80% Lower Jig Kit

This is a package deal including an 80% Lower and jig packaged together as a single unit. This allows you to save a bit of money when purchasing the kit from Tactical Machining. We also sell the replacement parts individually in case you damage your jig in milling.

Tactical Machining has been manufacturing firearms parts and accessories since 2008. Tactical Machining was the original manufacturer of 80% lowers for the AR platform. No FFLs are required to ship this item as it is not considered a firearm.

What is an 80% Lower?

If you're looking for more information on what an 80% lower is we built a good guide explaining the 80% lower builds. We also encourage you to ask questions through the "ask question" button on our website. One of our experts will get back with you regarding an answer.

What about the rest of your build?

We offer support through your build once you have completed the 80% lower itself. If you're in need of gas port sizes, we list those. We also provide information on basic troubleshooting on your AR-15 as well.
