[Night-Stalker]

So, noob question here. I bought the gun about 9 years ago, never used it, shot it a few times in my backyard then put it in my closet where its been in the box it came in for all that time.

There's a slight rotation of the barrel which I assume is from handling it, or picking it up from the barrel end. I assume that can be tightened easily.

Gun comes with he standard one mag and rod. I have a battery for it too but at this point I doubt its of any use.

What would a fair price be for this? I'm not sure exactly due to its age.

If I'm posting in the wrong forum I do apologize.

Thanks,
