Finding the best AR-15 stripped upper receiver can feel overwhelming with the sheer number of options available. This comprehensive guide will help you navigate the market, understanding the key features, materials, and factors to consider before making your purchase. Whether you're a seasoned AR builder or a first-time enthusiast, we'll equip you with the knowledge to choose the perfect upper receiver for your build.
Understanding AR-15 Stripped Upper Receivers
The upper receiver is a crucial component of any AR-15 rifle, housing the bolt carrier group, charging handle, and barrel. A "stripped" upper receiver means it comes without any components – no barrel, bolt carrier group, charging handle, forward assist, or dust cover. This allows for maximum customization, letting you choose parts that perfectly match your needs and budget.
Key Features to Consider
Several key factors influence the quality and performance of an AR-15 stripped upper receiver:
1. Material:
- 7075-T6 Aluminum: This is the industry standard, offering a robust balance of strength, lightweight design, and corrosion resistance. Most high-quality stripped uppers are made from this material. Look for this specification explicitly stated by the manufacturer.
- Forged vs. Billet: Forged uppers are created from a single block of aluminum, pressed into shape. Billet uppers are machined from a solid block of aluminum, offering potentially higher precision but often at a higher cost. Both are durable and reliable options.
2. Manufacturing Quality:
- Finish: A durable finish is essential for protecting the receiver from wear and corrosion. Anodizing is a common and effective finish. Look for a consistent, even finish free from blemishes.
- Tight Tolerances: Precise manufacturing ensures all parts fit together smoothly and securely. Loose tolerances can lead to issues with functionality and reliability. Reputable manufacturers prioritize tight tolerances.
- Markings: Legitimate manufacturers usually include markings indicating their name, model number, and possibly the material used. Missing or unclear markings should raise suspicion.
3. Features:
- Forward Assist: While not always included on stripped uppers, the forward assist helps chamber a round if the bolt doesn't fully go into battery.
- Ejection Port Cover: Protects the ejection port from debris and helps maintain a clean firearm.
- Dust Cover: Similar to the ejection port cover, this protects the internal components of the upper receiver.
Top Considerations for Choosing Your Upper Receiver
Beyond the technical specifications, here are crucial factors to influence your decision:
- Budget: Prices vary significantly depending on the material, manufacturer, and features. Set a realistic budget before you begin your search.
- Intended Use: The intended use of your AR-15 (e.g., target shooting, hunting, home defense) can influence your choice of upper receiver.
- Reputation of the Manufacturer: Choose a reputable manufacturer known for producing high-quality, reliable components. Research reviews and seek recommendations from experienced AR builders.
Finding the Best AR-15 Stripped Upper Receiver for You
The "best" AR-15 stripped upper receiver depends on your individual needs and preferences. Prioritize quality materials, tight tolerances, and a reputable manufacturer to ensure reliability and longevity. Thoroughly research different brands and read reviews before making your purchase. Investing in a high-quality upper receiver is crucial for building a reliable and accurate AR-15. Remember to always follow all local, state, and federal laws regarding firearm ownership and usage.
