Finding the perfect stripped lower receiver is crucial for building your AR-15. The lower receiver is the serialized part of the firearm, forming the foundation upon which your entire build rests. This guide will delve into the key factors to consider when choosing a stripped lower, highlighting top contenders and offering expert advice to help you make an informed decision.
What to Look for in a Stripped Lower Receiver
Before diving into specific brands and models, let's explore the essential characteristics of a high-quality stripped lower receiver:
1. Material and Manufacturing:
- Material: Almost all stripped lowers are made from 7075-T6 aluminum, a strong and durable alloy ideal for firearms. Look for manufacturers who specify this material.
- Manufacturing Process: Precision machining is critical. A well-made lower will have tight tolerances, ensuring proper fit and function with other components. Look for manufacturers with a reputation for quality control.
- Forgings vs. Billet: Both forged and billet lowers are popular. Forged lowers are generally more affordable and considered strong enough for most applications. Billet lowers are machined from a solid block of aluminum and are often considered to have a higher level of precision, although more expensive.
2. Features and Specifications:
- Roll Marks: These markings identify the manufacturer and model. While purely aesthetic, they contribute to the overall appearance and can indicate the manufacturer's commitment to quality.
- Finish: Anodizing is the standard finish for AR-15 lowers, providing corrosion resistance and durability. The thickness and quality of the anodizing can vary.
- Compatibility: Ensure the lower receiver is compatible with standard AR-15 parts. While most are, minor variations can sometimes occur.
3. Brand Reputation and Customer Service:
- Brand Recognition: Established manufacturers often have a track record of quality and customer service. Research brands before making a purchase. Look for manufacturers with positive reviews and a history of reliable products.
- Customer Support: Should any issues arise, having access to responsive customer support is vital. Check the manufacturer's website or online forums to gauge their responsiveness.
