I haven’t been to the range yet. But over all they seem pretty cool. Easy to use good flip up and down. They line up nicely. Definitely will be back to give a more in-depth review once I finish my build. Delivery time was great and easy.

Thanks for sharing your feedback. We're so glad you're satisfied with your purchase. Cheers!

Quality for the price

I was going to get $200 Diamondhead sights but found these. Very sturdy lopro design. They’re on a build so I haven’t shot with them yet, but am very confident they will hold up. Went ahead and got at3’s delta ring and gas block assembly considering the quality and price of the sights.
