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.

Need more Magpul!


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!

Amazing Sight


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!



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.

magpul mbus pro rear sight


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.

Perfect sight


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.

Great service.


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.

Great Product.


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.

Like it a lot..
