This product was created for compatibility with Mil-Spec 80% AR-15 lower receivers no matter whether they are polymer or metal. The Universal Jig is designed with a super rigid long-fiber nylon composite, which will allow the customer to utilize the jig up to 3 times. This low-cost jig is the perfect alternative to the expensive and more complicated metal jigs, especially if you're just planning on building a few AR-15 lowers. The jig provides a stable platform for milling, and therefore encompasses the entire AR-15 lower receiver. Other competing jigs are more difficult to secure the lower in the vise, and can damage the lower receiver while milling.
