Good product. Excellent customer service!!
by Big Mike
I placed my first order at PA and the items were in stock and shipped very quickly. Upon arrival one of the flip-up sights did not operate properly, no fault of PA. A short call to PA resulted in a pre-paid shipping label being e-mailed to me immediately and after it was received, a new set was shipped to me very quickly again, free of charge. I will definitely shop at PA again and recommend them to my friends and co-workers.The DH-45 sights are solidly made and are a great addition to a flat top with magnified optics that cannot be co-witnessed.

Hey People, FWIW & FYI: Primary Arms ROCKS! Their Service is Incredible, I order these last Monday the 9 of Dec. and received these AWESOME 45deg. Diamondhead Sights Thursday the 12th! Texas ground shipping to VA. WOW!
<br>I believe I actually got these on Weds. the 11th LOL
<br>Okay, and again, IF Your have been on the fence about these Sights, rest assured, These are Incredible, I love them and have been looking for some kind of deal on these. Well 8 yrs. of looking around and what did I see 12-9-2019, but these Killer Sights on sale! I should buy a couple more of these LOL!
<br>Thank YOU Diamondhead & Primary Arms!
Wicked fast shipping from PA, and fantastic product. My only gripe is that I had to really lube the pivot points/trigger before they would reliably deploy every time. Since then though, they’ve been dead on.

The idea and design of these are unique. However, the first pair I ordered would not flip up or deploy the 45 degrees. I took them back and the folks at Primary Arms were more than willing to exchange them for another set. Unfortunately, that set had the same problem. They were unreliable and would only function properly about half of the time. Primary Arms was more than understanding and offered a refund.
Good as a backup

One-button to release them into position and easy to set up. Folds back down fitting flush on the top rail and the contour of the rear sight doesn't get in the way of the charging handle so you can mount it far back. They don't "lock" into position when up but have enough spring tension to return after firing, barely noticeable with a 300 BO pistol recoil. I would say the Magpul MBUS are a little bit better, but these are well worth it.
These are phenomenal flip out sights, however, they have their quirks. When you first get them I suggest oiling the springs. They come dry as hell and don't pop out like they are supposed to. Once you oil them they fire out hard! Great sights if you use a scope vs red dot.
