I noted at the gunshow today several vendors with Okay 30rd mags in bulk but in very good condition.  These appear new and have green followers.  The question I have is that they have a light green or almost lime green color.  They are far from the color of my other USGI mags.  The price is $20.00 or $15.00 for 2 or more.  Any ideas or comments?  The color sure looks suspicious.
