Shipping & FFL

This product ships directly to your residential or business address within the United States.

However, you must be at least 18 years of age to purchase, and we reserve the right to verify age and legal eligibility. Important FFL Disclaimer: Once you complete the receiver by machining the fire control pocket and trigger pin holes, the finished lower receiver is legally considered a firearm. Federal law requires that any completed firearm manufactured for personal use must not be sold or transferred to another individual. You are solely responsible for complying with all applicable federal, state, and local laws regarding the manufacture and possession of firearms. By ordering this polymer80 ar15 80% receiver w/ jig kit, you acknowledge and accept these responsibilities.
