back up sighting solution, and the first truly 'iron' sight from Magpul! Featuring tool free adjustment, slim design, and positive detents that keep the sight from accidentally opening or closing. This Melonite finished sight sits at standard AR height when deployed, and a tiny 0.432 at the tallest point when stowed. The Front sight is exceptionally slim for increased compatibility with lasers, lights, and IR devices for the professional users. The Magpul MBUS Pro Back-Up Front Sight is manufactured from solid steel and finished in heavy duty Melonite. Mounts on any MIL-STD-1913 Picatinny/STANAG 4694 rail including receiver-height gas blocks

  • A2 front sight post
  • Dual rear aperture
  • Windage and elevation adjustable
  • Machined from steel
  • Low profile when folded
  • Tactile detents

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.

Dead On


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?


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.
