USGI, Remember how the IR replacement stocks and other Commercial made stocks have that loose U shaped fit at the recoil plate? Thats what I'm referring to. Your pic of the UN=Q fit could be tighter if locked up and squared to the plate.
It's the Same seller, some are listed on GB and at the same time on his web site. Web site says UN Q is sold. Site also says RMC/Bavarian 6,082,275 is sold, but same RMC Bavarian is still listed on GB.
His Site: JF Collectables - M1 Carbines
