Why Choose the Polymer80 LR-308 Lower Receiver?

As firearms enthusiasts with extensive experience in custom builds, we recommend the Polymer80 LR-308 for several compelling reasons:

• Legal DIY Project: As an 80% lower receiver, this product is not classified as a firearm until you complete the machining process, making it legal to purchase without an FFL transfer in most states
• DPMS Pattern Compatibility: Designed to work with standard DPMS pattern AR-10 parts and components
• Durable Polymer Construction: High-strength polymer material provides excellent durability while reducing overall weight
• Customization Freedom: Create exactly the rifle you want with your choice of upper receivers, barrels, triggers, and accessories

Key Features and Benefits

Build Quality and Design

The Polymer80 LR-308 features precision molding with reinforced critical areas to ensure long-term reliability.

Machining Requirements

This 80% lower receiver requires completion of the fire control group pocket and trigger pin holes. You’ll need basic machining tools like a drill press or router jig to finish the receiver. The process is straightforward for anyone with basic mechanical skills, and numerous online resources are available to guide you through completion.

Technical Specifications

The LR-308 lower is engineered to match DPMS pattern specifications, ensuring compatibility with a wide range of AR-10 components available on the market. The receiver features standard magazine well dimensions and buffer tube threads for easy assembly with aftermarket parts.
