Trying to help my Dad set up a rifle he just traded for. I have and shoot numerous Savage rifles but have no experience with this one. It is a Savage Model 116 that appears to have come from Cabelas. Looks a lot like a Weather Warrior except it has a heavy, fluted barrell. Hinged floor plate. Accu-trigger. Very smooth action for what its worth! I think from looking around its a Long Range Hunter but have never seen one and just wanted to check. My main question is that it came with bases already attached. Are these worth keeping? Should I replace them for him? Are they Weaver or Picatinny? I have single piece EGW bases on my other Savages and I am going to try and set this rifle up so he can shoot out to 500 (maybe more . Have a Sightron III 6.5-24x50 to put on it for him. So new base and rings or just new rings? Any other experiences you can share would be great, thanks in adavance for any help!
