Man, I bought a red dot a couple years ago, the battery went dead, so I go to Change it and have to use pliers to get the cap unscrewed because the threads are all jacked up. I email them and get a return authorization, send it in, they email me back after a few days and tell me they are replacing it. Sweet, new red dot. I got the new one tonight and the damn thing won’t turn on!?!? I already tried new batteries with no luck. Be on the lookout for a brand new red dot in the classies
