Choosing the Best Magpul MBUS Sights

Unless you practice on a shooting range, you know that correct aiming might make the difference between life and death. Superior sight usually means excellent aiming and accuracy. This is why Magpul has created the MBUS sight products.

These little AR-15 sights can be easily adjusted onto your common 1913 Picatinny rail, having the typical height-over-bore of your standard A2 irons. This backup Magpul sight is created by color injection molding and is the low price while still retaining the Magpul name's quality. The sight can be easily windage-adjusted with the detent knob. The sights flip open from whatever side you handle them, making them ideal for both left and right-handed operators, and can even be opened by pressing on the top.

The light polymer material adds little weight to the weapon while being durable enough to withstand the typical operational abuse. Protective wings keep the dual flip apertures shielded from any damage. There are two choices either for the rear or the front of the gun, depending on the operator's needs and the other accessories.

It is exceptionally compatible with the AR15/M16/M4 rifles and comes in four colors: dark earth, foliage green, black, and olive drab. Choose the one you like best and order your Magpul MBUS backup sight now.

What customers are saying about the Magpul MBUS

Not for use on Gasblocks

These Magpul Sights are very well designed and built back up sight. It tucks down flat and pops up when needed. I did not realize it should not be used on a gas block until after opening the package and reading the fine print. Looked at other online reviews, and some said they have the potential of melting due to the heat generated. I ended up obtaining a metal LMT sight for the front. Other than that, it seems like a great item. Just not for my set up.

Magpul BUIS are Solid Performer

Buy the Magpul MBUS set out of the gate: simple installation and reliable functioning. Front Backset is very intuitive and functions flawlessly. Well worth the price. Consider ordering off-color add ons to add a bit more style to your AR.

Great affordable Buis!

Ordered this BUIS and the mate for the front for my S&W ar10 M&P. Great sites, spot-on at 25 yards and 100 yards. The ambidextrous feature is nice. Excellent firm flips up, and spring has gentle tension to it. Sits on rail unique, feels sturdy, no play, windage adjustment stays where you set it. Will serve nicely as primary AR-15 sights will I save up for an excellent scope :) Highly recommended!

Magpul MBUS rear sight

I love the MBUS sights. I have them on three of my AR15's now. They are sturdy, durable, relatively inexpensive, and do what they are supposed to do. Just today, I went to the range to sight in an AR with both Magpul front and rear MBUS sights. Took me all of 10 shots to get these sighted in, and I was shooting around one moa at 50 yards. Not bad for a flip-up back up AR-15 sights. I highly recommend these and use them on all my builds.

Gets the Job Done

Some People will say this Magpul MBUS is inferior because it is not metal. Still, if you have another reliable primary optic, you would rarely use this backup sight anyway, and I would much rather have this backup sight than no sight. Also, I feel that there are enough polymer products out there that have shown that polymer is a durable material. These are my personal opinions.

Magpul Backup sight set

First impressions of the AR sight set are for a polymer sight is that it's SOLID. I'm very surprised and happy with how tight the fit and finish is on it. No movement between the pieces that would harm accuracy, so I believe it'll withstand the abuse and keep me shooting! The flip-up function works great and pushes down out of the way when you need it to and will fold down without having to release the catch, so you won't break it if you catch it up on something or you're doing it one-handed.

Magpul backup sights

I mounted these Magpul backup sights to a small pistol caliber carbine that wasn't going to see heavy use. The sights attach solid, flip-up with on finger push, and have positive adjustments. They hold zero and change impact consistent with adjustments. The front view comes with an adjustment tool, which is a plus. If there were one negative, it would be that they are polymer constructed, and I haven't beat these up hard enough to say if they would hold up to massive abuse. For inexpensive BUIS solutions, set about the price of a single Troy sight; they work as advertised. I would purchase again for use with range or lite duty rifles until I've beaten them up a little to see about the durability.

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.

One of the Best BUIS

This Magpul MBUS Pro Offset Sight offers the lowest profile of any BUIS I've seen when in the down position. Solid build. No additional metal or plastic-like most others. Very efficient and effective. I wish the finish were matte, but that's a minor issue. I like that it takes up very little rail space.

Best BUIS Magpul MBUS pro offset Sight

The Magpul offset sights are superb, especially when you have a scope mounted topside, but still want "iron sights." They're Magpul, so you know the quality is there. They arrived as promised and at a lower price. However, delivery was the slowest. Even after prodding the seller several times, it took over three weeks to receive sights.
