Who It’s For

This Polymer80 AR15 80% Receiver with Jig Kit is intended for individuals who wish to manufacture their own firearm for personal use. It is suitable for hobbyists, DIY builders, and those who prefer to assemble their rifles from the ground up. Because the receiver is not a firearm until machined, it can be shipped directly to your door without going through a Federal Firearms License (FFL) dealer. However, you must be legally eligible to possess a firearm in your jurisdiction. This kit is not for those seeking a drop-in solution; it requires mechanical aptitude, patience, and the proper tools to complete.

• Builders who want a lightweight lower receiver option
• Individuals who prefer to avoid FFL transfer fees for the initial purchase
• Anyone looking to customize their AR-15 build from the ground up
