RE: Is this sight worth the $.
I am very skeptical about them. I dont like not being able to crank down on my sight to make sure its good and tight. Its a good idea, and if they would make it all from metal, including the brittle pins they use, its would be a good one to have. There are just too many thing going wrong with them right now.
I too recommend the Copper John Dead Nuts sights. I just bought one this summer and must say its the best sight I ever owned. All metal, big, strong allen screws to snug down, and metal, fiber optic pins. Not to mention a nice, round pin guard to center your peep on. I highly recommend them.
