My M1A is serialed 0619XX, so I assume it is Jan or Feb 1991 production. It has a TRW bolt and a 10-62 H&R barrel and the rest of the parts GI. TE is negative 1. My question is this; is the barrel chrome lined? Thanks, Bruce.

Yes all GI barrels were chrome lined.
You should be able to study the chrome at the muzzle and chamber ends. Specially at the muzzle...it should be evident.
