Hi JohnDoe,
Your query is covered by the IRR of RA 10591:
Renewal of Licenses and Registration
All types of licenses to own and possess a firearm shall be renewed every two (2) years within six (6) months before the birthdate of the licensee. Failure to renew the license on or before the birthdate shall cause the revocation of the license and of the registration of the firearm/s under said license.
The registration of the firearm shall be renewed every four (4) years within six (6) months before its expiration. Failure to renew the registration of the firearm on or before the expiration of its registration shall cause the revocation of the registration of the firearm and the same shall be subject to revocation proceedings.
Failure to renew a license or registration within the period stated above on two (2) occasions shall cause the holder of the firearm to be perpetually disqualified from applying for firearm license. In meritorious cases, however, the Chief PNP, as recommended by the Chief, FEO, may allow the further enjoyment of the privilege under these rules subject to certain conditions which may be deemed appropriate to impose.
It shall be the obligation of the licensee thereof to surrender the said firearm to the police office or station with jurisdiction over the place where he/she resides within fifteen (15) days. Failure to surrender within such period shall cause the filing of appropriate charges for violation of the law.
