Only those changes properly promulaged in Technical Orders are acceptible. Gun plumbers are the only soldiers authorized to make small arms modifications, and they are held accountable. Funny enough, I was reading court martial transcripts on whether a Cpl had disobeyed a direct order to make some particular C7 modification or not.
The only issue with this is that Gunplumbers haven't been competition modifying lee enfields for over 30 years. Those rifles that have been modified require re-bedding many times over.
