The only writing on the scope is IR 3-12 x 40 ARF, no manufacturers name or anything else.
I have 2 spare scopes that aren't on any rifles, one is a Hawke Fastmount 3-12 x 40 and the other is a Hawke Eclipse 3-9x 50 AOIR. The Eclipse is probably too long and too strong a magnification for the Pard so I'll maybe try the ARF one first and if it doesn't work well I'll try the Fastmount. If that doesn't work then I'll look at the other scopes on my other rifles to see if any of them will do.
