Rifle Scopes New kahles 6-24 as rugged and recoil proof as SB PM11 5-25x56 ?

I wouldn't worry about the Kahles. DTA has used these on their HTI platform without issues. I've have 2 March scopes on my MRAD the last year without any problems through 1500 rounds. Nightforce and other scopes mentioned should also do what you're asking without issues!
