Usage Instructions:

Secure each .308 80% lower blank in the Easy Jig® using the snap-fit clamps and rear buffer support adjusted for .308 platform. Follow sequential steps: drill pilot holes with provided bits (5/32″, 19/64″, 3/8″), then mill fire control group pocket and trigger slot using the solid carbide end mill guided by layered depth pillars. Apply cutting fluid, remove chips frequently, and verify alignment with built-in gauges. Repeat for all three lowers. Polymer80USA videos detail router settings and safe operation for flawless results.
