Magpul MBUS Sights
The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. It is constructed of tough, impact resistant polymer to provide light weight and resistance to operational use.
The spring-loaded flip-up sight is easily activated from either side or by pressing the top. The spring pressure and detent keeps the sight erect and in position when deployed.
The detent knob on the rear sight easily and positively adjusts windage, and the front sight includes an elevation adjustment tool. However, most aftermarket A2 front sight adjustment tools may be used as well.
Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons. NOTE: Cannot be mounted to a railed gas block due to excess heat issues.

- Reviewed in the United States on February 5, 2014Color: Flat Dark EarthSize: Front SightVerified PurchaseOkay, I want to talk a bit about these sights. Magpul makes good stuff, and they are innovative. I have two sets of these sights mounted to a couple of my AR15's. They are lightweight, low profile, durable, economical, and very user friendly. Just click or karate chop it, and it flips up. Push it down and it locks back down. That's it! No weird cross pin style locking mechanisms, no need to push up and lock into place. When time is of the essence, just reach up with your thumb and CLICK! It's in place faster than you can blink an eye! Good sight picture front and rear. They sit really low on the rail when not used. Installation is simple. Just push it on from the end of your AR15's picatinny rail, locate your preferred mounting spot, and put the provided screw through the sight and rail and tighten it with a screwdriver. Really, these sights are idiot-proof... or are they?
Magpul should not have to put a disclaimer stating not to mount polymer sights to gas blocks. I figured it was only common sense, but after reading the interwebz and a couple of reviews from here, there are people out there who actually figured you could mount these to gas blocks, until they read the fine print... and the blamed the sights themselves. Like I said, I figured it was common sense, but then again, McDonald's was sued because a woman spilled her coffee in her lap and the cup wasn't labeled "HOT COFFEE." Go figure.
Additionally, these sights are engineered to sit on top of accessory rails (rears on AR15 flat top receivers). Of course, you can mount them to other guns, but I'm speaking to the other group of people who can't get them to sight in right because they disregarded common sense and logic and actually mounted these sights to gas blocks, and then fired the gun! Most gas blocks sight below rail height. If you want a gas block mounted sight, buy one specifically designed with the extra height (and metal) in mind. Just don't go around dogging these sights because you didn't read before you installed them.
As for durability, some people are saying that because they are plastic, they will break. Okay, well then how do you explain Glocks, FN's, XD's, M&P's and such? Oh I'm sure some have broken, but most plastic guns that are fighting in wars and being used for LE, are holding up just fine to the sort of abuses they are subjected to. My AR15 is my working gun. The MBUS sights installed on it are no exception. That AR rides in the back of pickup trucks, gets used in harsh desert conditions, fears no snow, goes up the rocky mountainsides with me, and generally sees an assortment of things that safe queens and bench rest guns would never dream of. The sights have never shot loose, never cracked, warped, disintegrated, or malfunctioned in any of the ways mentioned in some of the 1-3 star reviews. In fact, despite being on my AR15 for over a year, and accompanying me on just about every outing off pavement and away from the covered range, they still look new, aside from some dirt hiding in some of the small corners.
They also cowitness to the lower 1/3rd of an Aimpoint Comp M3 in a Larue LT150 mount.

- Reviewed in the United States on December 7, 2024Color: BlackSize: Front SightVerified PurchaseI love how durable these are! Magpul is such a good brand! I was so lucky to find these on sale for black friday! make sure you have back ups just in case your RDS goes out!
- Reviewed in the United States on July 15, 2012Color: BlackSize: Rear SightVerified PurchaseAfter building my first AR, I researched the different back up sights available out there. I could have spent a few more dollars on the fancy CNC'd pieces, but after so many favorable reviews, in addition to the price, I thought I would give it a shot.
When I got the sight, I inspected it for manufacture defects, tested operation and read the info sheet that came with it. Inspection showed no visible flash from the molding process. All edges were nicely rounded, which shows forethought into snagging on gear or clothing. Knobs are clearly marked and easily turned. The spring action is sharp, actually startled me with it's force, but I don't see it as being a problem. Mounted quickly and easily, but it's Picatinny and that's kind of the point. Manipulating it with my hands it feels solid and well built. Such is the quality that I won't be "upgrading" it to an aluminum machined sight, there's no reason other than to spend money.
The one down, and I hesitate to call it this and I won't take a star off for it, is the rear flip down aperture sight. It's a bit sticky at first, but that is easily remedied by usage. The tab to flip it up or down is kind of small and if you don't have some fingernail, difficult to flip. But really, if you're in that much of a hurry to flip from far to close and vice versa, you've probably messed up some how.
This is a backup sight for if my optics die. It folds down flat and out of the way. It seems to be rugged enough that it will stay tucked and out of the way until I really need it and work well.

2.0 out of 5 stars Missing parts
Color: BlackSize: Rear SightVerified PurchaseFirst of all... the delivery took over a month... what is acceptable due to the corona crisis.
But what I dont understand is, when I buy an iron sight for 60,00€, that the mounting screw to fix it on the picatinny rail is missing! The package looked original and unopened, but the screw and counter washer just weren't there!
Its no so much of a deal cause already got a screw and a washer outa my stash and mounted it... but for this price I expect all parts included- also because it shows on amazon with the mounting screw and also in the instructions!
It would have been nice to have all parts of this sight originally from MAGPUL as thats what I paid for!
