How To

These are the How To Instructions for the Polymer80 jig and lower system. Select the instructions based on the version of the product you own. Please note, that while the videos are very informative, you will need to download the PDF Instructions First, and read them. The videos while informative, do NOT contain the sizing info that is required to properly mill out the lower receiver. We urge you to use the videos as a secondary visual guide after reading the instructions.
