Thank you all for this info!
By chance RG0311 is for sale on GB now, just an FYI, bid is $1200 now.
I don't need it-I have RG0899 which is a AE/Interarms rework, still with green hang tag.
I do have a question about these please: Do we know what regular production SNs were defaced in renumbering the RG series?
Now on GB: RG0311:
