As long as the scope is almost new it is a good buy. You can buy them NIB for about $130.00 (CND)so you can use that as a guide to determine if it is a good buy for you. It is not that bad of a scope though.
If you present scope is the same size objective lens(40mm), you will not have to get new rings. You may not have to anyway.
If you want to, take rifle and new scope up my way your next trip. We can mount and boresight and I believe the Range is Lyons Brook is still operational.
Let me know if I can be of help.
Bring them in on a string. I love this term, if you want to be successful on calling in Elk, try not to just sound like the other caller. We all laugh at each other when we are practicing Elk calling at home or while camping. When I first started calling in Elk, I had no idea what i was doing and it's funny how many I could call in. The biggest Bull that I have called in to date was actually my first. I was making cow calls and screwing it up big time. But it's obvious I didn't screw up...
