Mabe it would sell faster under firearms accessories. Not a bad deal they usually go for around $500 or more. if Xmas wasn't right around the corner I'd probably break a finger trying to send a pm fast enough lol any way good luck with the sell.
I just sold one with that exact setup not too long ago. Try ar15.com, it should sell faster there. It just sucks because there's a new generation of those out so it's hard to move the older gens (I had an older one like yours). They do work great though, GLWS.
