Received one sight that was not working correctly. Contacted them and they immediately sent out a replacement. I gave 5 stars for the much appreciated service, as for the sights they feel solid and the one that works is nice. Will have to update once I receive the replacement and get them shooting.
I ordered these sights for my new AR to give it a finished look because it didn't come with any sights at all. They fit perfectly and work great! Here's a pic of my DPMS Sportical!
Easy to place on rales. This is the second purchase. One on a AR 15, and one on a AR style .308. Has two peep sights of different sizes that flip up & down within the sight frame.. Sights fold down so your able to use a red dot or scope. Unless you shoot every day & go thru thousands of rounds regularly. These will work for a long time.
Needed a front sight to fit a lower gas block. Both of these sights work just perfect together. Easy install, easy adjust. Tough.
