Wife's Benjamin Marauder came in with @ 12cuft tank, hoses etc.

I just can't find a 21 century air gun scope at this short search time with googling.

My favorites, so far, are Hawke AirMax/SideWinder series with the huge AO wheel.  Da-da-damn, Mil reticle/MOA adjustments?

I've shot smarter 3rd world critters from the late '70's into early '80s that were raised on less brain nutrient diets.

Engineers at Hawke Optics have caca for brains.

First, you don't need an airgun rated scope for the Marauder.  Only spring airguns need those.

Look at SWFA's site.  The rear focus fixed power SWFA SS scopes are really nice for the price.  They also carry many other brands.  You will want one that will focus to 10 meters or closer, however.

Utg SWAT 3-12x is pretty decent for money and you can pick size of AO wheel.
