Ratings & Reviews
Magpul MBUS Pro
by Eric -
Love the metal construction and small footprint. Definitely a great BUS
Please rate the product first
People, when writing a review on a product please give your 2 cents on the product quality and use, I know Primary Arms has great customer service and shipping but don’t give a review on a product and state Wow I got it in 2 days. Give an honest summary of the product and then close with how great the company’s service is. A lot of us use the reviews so see if the product is good or bad, we can’t gauge that by havin 75% of the total reviews just stating how fast it got to you. Thank you all
Primary Arms seems to have the quickest shipping of any vendor I have purchased from. Ordered the front & rear set of the Magpul Pro sights on 3-29-16 arrived in my mailbox 3-31-16. You have certainly earned my repeat business!! You guys are great!
Excellent Customer Sevice!!

Ordered my item online and it was shipped that same day!!! Like always, Primary Arms delivers excellent customer service and fast shipping.
The perfect rear iron sight.
by DAVE O.
A perfect fit, very durable, accurate. Folds flush onto a flattop receiver. All-metal construction.Has a flip down precision aperture to reveal a larger close range/lower light/quick aquisition aperture with the same zero.Also very easy to adjust for both windage and height (I use it for a quick ranging zero). Very positive detents, will not move unless you move them.
Great product and service. Slow shipping.

The product shipped out of primary arms fast. Unfortunately the post office screwed up delivery and I received my product 2 days late.
