Nice set of rings and rail has served me well. We are moving away from imaging so these are no longer needed. We changed the screws from the original steel ones to nylon. The original steel screws had small vinyl tip covers which, when they wear out, allow the screws to scratch your scope. The nylon works great.
The rings are $119 from Ken, will sell these for $80 + shipping to your location. Checks, Cashiers, Money Order, or Paypal. If personal check, I will ship them when the check clears.
