Magpul MBUS Sight – Rear
If you are looking for a low-cost choice in back-up sights then Magpul’s MBUS products might be exactly what you are looking for. Ideal for increasing operator sight under stressful conditions, the MBUS sights are extremely durable and light thanks to the special polymer material they are made of. This polymer is extremely impact resistant and allows for color injection molding, which keeps the prices low.
The windage is adjustable and the AR-15 sight fits your military standard 1913 Piccatiny rail. It is especially compatible with the AR15/M16/M4 rifles. The windage can be adjusted with a special detent knob.
The rear MBUS sight comes in four different colors to choose from: foliage green, olive drab, dark earth and black. The detent and spring pressure will keep the sight erect, but it can be easily folded under pressure. The sight can be flipped open from both sides and the top, allowing both left and right handed operators to use it with ease. Protective wings prevent any damage from happening to the dual flip apertures.
The GEN 2 brings more new features to this accessory, by reducing the size and bringing both small and large apertures on the same plane.
Here are the features on the MBUS Back-up rear sight in short:
- Four color choices: olive drab, green foliage, dark earth and black.
- Detent knob adjusts windage simply and positively.
- Can be adjusted onto any Piccatiny 1913 rail or STANAG 4694.
- Protective wings to prevent damage to the dual flip apertures.
- Detent and spring pressure keep the sight erect, but can also fold under pressure to avoid damage.
- Polymer construction prevents damage from impact and use.
If you don’t want to be shooting blind you should get yourself one of these little helpers. This accessory is extremely light and handy in many situations. Get your own MBUS rear back-up sight and enjoy true Magpul quality!Specifications

Customer Ratings & Reviews
Best Backup AR-15 Sights
Works great, easy to install, and use. I can imagine this sight breaking if severely abused, but it seems pretty robust. The spring is secure, and it flips the sight up positively. I consider the Magpul MBUS sights the best backup sights you can buy without going to the aluminum varieties. If you purchase polymer sights and don't buy these, you're probably wasting your money. I have not tried to mount a scope over the top, so I can't speak to the height when folded, but the width hasn't been a problem. I'm using a medium BCM charging handle.
Magpul iron sights for ar 15
I am currently using this as my primary sight, and I love it. The peep sight is crisp and clean, and the adjustments are simple to make with positive stops to hold the windage in place. The stowage lock-up seems strong, and the deployment lever and spring combine for quick and strong engagement. Overall construction seems good and the fit is right on.
Best AR rear sight
The Magpul rear mbus works well and has the lowest profile. I feel I must have back up iron sights. Most are too high to go under most optics. These work great, and like most Magpul, are the highest of quality. Also, don't worry as much about rust having them out in harsh weather. I have gotten at least five by now, so I must like them.
Magpul mbus flip-up sights
The Magpul mbus rear sight was easy to install and looks good as well. Drops out of co-witness vision with my scope. I am delighted with these for the price point. The rear sight fits under my scope on a standard height ring. I have the same sites on my competition AR for backups as well.
Magpul MBUS rear sight
It is bought as a backup ar sight to my Aimpoint on a lightweight carbine. Minimum weight with good sight picture, especially the larger aperture. I can hit the 10-inch gong at 200-yds consistently from kneeling position. The Magpul mbus rear sight seems durable but will have to see how it holds up in the field. I'm good at breaking stuff.
Magpul Mbus Rear Sight looks sharp
I had been looking around for a reduced price on the Magpul mbus rear sights and found it here at Mountsplus. They look sharp under my scope with a low profile.
Perfect for AR Sight
The Magpul MBUS is an Excellent sight for the money. I needed a proper flip-up backup view to fit perfectly on my Bushmaster AR. I would defiantly rebuy this AR sight for future builds.
Magpul MBUS Back-Up Rear Sight - GEN 2
Good to excellent quality and easy to install. Still need to take it to the range for a test drive.
AR 15 rear back up sight.
Fast service well packaged item arrived ahead of projected delivery date.
Alright for the money
Its alright for the money, it mounts on tight, but the lever to unlock doesn't always work because the polymer deforms slightly, look up "mbus issues" for what I'm talking about. However, it does work, and shooting with it is fine
it is really a fine piece of equipment and for the price nothing can beat it, not even troy ind. back up sight. Was recommended to me.
