Magpul MBUS Rear Sight - Flat Dark Earth

I love this sight. Whether its on a rifle with the other Magpul front sight or just paired with the standard carbine front sight/gas block this functions flawlessly. There when you need it, with a click of a button, out of sight when you don't. Great for pairing with optics. Oh, and the price is unreal for these things too!

I'm not sure why people are complaining about the roll pins coming out. Haven't seen that happen in 500 rounds. Great backup sights for the money. Got the rear for $40 and the front for $25 in FDE. Primary Arms is by far better than most retailers, especially PSA in many areas including customer service and fulfillment/shipping.

Very nice for back up sights, definitely worth the money.

This is a great back-up sight. The color matches all Magpul FDE functions flawlessly holds zero and enjoys positive firm sight adjustment. The concern of these being polymer instead of metal is one that I hear a lot but something I feel to be unfounded. If your budget keeps you from dropping over $100 per sight this is the one for you.

Rear sight went on easily and line-up perfectly through my Red Dot sight with front sight. All-in-all this product functions as advertised.

Great product, good cost and fast shipping. ......

Sights are perfect for exaclty what they are... back ups. These are not $300 iron sights, they are back ups for if optics fail. Perfect what they are

Shipping was quick and the product was correct. I definately will order again from Primary Arms and I highly recommend them.

This is my second MBUS purchase. I love these things. Low profile, lightweight, quiet. The best part is not having to change the aperture when folding the site. This thing is well thought out and truly delivers for a fraction of the price of other Back up sites. So it's plastic...BIG DEAL! It's from Magpul, so you know it's good. A lot of folks were leary going with PMAGS and those plastic feed lips. Quick question, how are those working out for you? Exactly.

Tight fit, solid product

Shipped faster than anyone else ordered from in the same week

Gen 2 Flip-Up Rear Sight Dark Earth, quality product,excellent selection, price and quick shipping.will shop again and recommend to others

These are a well made product, as one would expect from Magpul. The Gen 2 is shorter that my first gen Mbus sights and have alignment marks for your windage adjustment.

Best price I could find and quick shipping. Will definitely order again.

What more can you ask for? These Magpul sights work great and look great, plus that are affordable.

EASY to install. A no brainer. Good product.

Very affordable, quality product.... Super fast shipping!

What can I say that hasn't been said? Locks up tight, flips up super fast, positive retention when locked down, easily on of the lightest sights available, very easy to actuate the release, zeros accurately, fits under my optics and magnifiers, and last but not least: cool looking design. I only wish the switching to between cqb and long range peeps was redesigned the but I'm not marking off because I was taught to use the small peep regardless if need arises and my optic fails. As always PA performance was flawless. Another great product from a great company distributed by awesome small business!

works as advertised

This sight was great. The windage was tight which is very good. I highly recomend this product.

These are great sites for the cost. I was looking for something inexpensive for my "beater" AR and these fit the bill. I prefer MWI or PRI sight but these MBUS really are a nice unit!

Very good price, shipping time was excellent. Very pleased.

Works great and fits under the 3X magnifier very well.
