Magpul MBUS Pro Rear Sight - Black

This sight costs a bit more than the standard polymer MBUS, but is everything the polymer sights are not! Rock solid mounting, slim metal design DOSE NOT impede access to the charging handle...Seriously, buy quality and cry once! You won't find this one in your box of spares.

Love the magpul pro sights. Much better than the polymer ones.

Purchased both the front and rear. I wanted something I never needed to upgrade and that could serve as my main optic until I saved enough coin for a Trijicon ACOG. Before buying I was torn between these and the Troy battle sights. I am happy I went with these. I like to tinker and add new parts often which means taking the gun apart and sighting in often. The ability to adjust the sights without tools sold me for this reason. I know half the time I would forget to bring tools to the range which could mean complete wastes of trips. The dial to adjust is firm so you cannot accidentally bump it and adjust it. Holds zero perfect and has very tight engagement when flipping up and down. All my holes either touch or go through one another at 50 yards. That's precise enough for me. Also built like a tank. PA as always was perfect.

Was expecting a much larger unit but it fits very well on my upper when folded it sits low on rail when up it is solid and cowitnesses with my YHM flip up gas block front site. Primary Arms service is top notch great prices and shipping is fast unfortunately our Fed Ex driver can't read and delivered my package to the neighbors house and they are gone on vacation.

These are great sights with my front sight at whichever elevation it was at (a2 gasblock) it came dialed at 25 yards. Move my target back to 50 and made a few windage and elevation adjustments and I was good. The windage knob is stiff and not easy to move which is a good thing it feels like it will require very deliberate movement to adjust.

Works perfect. clicks up or down with very firm detents, stays in place, small footprint, very well made steel construction. does not wiggle around, highly recommended.

love the sight perfectly as described mailing was awesome fast and on time! highly recommended

I got this because I didn't want to put a plastic sight on this current build and I'm glad I didn't. This is an excellent sight. Very slim, low profile and very sturdy. The aperture is crisply machined. The overall piece was a bit stiff to operate but after playing with in a little bit, it is perfect now. Highly recommend.

This sight is very high quality, sturdy,and reliable. I couldn't be happier with this purchase.

For years I hated the old Mbus plastic Magpul flip-up sights, bulky and plastic cheap. These are low profile and aluminum with negligible weight.

Just as I ststed.. I like this sight a lot..

The sight is as expected, very durable feeling. This sight does fit under a magnifier in an absolute co-witness setup. I use an Eotech 512 and a PA 3x long eye relief. All three fit on the receiver without issue.

No issues here.

First of Primary Arms has amazing service and crazy fast shipping, Love em. As for the rear sight it is everything you could ask for at an extremely reasonable price. Solid construction, positive up and down positions and windage has nice positive clicks. Stop looking and wishing and just BUY!

I looked all over for these sights. I called and talk with a knowledgable individual who took extra time to ensure they had two of each set. He answered all my questions. I ordered them on line and had them in 3 days. Great service. I will come here first in the future.

The rear sight I got was one of the early defective sights, from the first run. It sat a little crooked on the rail, however Magpul replaced it already for free.

Could not wait for the new MBUS Magpul sights. Totally stoked to see that PA had both the front and rear sights in stock. Ordered them, standard shipping and literally they were in my mailbox 3 days later. Great job PA! You will have my business again!

Will continue to shop here!

Compared to the regular Magpul rear flip up sight, the PRO version seems to have a much better front sight picture. For a few extra $ this is a better sight. It does have to be flipped up manually (no spring & lever) but I won't go back to the regular version.

Great steel rear flip-up Magpul sight with no snags working charging handle. Delivered quick from Primary Arms. The price was a jump from the previous Magpul mbus sight I have but there was a jump in construction as well. Top notch quality all around.

Awesome, but pricey, but awesome.

It is a very nice back up sight. Very easy to adjust. It is slim and out of the way when I don't need it. Thanks.
