Magpul MBUS Rear Sight - Black

Pair this with the front one and you're all set!

Great sight. Easy to install and adjust. Was tight on the picatinny rail. Good price and really fast shipping. Primary Arms is awesome.

Dunno what the fuzz is all about the roll pin coming loose etc. but We have these on all our AR's with no issues at all and even my brothers units overseas use these and most of my friends have no issues at all.

Same issue as previous reviews pins come out while firing. Happened to catch it before completely out but had to push it back in after every magazine the rest of the weekend.

Picked up a pair of these and they worked looked and installed great. Only issue I had was after exactly 90 rounds of shooting the roll pins on both the front and rear sights started working their way out. I did catch them before fully coming out will have to put something like Loctite to keep them from coming out. Have not added Loctite yet to try it again. I got these due to price but for a few bucks more I will pay the extra and get Troy for my new build.

Quality Magpul rear sight

Best price and fast shipping on a solid backup.

Very well made and esy to install

Affordable, quality, works as advertised !! I have Magpul MBUS on all 3 rifles. Primary Arms, great service !!!

I had been shopping around for a good price on these sights,and found it here at primary. They look really sharp under my scope with the low profile.

Got two. Love them. On sale for $40 bucks! Primary you rock. Put them back on sale, I need another.

Awesome product from an awesome vendor! Sights came in great condition, well-wrapped, and in great time. Very happy and will be recommending Primary Arms to friends.

Sturdy and lightweight.Quality I've come to expect from Magpul.

Its MagPul, what else can I say. Shipping was very fast. I got lucky this item was on sale and I scored big time.

Great price. Great communication. Fast shipping. What more can I say? Thank youJohn

Shipped same day.$35 per unit/sight on sale.Shipping cost was $4.58 (USPS).It just doesn't get any better than this.

Great product (and Service!).Have since bought(and received) both front and rear sights for AR-15 (300 Blackout).

Good looking sight and very well made on top of great service from Primary.

The mbus is great easy to deploy and to fold down out of optics way. Lightweight, durable, easy to site in, worth every penny.

Could not ask for better service, order filled and delivered in no time.

Lightweight and looks great.

I tried a couple of cheaper folding rear sights before getting this. The mbus is a great poly rear sight for the price. Folds flat, solid construction, typical magpul product that just plain works.

Not true iron sights but they are excellent for use as back up sights. Can't argue with the price either. Not recommended for primary sights but good for use as backup.

i really like this product locks up tight does not feel like plastic. best sight for the money. fastest shipping i have ever seen!

Received item in a timely manner and in perfect condition! I'll be doing business with P.A. in the future!
