Yah Questar used to have them, but I think you'll have to go irunguns now, be sure to get some extra magazines( 4 or 5 extra) as they don't come cheap(60 bucks each) and they are rare.
I'm looking at buying one of them for xmas as well so I might contact have to figure out how all this ironguns works.
It's one hell of a rifle! Although it looks like kangaroo poop. But I don't give a crap, i want an accurate rifle that doesn't fail to work, ever...
