Magpul MBUS Pro Rear Sight


No doubt, I love me some good optics. Whether it's a Trijicon, Red Dot, or a traditional scope they all add versatility and a definite "cool factor" to your weapon. However, just one hard bump or a dead battery can spell the end to all that. The savvy shooter always has a backup plan for when the inevitable happens. Backing up your optics with the Magpul Pro rear sight will give you a way to keep on shooting, even when old Murphy shows up.

Magpul MBUS Pro Rear Sight Is Designed For The Most Demanding Operation Environments

The Magpul MBUS Pro rear sight is not some molded, polymer toy. It is a steel, professional grade, aperture rear sight that is all business. Whether you have it up or down, the Magpul Pro rear sight locks in solid. Even heavy recoil doesn't phase it, this thing is not going to move until you move it. The MBUS Pro Rear Back Up Sight from Magpul is built for the most demanding operating environments. The sight is constructed of case-hardened steel treated with a ferritic nitrocarburizing process to give it an unfaltering resistance to corrosion and other types of damage.

Certainly, the aperture style rear sight is by far the fastest, most accurate open sight available. The Magpul MBUS Pro rear sight features two sizes of apertures that need only the flip of your finger to engage. The larger aperture gives you lightning target acquisition at close range, while the smaller opening allows for premium accuracy when you stretch things out.

Backup or Primary, The Magpul Pro Rear Sight Still Got You Cover

Some folding rear sights are just too bulky to be useful. The Magpul MBUS Pro rear sight is designed for the shape of your receiver. When it's folded, you still have complete access to your charging handle. When it's engaged, you have control of your shot.

The MBUS Pro Sight can be mounted to any 1913 Picatinny or STANAG 4694 rail. This sight folds down when not in use and serves as a back up sight to the scope or red dot. You can easily adjust the windage with the knob - there is no need to carry sight adjustment tools or Allen wrenches! The sight is designed to deploy at the same height as a standard AR-15 rear sight. Both the upright and folded positions feature positive detents.
