ANNEX Technical specifications for the marking of firearms and their essential components

2. For frames or receivers made from a non-metallic material of a kind specified by the Member State, the marking is applied to a metal plate that is permanently embedded in the material of the frame or receiver in such a way that:

(a)

the plate cannot be easily or readily removed; and

(b)

removing the plate would destroy a portion of the frame or receiver.

Member States may also permit the use of other techniques for marking such frames or receivers, provided that those techniques ensure an equivalent level of clarity and permanence for the marking.

In determining which non-metallic materials to specify for the purposes of this specification, Member States shall have regard to the extent to which the material may compromise the clarity and permanence of the marking.
