## Description

The next evolution in Magpul's MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths and value of their original MBUS and MBUS Pro Sights in a feature-packed back-up sight system. Significantly reduced in size from the MBUS, it sits at just 0.44" high when folded and 1.15" at its widest point. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable. Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The MBUS 3 Rear Sight sits at standard height when deployed and includes a rapid-select aperture system.

Review: They work. - Exactly what ive come to expect from magpul. Nice low profile back up iron sights for a good price and they are basically spot on from the factory. I put two set on two different rifles and neither one required any adjustments whatsoever.
Review: Love These Sights – Reliable and Easy to Install - I absolutely love these Magpul MBUS 3 front and rear sights! They fit perfectly on my Picatinny rail and feel solid once mounted. Installation was quick and simple, and the low-profile design is excellent for keeping things streamlined. The polymer construction is lightweight yet durable, and the flip-up action is smooth and secure. Perfect as backup sights or even primary for certain builds. Highly recommend for anyone looking for quality and reliability at a great price.

## Questions & Answers

**Q: how many slots does this use?**
A: What do you mean slots, it takes one leg on the pic rail to mount. and is about 3 legs long.

**Q: Will this s co witness with vortex spitfire 2 red dot sight?**
A: I think you mean Vortex strike fire II. I have this on the 1/3 cantilever mount. It co witnesses with my MBUS pro’s. All Magpul sights should be same height over pic rail.

**Q: Can I swap the front post for a standard a2 front post?**
A: I wouldn’t buy the set if you want to use the A2 front sight.  You can buy just the rear sight only which would save you money.

**Q: How is co-witness with this set?**
A: Depends on if our optics height.
