I'm looking at a R6600. I'm not well versed on AR's so I thought I would ask someone who is.
It seems to have a mix of features of Blue label and Green label rifles. It has the small front pin, mag release fence and bayonet lug. The serial # is SP216xxx.
Does everything sound correct? If so, what would the value be for one in 95% condition be? What date does this serial # place it at?
Thanks for the help.
