I wish it was that simple, Brian.

The change to “Mk2” was required by the ATF. They say it’s a required correction and they will not approve it any other way.

I have had two within the past year. Copies of the original approved forms from DLO say “Sterling” and “Sterling Mk5”. The ATF required they be changed to “Mk2”.

This is specific to some DOL receivers/guns only. I had no trouble getting a mistake on Wilson corrected.
