MBUS PRO® FLIP-UP SIGHT SET LEFT/RIGHT ADUSTABLE FOR AR-15 Reviews & Ratings

The Magpul MBUS Pro LR Sight Set combines the rugged, all steel MBUS Pro front and MBUS Pro LR rear sights in a package that provides a cost savings. The MBUS Pro LR capitalizes on the low profile and sleek styling of the original MBUS Pro, while adding the additional feature of elevation adjustments to accurately engage targets at variable distances. Built with all steel construction, this is the sighting solution that delivers no-tool adjustments, maximum strength, corrosion resistance, and functionality in a compact package. Positive detents keep the MBUS Pro LR at standard AR sight height when deployed and so low when stowed that you will hardly notice them.

The MBUS Pro front sight offers a no-tool, elevation adjustability and excels in all 1913 Picatinny rail mounting applications, including rail-height gas blocks.

Great backup

Great quality. The adjustments are easy, but not so easy that they accidentally move. ONLY issue I see is deployment isn’t but depressing a lever like the other MBUS’. But overall fantastic

The Sleekest low profile

Much more slick than their plastic folders. Less to catch on. Durable unobtrusive.

Outstanding

Love these BUIS's!!! These are solid and tight, glad I went with these over other brands. A little tight to adjust but holding zero is more important. They match the QD sling mount perfectly.

Magpul Mbus Pro

These flip up sights give a full range of adjustments and are really tough. I now have several sets on different AR's

Feels strong and durable

Would like to rate 5star but need more testing. Bought and used for LEO rifle class but never shot out past 200 yards. I will be testing out to further ranges so I can take advantage of the BDC adjustment on rear sight. After more testing I will update review. Based on construction and low profile style, I recommend.
