Introduction to the Polymer 80 Kit
The polymer 80 kit has gained significant traction among firearm enthusiasts looking for a customizable approach to building personal firearms. These kits allow users to create their own handguns, specifically models compatible with Glock, by assembling various parts from an 80% receiver, which is considered a non-firearm under federal law until completed. This article will explore everything you need to know about the polymer 80 kit, providing a comprehensive guide from assembly to customization.
What is a Polymer 80 Kit?
The polymer 80 kit consists of an unfinished receiver along with all the necessary components for completing a handgun, typically modeled after popular Glock designs. The term “80%” refers to the fact that the receiver isn’t fully formed and requires finishing work before it can be assembled into a functional firearm. These kits are designed to allow individuals the freedom to build their weapon according to their preferences, making them immensely popular within the DIY firearm community.
History and Evolution of Polymer Kits
The concept behind polymer receiver kits began taking shape in the early 2010s. As firearms enthusiasts sought more personalized options, the idea of completing their own 80% receivers gained traction. This evolution was marked by advancements in manufacturing techniques, allowing for durable and lightweight polymer materials that can withstand the rigors of use. Over the years, many manufacturers began producing polymer kits, leading to a wide market where consumers could choose from various configurations and price points.
Legal Considerations for Polymer 80 Kits
Understanding the legal landscape surrounding polymer 80 kits is crucial. In many jurisdictions, these kits are legal to purchase and build, provided they comply with local and federal regulations. Given that an 80% receiver is not classified as a firearm, it navigates several restrictions that apply to complete firearms. However, potential builders must stay informed about local laws, which can vary in strictness, particularly concerning registration and manufacturing regulations.
Components of the Polymer 80 Kit
Main Parts and Their Functions
A typical polymer 80 kit comprises several essential components, including:
- Lower Receiver: The core component that houses the trigger mechanism and is required for the build.
- Frame Parts Kit: Includes components like the trigger assembly, slide lock, and magazine release, which are necessary for function.
- Jig: A template that guides drilling and milling procedures, ensuring accuracy during assembly.
- Slide Assembly: The upper portion that houses the barrel and recoil mechanism, critical for firing.
- Barrel: The component through which the bullet is fired.
- Sights: Targeting aids to improve accuracy when shooting.
Tools Needed for Assembly
Building your polymer 80 kit requires some specific tools beyond just the kit components. Commonly needed tools include:
- Drill and drill bits
- Router with a finishing bit for milling the receiver
- Hand tools such as wrenches and screwdrivers
- Dremel tool for finishing tasks and adjustments
Quality vs. Cost: What to Look For
When considering polymer 80 kits, buyers often wrestle with quality versus cost. While many affordable options exist, investing in a higher-quality kit may provide greater durability and fewer complications during assembly. Look for kits that include all essential components and check reviews for customer satisfaction before making a purchase. Effective research is vital, as a poorly made kit could lead to difficulties in assembling or using the firearm.
Assembling Your Polymer 80 Kit
Step-by-Step Assembly Instructions
Assembling your polymer 80 kit can be broken down into manageable steps:
- Read the Instructions: Begin by thoroughly reading the assembly instructions that come with your kit.
- Prepare Your Workspace: Ensure you have a clean and organized work area, equipped with all necessary tools.
- Finish the Receiver: Use the appropriate tools to mill out the material as specified in the jig instructions. This typically involves drilling holes for the trigger and safety components.
- Assemble the Lower Receiver: Install parts from the frame parts kit, including the trigger, magazine release, and other components.
- Install the Slide Assembly: Attach the slide, ensuring it aligns properly with the lower receiver.
- Test the Functionality: Conduct a function check to ensure everything operates smoothly before use.
Common Mistakes to Avoid
Many first-time builders encounter pitfalls that can affect the safety and functionality of their builds. Here are some common mistakes to watch out for:
- Rushing the finishing process can lead to improper fit and function.
- Neglecting safety precautions, such as wearing goggles while drilling or milling.
- Failing to double-check alignment can result in complications during assembly.
Tips for Ensuring a Quality Build
To ensure your build is successful, follow these best practices:
- Work slowly and methodically, taking your time with each step to avoid errors.
- Consult instructional videos and resources for additional guidance.
- Engage with community forums for insights and troubleshooting tips.
Customization and Upgrades
Popular Customization Options
One of the main benefits of a polymer 80 kit is the ability to customize it to fit your preferences. Popular customization options include:
- Stippling the grip for better texture and control
- Adding extended magazine releases for quicker reloads
- Installing custom triggers to enhance the shooting experience
How Upgrades Improve Performance
Upgrading components of your polymer 80 kit can significantly affect performance. Enhanced triggers can improve accuracy, while better sights may help in improving your aiming capability. Additionally, aftermarket slide assemblies can offer improved cycling and reduced recoil, leading to a more enjoyable shooting experience.
Maintaining Your Custom Polymer 80 Kit
To keep your custom polymer 80 kit performing at its best, regular maintenance is required. This includes cleaning components after use, inspecting for wear, and lubricating moving parts. Establishing a routine maintenance schedule ensures longevity and reliability of your firearm.
