I have a set on my T/C Black Diamond muzzleloader, holding a 4x Leupold M8. The rifle is very accurate but the scope needs to be removed every time it is fired and cleaned. At first I was worried about return to zero but not anymore. I've used the rig for several seasons with no need to readjust the zero. This design gives better repeatability than any Weaver style QR system I've seen.
