Deactivated (weapon)
A deactivated weapon is formally one that has been rendered incapable of expelling or launching a shot, bullet, missile, or other projectile by action of explosive; which cannot be readily restored to do so; and which has been certified and marked as deactivated by a competent state authority.
Deactivation requires that all pressure-bearing components of a weapon be permanently altered in such a way so as to render the weapon unusable. This includes modifications to the barrel, bolt, cylinder, slide, firing pin, and receiver of the frame.International Small Arms Control Standards (ISACS) 01.20 Glossary of terms, definitions and abbreviations, http://www.smallarmsstandards.org/.
