I have a Marlin 795, same as your 7000 except iron sights and non-heavy barrel (albeit being the idiot I am, I actually broke off the rear sights trying to mount the scope from the FRONT :banghead: ), so it's actually even more like yours. Anyways, I went with the Simmons ATV (more specifically ATV4514C) scope. It's 4.5x-14x with 40mm objective, and has an A/O. Now, I'm no expert on optics, but for something like the .22lr, with some decent mounts, should work just fine. It has on mine anyways, but I've never gone to an outdoor range so I just shoot at 25yds indoors. I suggest picking up some decent mounts, because no matter how good your scope is, cheap mounts and rings will negate it. I am using some B-square 2 peice mounts with Burris signature Zee rings with those rubber thingies inside. Seems to be pretty solid. The Simmons ATV can be had for under $100 shipped from Natchez, and the rings/mounts will be another $50 or so, but not a bad deal. I hope to get out to an outdoor range some day and shoot for groups, because seriously, shooting indoors at 25yds with a bipod mounted .22lr rifle with a huge scope makes you look like an idiot. (well, maybe that's just me). Anyways, I'm sure you'll like the gun. Mine has a WAY better trigger than a 10/22 deluxe I had and sold, and feels much better in that it's lighter and to me, better looking. Enjoy!
