Our 80% Lower jig kit allows someone with a milling machine or similar equipment to complete the 80% lower that is included in this kit. Vader Spade
has completed a good tutorial on how to complete the 80% lower that is included in this kit. Each piece can be replaced and if you're careful this kit can be used many times.
You can use a drill press to rough out the material in the fire control group to make your life a little easier when milling if you'd like. it isn't necessary but could give you a better result. We highly recommend following Vader Spade's recommendations.
The kit is made from 6061-T6 aluminum and has steel bushings pressed into each plate. If you have any questions or need any questions answered as you complete this there are many resources online that can be helpful or reach out to us via phone or email.
