I have 2 16x, 3 6-24s and a 3-18. Most have been bought used and I am still trying to find out what can be done to fix them.
The biggest problem has been the parallax adjustment binds up when you snug up the rings....Even torqued with a fat wrench.
Had the same problem with a Vortex but they are soo much easier to deal with.
