I suggest that you check out this model of Hawke scopes for your air rifle. https://us.hawkeoptics.com/airmax-30...40-amx-ir.html
I have the larger 44 mm on my HW95L as this model was not yet available when I purchased mine. This is an excellent scope with no problems after 7K to 8K shots.
I also recommend 2 piece medium rings and these are excellent. https://us.hawkeoptics.com/tactical-...mm-medium.html
