It is essential to verify the relevant state regulations regarding firearms models prior to commencing any project. As laws and regulations can vary significantly from one jurisdiction to another, it is crucial to ensure compliance with local authorities. For instance, as of 2025, Minnesota's laws are relatively permissive with regard to 3D firearms models, whereas other states, such as New Jersey, may have more restrictive regulations.

In addition to adhering to state regulations, it is worth noting that the use of 3D printed parts in rifle construction should not be approached as a cost-cutting measure. To ensure the durability and longevity of the weapon, it is advisable to utilize high-quality materials, such as premium filaments, and precision components, including high-end extruder nozzles. By prioritizing quality and adhering to relevant regulations, individuals can create a reliable and lasting firearm.
