I have two hunting MLer's that I have put scopes on. First is my H&R Sidekick:
This is a 2.5x scope from Tasco and is just right in my Virginia woods.
For any long shooting areas I have a Knight Vision with a Leupold Ultimate Slam 3-9x 40mm:
Both scopes were designed for ML shooting. I have had good quality scopes on MLer's that had broke and I had to send back to the factory for repair. I don't do that anymore.
