AR-15 Lower Receiver
This is your standard mil-spec lower receiver. We pay special attention to the core features to ensure that the function is 100% reliable. The magazine well, fire control group, front lug cutout, rear lug cut out and buffer tower are all cut in the same operation to ensure proper alignment.
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 other parts do you offer?
We also manufacture AR-15 upper receivers, AR-15 handguards and other miscellaneous components for the AR-15 platform. You can usually buy one of our build kits and save some money.
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.
