I had that and I could never get it tight enough to keep it set. I bought a Extreme Archery Raptor sight with tool-less adjustment. so much better!
G5 Opix 5 pin. I haven't had to use it at over 30 yards while hunting but the 50 and 60 yard pins are a lot of fun when at the range. I shoot a 2008 Ross Cardiac 33 and with those sights on her she dots some real sweet groups all the way out to 60 yards.
I have the same sight as you. Mine is 4 pin, all .010 When I was looking at a sights, the other one I really liked was the cheap extreme sight, the RT900 I think. I just put out a set of criteria. 4 .010 pins lost camo metal housing and the light shining down onto the fibers, not the into the sight frame The vipers look pretty awesome. If i get bored enough this summer i may play with one of those.
I had an older cobra easy slide single pin, the inside ring and pin fell out the other weekend in the woods so I went out and bought an HHA single pin, so far I really like it, the fiber wrap around the outside makes the pin really bright without a light
