1. I need a rear sight. Anyone know where to find one? I can have it fitted, but is it worth the effort?

2. It has redfield bases. Are there quick disconnect rings? Are there alternative bases? I assume the rear sight was lost when the scope was mounted. What scope? I have a few 3x9x44’s that would work well with this svelte little rifle.

I have a 3.5 to 10 leaupold on one and a 3x 9 zi on the other. both shoot trophy bonded tiped really well.

I had a trigger repaired by Steve Nelson of Corvallis, Oregon. He may be able to help or suggest someone.

Sometimes parts can be found on ebay.
There are quick disconnect rings that will fit Redfield bases but, there is no point because with the bases attached you will not be able to see the sights.
I did see a Pachmayr Lo-Swing mount on ebay about a year ago and that would let you use irons or scope.
The only other alternative bases I'm aware would have EAW make some claw mounts which are very expensive.
My advice,which is worth what you paid, is to get Buris, Leupold, or Redfield rings, mount the scope of your choice and use it.
