Need a set of rings to fit picatinney rail??

Just need a set of workable rings, trying to stay on the cheap side. Will a set of Weaver or Redfield or Leupold 2 piece rings work? Will not be shooting any trophy animals or high dollar competition matches.

Will you need to move the scope to another rifle throughout the year, or will the scope life on that rifle always?

One rifle. Scope is old 1" Redfield 2 3/4 power with a post reticle.

Warne mounts are great. DNZ's are my favorite one piece mounts.

Yes, they will work just fine.

Yes, those will work.

Just be aware of the height that you need. Nothing worse than having to "hunt" for a sight picture.
