Does anyone have one of these babys or have experiance with it -and yes I have done a SH search before you ask - The glass one the IOR scopes has been awesome , well with the 24 power ones I have veiwed .I know many have commented on the back up service of these tubes- has that got better with solid people like scott at Liberty selling them .Is the trackability generally sound ?They are MOA TURRETS AND 1/2 MOA RETICLE .I imagine this is a very good unit $2500 us.
