This kit from Polymer80 gives you the core components you need to finish a lower receiver at home, without the need for a serialized part. The gray finish is clean, low-profile, and works well with almost any upper receiver color.

Overview

The p80 g150 ar-15 80% receiver kit – gray is designed for builders who want control over their firearm’s foundation. The kit includes an 80% lower receiver made from reinforced polymer, a jig, drill bits, and all necessary small parts to complete the lower. Because the receiver is not yet a firearm under federal law, it can be shipped directly to your door. You will need to complete the machining steps yourself, which involves drilling and routing the fire control pocket. The gray color is molded into the polymer, so it resists scratching and wear better than painted finishes.

• Includes 80% lower receiver, universal jig, end mill, and drill bits
• Reinforced polymer construction with integral trigger guard
• Compatible with standard mil-spec AR-15 upper receivers and parts kits

Shipping & FFL

Because the p80 g150 ar-15 80% receiver kit – gray is classified as an unfinished receiver, it does not require transfer through a Federal Firearms License (FFL) holder. It can be shipped directly to your residence or business. However, you must verify that possession of 80% receivers is legal in your state and local jurisdiction. Some states and municipalities have restrictions or require serialization once the receiver is completed. By purchasing this kit, you acknowledge that it is your responsibility to comply with all applicable laws. No FFL transfer is needed for this item at the time of sale.
