Frequently Asked Questions

Are your products legal in California?

Yes. All our products are specifically designed to comply with California state law. We are an FFL licensed dealer and every product meets California requirements.

What is a fixed magazine and why do I need one?

California law requires certain firearms to have a fixed magazine that cannot be removed without disassembling the action. Our fixed magazine housings allow you to legally own and use your MP5 clone in California without modification to the upper receiver.

What firearms are compatible with your MP5 housing?

Our trigger housing is compatible with HK SP5, HK SP5K, Zenith ZF5, Zenith ZF5K, and most MP5 pattern clones.

What material do you use?

We use Fiberon PA612-CF15 — a carbon fiber reinforced nylon that provides exceptional strength, heat resistance, and dimensional stability. This is far superior to standard PLA or PETG prints.

Do you ship to all states?

We ship within the United States. Some products may have restrictions in certain states. Please verify your local laws before purchasing.

What is your return policy?

We accept returns within 30 days for unused, uninstalled products in original condition. Please contact info@3dprints2a.com to initiate a return.

How long does shipping take?

Standard shipping is 5-7 business days. All orders ship via USPS or UPS from California.
