Magpul
The Magpul MBUS Pro Offset Flip-Up Rear Sight is a steel backup iron sight designed to keep your AR-15 ready for anything. Mounted at a 45-degree angle on the side of your rifle, this offset rear sight lets you rotate your gun and aim through it if your primary optic gets damaged or fails—or when a threat closes in fast and magnification becomes a liability. It's the insurance policy that actually works, built from all-steel construction with proven durability that Magpul shooters have trusted for years.
Offset rear sights serve a specific tactical role: they sit out of the way of your scope or red dot, then snap into action when you need them. The MBUS Pro platform delivers the reliability you need for that moment. Mounting is straightforward on any AR-15 or rifle equipped with an M1913 Picatinny rail. The sight locks down with a positive detent when deployed, so it won't shift on you mid-string. Windage adjustment requires no tools, making it fast to dial in at the range. The dual rear apertures give you options depending on your light and distance, and the low-profile design keeps the sight compact so it doesn't snag on your gear or interfere with your primary optic setup.
Built in the USA from Melonited steel, this sight is made to handle the hard use that field and tactical work demand. Corrosion resistance means it'll stand up to the elements whether you're hunting in wet weather or running drills at the range. The offset configuration is right-hand side, designed to work seamlessly with most common AR-15 setups.

Yes. It mounts on any AR-15 or rifle with an M1913 Picatinny rail. The 45-degree offset positioning keeps it clear of your magnified optic when stowed, so there's no interference with your primary sight picture.
That's exactly what it's built for. When you rotate your rifle 45 degrees, the offset rear sight comes into alignment and gives you a fully functional iron sight solution. The dual apertures and tool-less windage adjustment let you get back in the fight quickly.
No. The windage adjustment is tool-less, so you can zero it at the range or make field adjustments without carrying extra gear.
The Melonited steel construction offers extreme resistance to wear and corrosion, so the sight will handle hard use and weathering without degrading.
