The Lowers category consists of crucial components of firearms, particularly rifles and AR-style firearms. The term "lower" typically refers to the lower receiver, which plays a vital role in housing the trigger group, the magazine well, and serves as the foundation for attaching the stock and other parts of the gun.
When it comes to the popular AR-15 platform, the lower receiver is the serialized part of the firearm and is legally considered the actual firearm according to U.S. law. It contains the fire control group, including the trigger, hammer, and sear, which enable the firearm to be fired. Additionally, the AR-15 lower receiver houses the magazine well where the ammunition magazine is inserted.
There are different types of lowers available. A stripped lower receiver refers to a lower receiver without any internal components, making it a blank canvas for building a custom AR-15 rifle. This allows users to choose and install their preferred trigger, grip, stock, and other parts.
On the other hand, a complete lower receiver comes with all the necessary internal components, including the trigger group, buffer tube, and stock. It only requires the attachment of an upper receiver to form a fully functional AR-15 firearm.
Another essential product in this category is the lower parts kit (LPK), which includes all the necessary internal components for assembling the fire control group in an AR-15 lower receiver. Lower parts kits are commonly used when building custom AR-15 rifles.
Polymer lowers are also available, which are lower receivers made of lightweight and durable plastic instead of traditional aluminum. These lowers offer cost savings and may be preferred by some users.
It is crucial to note that the regulations and laws surrounding firearm components, including lower receivers, vary by country and region. In the United States, for example, lower receivers are subject to federal laws and regulations, including background checks and restrictions on the sale of firearms to certain individuals. Therefore, it is essential to purchase and assemble firearms, especially custom builds, in compliance with local laws and regulations.
Overall, the Lowers category offers a range of components that are vital for firearms, providing users with options to customize and build their desired AR-15 rifle or similar firearms.
