      Made from Billet Aluminum, these 80 lowers start from the best materials available.

      The magazine well is broached for consistent magwells from part to part.

      If looking to build something other than your standard 5.56mm AR-15 build, we have a compatibility list.

      Please Note: these lowers are not compatible with clam shell jigs.

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.

      Honestly, this is the best batch of lowers I've ever received. Nice uniformity in the aluminum, great etching on the Safe/Fire, smooth edges. Very good all around!
