80 Lower

Looking for 80 AR-15 Lowers? This is the most commonly built and the lower that started it all. Currently all of our 80 lower offerings are from billet aluminum and have the ability to be laser engraved as well as anodized. We also offer AR-15 handguards and AR-15 Upper receivers for completing your build.


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 FFL is 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 have 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.
