Finding the best AR-15 stripped lower receiver can feel overwhelming. With so many manufacturers and variations, choosing the right one for your build requires careful consideration. This in-depth guide will break down everything you need to know, helping you select the perfect foundation for your custom AR-15 rifle. We'll explore key features, popular brands, and factors to consider before making your purchase. Knowing what to look for in an AR-15 stripped lower will ensure a successful and safe build.
Understanding the AR-15 Stripped Lower Receiver
The lower receiver is the heart of your AR-15. It's the serialized part of the firearm, legally defining it as a regulated weapon. A stripped lower receiver is essentially the lower receiver without any parts installed. This allows builders the flexibility to customize their rifles with preferred components, giving them complete control over the final product. It’s a blank canvas ready for your personal touch. This stripped-down approach also allows for budget-conscious builds, as you can source parts individually.
Key Features of a Quality Stripped Lower
Several key characteristics distinguish high-quality stripped lowers from lesser options. These include:
- Material: Most AR-15 lowers are made from 7075-T6 aluminum, a durable and lightweight alloy. Avoid cheaper alternatives as they may compromise structural integrity.
- Manufacturing Process: Look for lowers produced using forging rather than casting. Forged lowers are generally stronger and more resistant to wear and tear.
- Finish: Popular finishes include hard-coat anodizing, which offers excellent corrosion resistance. Cerakote is another durable option providing enhanced scratch and wear protection.
- Markings: Legally, the lower must contain the manufacturer's markings, including the serial number. Inspect these markings carefully for clarity and accuracy.
- Compatibility: Ensure the lower you choose is compatible with standard AR-15 parts. Some manufacturers might offer proprietary designs that may limit your part choices.
