NOTE

Only general support level is authorized to restamp serial numbers.

If serial number is hard to read on weapon, restamp as follows: Support the receiver in the stamping area to prevent bending and distortion of the receiver.

Exercise extreme care to restamp the same serial number as original.

Restamp the serial number the same size as the original serial number.

Benelli Nova Extension

Most weapon serial numbers are 1/8 inch in height, or close enough that this size is acceptable for such restamping. In the event that a weapon has a serial number that cannot be reproduced by the use of the die sets contained in the Set D Field Maintenance Post, Camp, and Station Small Arms Shop Set, local purchase of an appropriate size die set is authorized.
