I bought a cheapo Center Point reflex sight and have used it on a .357 levergun, a Beretta CX4 Storm and it now sets on top of an AR-15. I've have it for about 2 years now and it has worked great on all of the rifles (so far). It is the only CP product I have bought, and for $30 bucks, I couldn't be happier with it.

Not the same luck with a BSA scope I bought a year or two back though, it sux. My scopes are Leupold, Redfield, Vortex and Swift mostly, with a few old Tasco and Bushnell's in the mix. I would not be afraid to try a CP scope.
