I just picked this one up but don't have it in front of me yet........ what model exactly is it? That is IF anyone can tell for sure. It was just listed as being 4" inches longer than a normal 10-22,, I'm thinking it's some variation of the 10-22 Sporter, is it a "deluxe"?. some Walmart special I've read a little about? ........man I can't wait till I receive this one,,,,,,,,, thanks guys!
