I can't believe this thing is still here. I know why you're selling it(and I can't blame you) but the price on what you're asking for this thing is awesome.
Just found the invoice for the ProSX upper. Built in Sept 2003 at a cost of $2300.00(that is upper only, no frame, scope, scope mount, trigger work and parts, mag well, or tuned and numbered mags)
Damn that thing is a beauty. Wish I could afford it. I was scraping the money together for the Limited gun you had posted but by the time I had it together it was sold. Oh well. Bump it up
