In short
Act 123 of 2026 amended Act 168-2019, the Puerto Rico Weapons Act of 2020. It modified the definition of “Firearm Part” in Article 1.02(ec), which now means any component that would typically attach to a firearm and is necessary for its essential operation in the process of firing a projectile, and specifies that the essential parts covered by that definition are the slide, the barrel, the chamber and the firing mechanism. It added to Article 2.02 subsection (e)(12), providing that a current weapons licence issued by the Police of Puerto Rico is required to acquire firearm parts compatible with the firearms registered in your name, whether at a local armoury, directly abroad over the Internet, or by any other lawful means. The same article provides that at any time a person may surrender their licence to the Weapons Licence Office for cancellation, delivering their weapons to the Police or selling, donating, transferring or assigning them to another person holding a current weapons or armourer licence; and that owning a firearm is not a requirement for obtaining a weapons licence. Articles 6.05 and 6.08 were amended to expressly include firearm parts: carrying, transporting or using a firearm or firearm parts without a current licence is a felony punishable by a fixed ten-year term of imprisonment, with no right to a suspended sentence, diversion programme or any alternative to imprisonment; and having or possessing a firearm or firearm part without a licence is a felony with a fixed five-year term.
What is it?
It is a change in what counts as a “weapon” for the law’s purposes. Until now many people thought in terms of the complete firearm; Act 123-2026 puts in writing that the slide, the barrel, the chamber and the firing mechanism are firearm parts, and that acquiring them requires a current licence. Buying one of those pieces online without a licence stopped being a spare-part purchase and became a felony.
Who can do it?
Anyone in Puerto Rico who acquires, possesses, carries, transports or uses a firearm or a firearm part. To acquire parts, subsection (e)(12) requires a current weapons licence issued by the Police of Puerto Rico and that the parts be compatible with the firearms registered in your name.

Step by step
Step 1: Know the four essential parts
The Article 1.02(ec) definition is general — any component that would typically attach to a firearm and is necessary for its essential operation in the process of firing a projectile — and then it gets specific: the essential parts covered by this definition are the slide, the barrel, the chamber and the firing mechanism. Those four are the ones the law names.
Step 2: Buying online does not exempt you
Subsection (e)(12) closes that door expressly: a current weapons licence is required to acquire firearm parts compatible with the firearms registered in your name, “whether at a local armoury, directly abroad over the Internet, or by any other lawful means”. All three channels fall under the same rule.
Step 3: Possessing a part without a licence is five fixed years
Article 6.08 was written to include them: anyone who without holding a weapons licence has or possesses a firearm or firearm part commits a felony and is punished with a fixed five-year term of imprisonment. With aggravating circumstances the penalty may rise to a maximum of ten years; with mitigating ones, drop to a minimum of one year. It is aggravating that the weapon was reported stolen or illegally appropriated, or illegally imported into Puerto Rico.
Step 4: Carrying or transporting is ten, with no way out
Article 6.05 is the harshest and worth reading in full. Anyone who carries, transports or uses any firearm, or parts of a firearm, without a current licence — save as provided for shooting ranges or hunting grounds — commits a felony punished with a fixed ten-year term of imprisonment, with no right to a suspended sentence, to the benefits of any diversion programme, or to any alternative to imprisonment recognised in this jurisdiction. With aggravating circumstances it may rise to twenty years; with mitigating ones drop to five.
Step 5: You do not need to own a firearm to get the licence
The same Article 2.02 says it in subsection (j): owning a firearm is not a requirement for obtaining a weapons licence. It is the fact that helps someone who does not yet own a firearm but is going to acquire parts or plans to buy.
Step 6: If you want out, there is a written route
Subsection (i) provides that at any time a person may surrender their weapons licence to the Weapons Licence Office for cancellation, and jointly deliver their weapons to the Police, or may sell, donate, transfer or assign them to another person holding a current weapons or armourer licence.
Where to do it
The weapons licence is issued by the Police of Puerto Rico, and the Weapons Licence Office is where it is surrendered for cancellation. This Act publishes no address, portal or form.

What to do if something goes wrong
This guide describes only what Act 123-2026 changed in Act 168-2019: the definition of a firearm part, the licence requirement to acquire them, and the penalties in Articles 6.05 and 6.08. We did not read the rest of Act 168-2019, so we do not explain here how a weapons licence is obtained, exactly what the shooting-range and hunting-ground exception covers, or how aggravating and mitigating circumstances are determined. If you already have at home a piece falling within that definition and hold no licence, that is not a question a summary can answer for you: speak with a lawyer. The law publishes no cost or processing time. PRFácil does not process weapons licences or give legal advice.
Common mistakes
- Thinking a spare part is not a weapon: the law names the slide, barrel, chamber and firing mechanism as essential parts.
- Believing buying abroad online falls outside: the text expressly covers the local armoury, abroad over the Internet, and any other lawful means.
- Acquiring parts not compatible with the firearms registered in your name: the subsection makes that compatibility a condition.
- Confusing possession with carrying: possessing without a licence is five fixed years; carrying, transporting or using is ten, with no suspended sentence and no diversion.
- Not getting the licence because you do not yet own a firearm: subsection (j) expressly says owning one is not a requirement.
Frequently asked questions

Article 2.02(e)(12) requires a current weapons licence, issued by the Police of Puerto Rico, to acquire firearm parts compatible with the firearms registered in your name, whether at a local armoury, directly abroad over the Internet, or by any other lawful means. The barrel and the slide are named among the essential parts.
