Others may disagree but I don't see the Swaro as being any more durable than the Leupold. I own a Vortex HD LH and glass is great but adjustments are extremely mushy and I'm having doubts about how well they stay in place. If you want durability there's no way around increasing weight as it is the heavier internals that make the scope durable.

Just for set it and forget it Meopta may be a good option.Even the Burris Fullfield has been mentioned as being fairly good for a set it and forget it scope. If you want to dial adjustments in ranging SWFA or Bushnell LRHS on a budget or Nightforce if you have the funds.
