Frequently Asked Questions
What tools do I need that aren’t included?
You will need a drill press or router, a vise to secure the jig, and safety equipment like eye protection. Common hand tools like wrenches and allen keys are also required for assembly after machining.
Is the lower receiver serialized?
No. This is an 80% lower receiver, which is an unfinished component. It does not have a serial number and is not considered a firearm under federal law until you complete the machining process. Always check your local and state laws regarding unfinished receivers.
What is your return policy for this item?
We offer a 30-day return policy for unaltered, unused items in original packaging. Due to the nature of 80% products, any item that has been drilled, milled, or otherwise altered cannot be returned for safety and legal reasons.
