Rear Sight Problem ?

[USGI]

Charlie, I just spent the last hour or more looking at those same (5) listings on GB. Studying the IP, the M1A1 with the "extra band mark" on the stock, and the 6.6 Inland - trying to remember if it should be a "hand stamped." the metal on the Inland looks "scary" in the photos. Question on the recoil plate fits - how can they put the gun together without the reciever locked-in with the plate? Or, is that how they end up with all the chipped out slots for the recoil plates? - Bob
