Non-anodized Upper and 80% Lower Combo
These AR15 combo kits include both an upper receiver and an 80% lower receiver sold at a discount so you can get a set that matches from the same manufacturer. When choosing uppers and lowers from different manufacturers it is possible to have some minor fitment issues or coloring issues. Eliminate the likeliness of that with a set from the same manufacturer.
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.
