  • Our AR15 80 lowers include an upper tensioning set screw hole to tighten the upper and lower fit to your liking.
  • 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.
  • Set screw not included, available for purchase
  • Our no bull return policy backs you in case you aren't happy or just change your mind.

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 Cerro 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. If you want all three, check out our 80% Build kits.

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.

      AR Lowers

      Look great! I had to go on line to figure out what the included plastic tipped Allen screws were for but they're great, too! The eliminate the play between the upper & lower. They were a very nice surprise added to the box!

      Helluva good deal

      Its getting close to the deadline. Figured I would purchase a few extra lowers to have on hand. I chose the raw to ceracote at a later time. Well machined. No blemishes. They snap onto my uppers with no issues. We only have a few days before changes take effect so get em while you can.

      Overall great product only criticism the hole for the safety detent is not drilled big enough all the way through and has to be reamed out for proper operation.
