Hey, check out the SWFA Super Sniper. SWFA SS Riflescope
I think that link will get you there. Plenty of vertical adjustment, mildot, tall turrets with perfect tracking, rear focus and 30mm tube. It won a navy contract and hundreds have been sent to Iraq and Afghanistan. As far as recoil, it will handle 50BMG! Water proof guaranteed to 15 feet deep and an operating range of -50 to 130 degrees. Only SWFA is licensed to sell them, so the absence of middle men bring the price of the scope down to $300.00 When it is tested, it is always tested against Vari-X IV and NF scopes. Not as good but damn close at just about a 900 bones less! Check out the various sniper forums. They have all done reviews of it.
