Building your own AR-15 can be a rewarding experience, allowing for customization and a deeper understanding of your firearm. Choosing the right stripped upper receiver is a crucial first step, as it forms the foundation of your build. This guide will explore the key factors to consider when selecting a stripped upper receiver and highlight some of the top contenders on the market. We’ll delve into materials, features, and considerations to help you make an informed decision.
Understanding the Importance of the Stripped Upper Receiver
The stripped upper receiver is the core component of your AR-15 upper assembly. It houses the bolt carrier group, barrel, and other essential parts. Choosing a high-quality stripped upper receiver is paramount for ensuring the reliability, accuracy, and longevity of your firearm. A poorly made receiver can lead to malfunctions, safety issues, and ultimately, a frustrating build experience.
Key Factors to Consider When Choosing a Stripped Upper Receiver
Several crucial aspects influence the quality and performance of an AR-15 stripped upper receiver:
1. Material:
The most common material for AR-15 upper receivers is 7075-T6 aluminum. This aluminum alloy offers a robust balance of strength and lightweight design. Look for manufacturers who specify this material, as it ensures durability and resistance to wear and tear. Avoid receivers made from inferior materials, as they may compromise the integrity of your firearm.
2. Manufacturing Process:
The manufacturing process significantly affects the receiver's quality. Forged receivers are generally preferred over billet receivers due to their superior strength and durability. Forging involves shaping the metal under high pressure, resulting in a stronger, more consistent structure. While billet receivers are machined from a solid block of aluminum, they can be susceptible to stress fractures under heavy use.
3. Finish:
The finish of your stripped upper receiver influences its resistance to corrosion and wear. Common finishes include:
- Anodizing: This process creates a hard, durable coating that protects the aluminum from corrosion and wear. Type III hard anodizing is the most common and durable option.
- Cerakote: A ceramic-based coating that offers superior abrasion and corrosion resistance compared to anodizing. It's also available in a wider range of colors.
4. Markings and Specifications:
Ensure your stripped upper receiver is properly marked with the manufacturer's logo and any relevant serial numbers, as required by law. Verify that it meets the necessary Mil-Spec dimensions to ensure proper fit and function with other AR-15 components.
5. Budget:
Stripped upper receivers range in price, depending on the material, finish, and manufacturer. While it's tempting to opt for the cheapest option, remember that investing in a high-quality receiver is an investment in the overall reliability and safety of your firearm.
Top Manufacturers of Stripped Upper Receivers (General Mention - No Specific Product Endorsement):
Several reputable manufacturers produce high-quality stripped upper receivers. Research and compare various brands based on your budget and specific needs before making a purchase. Look for manufacturers with a strong reputation and positive customer reviews. Remember to always prioritize quality and safety.
Conclusion: Building with Confidence
Selecting the right stripped upper receiver is a pivotal decision in your AR-15 build. By carefully considering the factors discussed above and researching reputable manufacturers, you can ensure a reliable and durable foundation for your custom firearm. Remember to always prioritize safety and follow all applicable laws and regulations when building or modifying firearms.
