3D printed firearms refer to guns and gun components that are manufactured using 3D printing technology. This process involves creating items by layering materials, typically plastic or metal, based on digital models. There are several key aspects to consider regarding 3D printed firearms: 1. **Design and Files**: Firearms can be designed using computer-aided design (CAD) software, and the designs are often shared as downloadable files online.

Chamber pressure refers to the pressure of the gases within a combustion chamber, such as that found in internal combustion engines, firearms, or gas turbines, at a given point in time. This pressure is a crucial parameter that affects the performance and efficiency of the engine or device. In internal combustion engines, for example, chamber pressure impacts the power output, fuel efficiency, and emissions.

A takedown gun is a type of firearm designed to be easily disassembled into smaller components for easier transport and storage. Typically found in rifles and shotguns, the takedown feature allows the firearm to be separated into two or more parts, such as the barrel and receiver, without the need for tools.

In firearms, the term "mainspring" refers to a key component of a firing mechanism, particularly in older firearms and some modern designs. The mainspring is a coil spring responsible for providing the necessary force to operate the action of the firearm. Its primary function is to drive the hammer or striker forward when the trigger is pulled, ultimately striking the firing pin or directly igniting the cartridge's primer.

The "boyfriend loophole" refers to a gap in domestic violence laws in the United States that allows certain individuals with a history of domestic violence to legally purchase firearms. Specifically, the loophole exists because current federal law prohibits gun purchases for individuals who have been convicted of domestic violence offenses or are subject to restraining orders, but these prohibitions typically only apply to individuals who are married to, live with, or share a child with their victims.

A firearm rack is a storage solution designed to hold and organize firearms securely. These racks can be used for rifles, shotguns, and handguns, and they come in various designs and sizes to accommodate different types of firearms. Firearm racks can be made from various materials, including wood, metal, or plastic, and they may be intended for use in homes, gun shops, shooting ranges, or law enforcement facilities.

A "stray bullet" refers to a bullet that is fired but does not hit its intended target. Instead, it can end up hitting an unintended person, object, or location. Stray bullets are often a result of gunfire in urban areas, celebratory gunfire during events, or incidents involving reckless or careless shooting. They can pose significant risks to public safety, causing injuries or fatalities even when the shooter did not aim at anyone.

A **Forced Reset Trigger (FRT)** is a type of trigger mechanism used in various contexts, most commonly in firearms and some electronic devices. In the context of firearms, particularly semi-automatic or automatic firearms, a Forced Reset Trigger is designed to reset the trigger mechanism automatically after the weapon is fired, allowing the shooter to continue firing with a lighter, reactive trigger pull. This can lead to an experience that resembles fully automatic firing, even though the weapon may still be classified as semi-automatic.

Gun control refers to the laws, policies, and regulations that govern the manufacture, sale, transfer, possession, and use of firearms.

A crystallite is a small, single crystal or a region within a polycrystalline material where the atoms are arranged in a highly ordered structure, resembling a perfect crystal. Crystallites are typically found in materials that are made up of many such small crystals, resulting in a polycrystalline structure. Each crystallite can vary in size and orientation, contributing to the overall properties of the material.

A laser sight is a device attached to a firearm that projects a laser beam onto the target, helping the shooter align the firearm with the intended point of aim. It provides visual guidance and allows for faster target acquisition and improved accuracy, especially in low-light conditions. Laser sights come in different configurations, including: 1. **Rail-Mounted Lasers**: These are attached to the accessory rail of the firearm, typically under the barrel or on the side.
