Well, after doing some shooting this weekend and going into a "fun" 3D tourney on Sunday, I have to say I'm very impressed with these sights. Fine diameter pins, little blockage of target with pin arms, and not over-powering brightness.

The only thing that I would suggest to anyone purchasing these sights is to make sure the wingnuts on the entire sight block (which, by the way are convenient for adjustments without tools) are as tight as possible with your fingers... then they won't move on you, like the did to me on Sunday, halfway through the shoot!!! AND make sure once sighted in, everything is marked so that if it does move, you can quickly restore it to original position.

By the way, this sight accepts the "Nitro Stix" glow sticks. Great little accessory, not too bright but just enough....
