Understanding the AR-15 80 Percent Lower
The AR-15 80 percent lower is a component that has gained significant attention in the firearm community. It’s a part that, when completed, can form the lower receiver of an AR-15 rifle. But what exactly is it, and why is it so popular?
What is an 80 Percent Lower?
An 80 percent lower is essentially a partially completed lower receiver. It is designed to be 80 percent complete, which means that it meets the legal requirements to be classified as a firearm part rather than a firearm itself. This classification is crucial because it allows individuals to purchase and possess the lower receiver without a firearm-specific license or registration.
Legal Considerations
One of the primary reasons for the popularity of the AR-15 80 percent lower is its legal status. In many jurisdictions, owning a firearm requires a specific license or registration. However, since an 80 percent lower is not considered a firearm, it can be purchased and possessed without these requirements. This makes it an attractive option for those who want to build their own firearm without the legal hurdles associated with purchasing a completed firearm.
Building Your Own Rifle
Once you have an 80 percent lower, you can complete it by adding the necessary components, such as the fire control group, trigger, and magazine well. This process allows you to customize your rifle to your specific needs and preferences. It also gives you a sense of accomplishment, as you have built the firearm yourself.
Types of 80 Percent Lowers
There are several types of 80 percent lowers available on the market. These include aluminum, polymer, and billet receivers. Each type has its own advantages and disadvantages. For example, aluminum receivers are durable and lightweight, while polymer receivers are more affordable and easier to work with. Billet receivers, on the other hand, are the most durable and offer the best accuracy but are also the most expensive.
Completing the Lower Receiver
Completing an 80 percent lower requires some basic tools and knowledge of firearm assembly. The process typically involves the following steps:
| Step | Description |
|---|---|
| 1 | Drill and tap the magazine well |
| 2 | Install the fire control group |
| 3 | Attach the trigger and hammer |
| 4 | Install the bolt carrier group and charging handle |
| 5 | Attach the upper receiver |
Community and Support
The AR-15 80 percent lower community is quite active and supportive. There are numerous online forums and groups where you can find advice, tips, and even tutorials on how to complete your lower receiver. This community can be a great resource for those new to building their own firearms.
Conclusion
The AR-15 80 percent lower is a fascinating component that offers a unique combination of legal flexibility and customization. Whether you’re looking to build your own firearm or simply interested in the process, the 80 percent lower is a great place to start. Just remember to do your research, follow the legal requirements, and take your time to ensure a safe and successful build.
