• All-in-One Convenience: Every jig kit includes the specific end mill bits and drill bits required for the job. There is no guesswork and no need to source additional tooling.

 FAQ: Your Tool & Jig Questions Answered

Q1: What is an 80% jig?

A1: An 80% jig is a precision tool that holds an unfinished (80%) firearm receiver. It provides a template with guide holes and plates that show you exactly where to drill and mill to complete the receiver, turning it into a functional firearm component.

Q2: Do I need a drill press to use a jig?

A2: A drill press is highly recommended for finishing an 80% lower as it ensures your drill bits are perfectly straight, resulting in the highest precision. However, many jigs can also be used successfully with a quality hand drill and a steady hand.

Q3: Are 80% jigs reusable?

A3: Yes, our high-quality jigs are designed to be reusable for multiple builds. The hardened steel drill bushings and durable construction ensure that the jig maintains its tolerances, making it a long-term investment for any serious builder.

Q4: Where can I find instructions for my jig?

A4: Most jig manufacturers provide excellent, detailed instructions and video tutorials on their websites. For example, industry leaders like 80% Arms offer comprehensive video guides that walk you through the entire process step-by-step.

Q5: Is it legal to own an 80% jig?

A5: Yes, in the United States, it is federally legal for a law-abiding citizen to own an 80% jig. The jig itself is an unregulated tool. As always, you are responsible for knowing and complying with all specific laws in your state and city.
