My new postage stamp IHC is a bit of an enigma. For starters, it's a Service Grade CMP rifle COA dated 6-16-2014 and Armorer's tag dated 11-16-12. It apparently went thru SA at some point in time as the receiver leg has electro penned scribble on it. The stock was stamped on Wednesday, 18 Aug 1954 and the barrel is an LMR dated 8 54. All the parts are IHC except the SA bolt and the Gas Cyl Lock Screw. I thought about changing the two parts but then decided to just leave it as is. It looks like SA reparked it? Whatever, it's a beautiful rifle nonetheless with at ME of 1 and a TE of 3+.
