I'd love to get a Terrapin X but it's just not in the budget. I've thought about the Sig Kilo 2200 or Nikon Black 4k, but I just heard about this option having fantastic glass and ranging successfully to 3000 yards ++. Is this a better option than the Kilo 2200 or Black 4k? It gets points with me for the tripod mount which the others don't have.
