Magpul MBUS PRO Offset Steel Backup Sights

These are a must for shooters who want iron sights available on a scoped rifle. It takes some practice to transition quickly from the scope, twisting 45 degrees to the left and using the irons, but once you've got the mechanics down it's easy. Gives you confidence that you can continue to engage targets if your scope becomes damaged. Very hard to twist for adjusments, but it's a bit easier with gloves on. I don't consider this a drawback as you probably won't be making sight adjustments after you've got them zeroed, and I wouldn't want them to get changed by careless handling. These steel sights are slightly heavier than I anticipated, but they are robust and I'm sure they would take a beating and stay aligned.The front sight post has two widths that can easily be changed by first twisting the sight adjustment to raise the post all the way up, then gently twisting it 90 degrees either direction. If you've got thick fingers you may need to use some needlenose pliers. Thin profile for precision/competition shooting, wider profile for easier sight acquisition during movement and transitions. Be aware that if your gas block is not the same height as your upper receiver rail, you'll either have to get a riser to compensate, or you'll have to mount the front sight on top of your handguard. Generally, the farther apart your iron sights are, the more accurate you will be. Your results may vary.The rear sight also has two peepholes. Small for precision/distance shots, and wide for easier target acquisition. The holes seem to be the same width as the standard A2 sights on an M16, but instead of rotating the sight down along a screw, which changes your windage setting (albeit by only one click) the small peep folds straight down from the front and clicks into place.If I could suggest improvements, they would be a spring-loaded deployment instead of having to open them into place manually, and a full-circle front sight post guard so that the side posts aren't mistaken for the front sight. Yes they're angled, but you're also holding the rifle at an unusual angle while shooting with these sights, so there's potiential to mistake one of the side posts as the front sight under stress. A circular guard would also reduce the potential for snagging on equipment.

I really really like these back ups, they make a hellofa lot more sense then having to take off your optic to get to your irons. I got these for my recce build and really love the look and functionality of them. id give them 4.5 stars if I could..... due to the fact that on 2 different sets and on 2 different handguards, the front sight wiggled when it was fully tightened. nothing a little shim on each side couldn't fix.... I shouldn't have had to do that and magpul needs to look into that problem because I am not the only person who has had that happen. But, if you built your rifle like I did, then you have enough mechanical skills to come up with a solution to the problem. These things kick ass and look sick too =D.....Hope this review helps =)Cheers

These are extremely well made and even melonited. They are at the perfect angle and have no 90 degree edges on them making them smooth and mostly snag free. Some people complain about the adjustments being to difficult which isn't really an issue since it is still pretty easy to adjust them and once they are zeroed you shouldn't be adjusting them much anyway. They are a bit heavy being made of steel but they couldn't be molded out of aluminium and still be this strong. The reason I gave these only 3 stars is that they flip DOWN under spring friction pressure only and it is very easy to accidentally "close" these, especially the front sight. Since they are molded it makes financial sense to use the same base for the front and rear BUIS but the critical design flaw is that there is no locking mechanism to ensure that the sights will be flipped up when you need them.

Excellent quality, beautiful fit and finish (like all Magpul stuff).They snap in place very tightly... I can't imagine any scenario where they would accidentally fold down (unless you dropped the rifle or fell on it or something, in which case you WANT them to fold down instead of breaking or bending).Adjustment screws are tight, but not ridiculously so. The average person could turn them with some effort... although I imagine fingers getting sore after 20 clicks or so.The super thin front post is REALLY nice. It feels precise, and I like it a lot better than others I have used.They are nearly invisible folded down, which I also like.Also it's worth mentioning that they line up perfectly on the barrel. This may seem obvious, but many of the cheaper ones skimp on that aspect and good luck ever getting consistency with sights that don't line up on the barrel.I was hesitant to spend this much, but I'm glad I did.

I love these offset sights. I like having a scope and i do not like having my scope mounted high to be able to see iron sights underneath. For a close combat situation, this is the perfect solution. You can use your scope or whatever you have normal, but when you need to use the backup sights, just tilt and there they are. The way these are made, they would be best mounting on the left side of the gun. Meaning, with an AR on the cheek side if you are right handed. The hash marks for sighting in are the reason. Tilting for that direction just did not feel natural for me so i mounted on the ejection side. They still work the same. You just have to remember that you turn the knob backwards from how you normally would to adjust. Also for most people once they are sighted in, they will not be changed. Just use Kentucky windage if you need to adjust.

Usually Magpul products are top notch. The sight that was delivered does Not have the sight post. WTF ....The box was beat up and had been opened.Kinda of like having a row boat with no oars.Maybe this one is their new Anti-Aircraft sight ?
