JSR do;
Simmons Whitetail Classic Nightview. Great optics for £90 if you could stretch it. This will need to be parallax adjusted.
Nikko Stirling Gold Crown Airking 3 - 9 x 40 which is parallax adjustable @ £57.
Hawke Varmint 3 12 x 44 with milldots with adjustable objective @ £90 from BAR
Juat a few to think about. The Simmons will be a very good choice.
