The quality of the set I received was horrible. Wanted these to work out because it was exactly what I wanted but the set I got was unusable. Spoke with a cobratec rep and told me some were very good and some have quality issues. I ended up returning them.

I love these sights even though they dont flip up automatically but the button is solid and keeps the sights up or down. I got these for a 308 build that did not come with sights. They are easy to read and you can adjust windage and elevation. The rear sight even has the small and large sight hole.

Top Value. Solid metal construction with very good design. Yes, these do not have a spring and do not “pop up”. I have found that function to be unnecessary over engineering. This design is simple and functional. What more could you ask for at such a great price.

Nailed it! i have been waiting for these to come back in stock for a few weeks finally got to put them on my rig. fit and finish is great, they lock up nice and tight, elevation is adjusted with m4 sight tool, love the diamond shaped peep, price is very good.. only down side is the button to deploy the sights is a little tought at first but with a drop of oil and a few up down deployments its butter smooth so i wont give it 4 stars since it was easy to "break in"

These are not in anyway, shape, or form acceptable. They don't pop up. You must move them up manually. Secondly..once up....there is 1/16 inch of sloppy wobble in them. Not cool. I was so dissapointed. I really thought that they would be an acceptable replacement for Black diamonds.... But they are not even close. manual flip up with spring loaded retention is normal.. Slop is not normal please log in and start a return request

I received these sites last week and I put them on my A.R. 15 the quality of them are really good and they were great I would highly recommend them

what a deal on these sights! look great super quality construction, holds zero on my 308 after 50 rounds at the range. absolute high precision consistency from a flip up sight! Great product guys!

They are well built and can take abuse. 

Fit right on rails and great sights.

No wobble. Folds down with ease. Sleek look.

Great sight picture no spring tension that pops them up quick that causes more wear tear.

It has a strong lock up too. No side to side play
