I'm planning to purchase a Benjamin Marauder and have been wondering about the scope I should get. As it is s PCP rifle I wonder if I can use a standard rifle scope - or do I need one that is specific to air rifles. I know the answer for springers, but not PCPs. I have a nice Mueller 8.5-25x44 and would love to put it on a Marauder. (Or should I look at a different rifle?)ThanksMichael (newbie)
