Here's another EFR 3-9x33 A/O on a loooong CZ 2500, a rather unusual rifle with 29" barrel. This one has a Timney trigger, is really accurate and quiet with that long tube.

I have the same scope on my 452 (which also has a Timney:).......best scope I've had on a rimfire.
Went old school with a Leupold 4X Rimfire and those ugly old Weaver rings on my 10/22.....it seemed like the thing to do on a FS rifle. It works fine for plinking which is all I use this rifle for.
