It's exactly as it should be. Serviced and greased with XG279 prior to storage by the MoD. Keep the barrel clean, screws tight and enjoy it. I always laugh at the self-proclaimed hard-core collectors that hate the post 1986 import marks. When it comes to No.4 rifles, I'll take a post '86 import marked rifle any day over a pre '68 that usually have Britishcommercial proofs and country of origin stamps. No one ever complains about those! The fact is that the rifles surplused prior to 1968 were probably culled because they failed one of the MoD gauging standards. They hung on to the good ones in war reserve stores and yours is one of those.
