Save your money - Diamondhead Polymer Diamond Integrated Sigting System With Nitbrite Top Mounted Deployable Iron Sight

I want to give this a lower rating but i do like the sight picture. The rear sight that i got does not fit my milspec rails. I had to basically pound it on and now it wont come off. It being so tight it does not flip up right either. It gets half way then i need to push it the rest of the way. I dont want to damage it so i am going to leave it where it is. Front sight is fine. Save your money and get the metal version of these. I wish i did.
