MBUS Pro Sights

The MBUS Pro (Magpul Back-Up Sight) is a corrosion resistant all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk. The steel case is hardened and finished with Melonite QPQ for extreme resistance to wear and corrosion.

MBUS Pro sights will mount on any MIL-STD-1913 Picatinny/STANAG 4694 rail, including rail-height gas blocks. The rear sight has dual apertures and features a low-profile knob for easy no-tool windage adjustments, and the front sight features a no-tool elevation adjustment knob.

Positive detents keep the MBUS Pro Front and Rear at standard sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed. The narrow overall width of the front sight is compatible with most IR aiming laser and light installations for the professional user.

The MBUS Pro Front Sight features a steel, rectangular sight post selectable between Match and Standard widths. Match width is 0.40" for increased precision, while Standard width is 0.60" for maximum stability.

The real deal-not for air soft
5 Stars
The real deal-not for air soft
I was so hesitant with the purchase that I tried canceling it after I ordered, seconds after my husband noticed it’s under “air soft” category! Amazon moves so fast with their one day shipping that they literally tried shipping it the next morning at 5AM! Gates are closed at that time to our complex & they tried again a few hours later so I thought to check it out. Nowhere on the box or instructions does it say they are for air soft! I compared the item to the legit Magpul site & there are the exact ones on their site! I thought it was a steal for $80 o when Magpul advertised $114 on their site. Won’t be returning the rear site unfortunately Amazon was able to cancel the front site post so I cannot speak about its authenticity.

5.0 out of 5 stars Accurate, Slim, Convienent,
Reviewed in the United States on October 12, 2015
Hi guys, after using these Iron sights extensively, I would like to give my input to help others.

I have this paired with the MBUS Pro LR Adjustable Rear Sight. These iron sights are some of the most accurate sights I've ever used. The front sight post on this sight is slightly slimmer than a regular A2 front sight post that comes on the standard AR. I feel that I can shoot more accurately with a slimmer front sight post because it doesn't cover the target as much. This is just my opinion though, others may not feel the same way, just because it's slimmer doesn't mean it's more accurate, it's more of a user preference. The best part about these sights, there's no need for any tools to adjust them which is just plain awesome and It has positive, sturdy adjustments.

The build is very quality, EXTREMELY low profile and has a nice protective finish. It doesn't require any buttons to deploy or put back down which makes it much more simple and faster to use, but it's not as secure as other sights that have a locking system that keeps them deployed.

With all that being said I chose these as my primary back-up sights and currently run these on my rifle over my troy battlesights which I really love. I just feel more accurate with these sights and they're very low profile and slim. I'll end this review with a few photos to give you guys an idea of the sight picture and how they look like on a rifle.

That's it for my review, I'd appreciate it if you guys let me know if it helped you out. Thanks.
