About American Made Tactical 80 Lower Receivers

AMT 80% lower receivers are manufactured right here in the USA. Every lower we make is made from 7075 T6 aircraft-grade aluminum. We want our lowers to withstand the toughest tests and to stand the tests of time, either in the field or out on the range. We constantly test and build our own AR’s using our lowers so we ensure we’re delivering a quality product to the customer, every time!

We sell Anodized and Raw options of our 80 lowers. Anodized lowers are the “classic black” option, most common on all AR builds. The raw option is un-finished, so it is the “raw” aluminum. The raw 80% allows builders to customize any type of paint they want. Want OD green? Tie-die? Pink? The raw lower is the right option for you!

We pride ourselves on our product. Part of ensuring the quality of our product is our machining accuracy. And we guarantee our machine accuracy is within one thousandth of an inch (+/- 0.001). Our lowers are also 100% MIL-SPEC. We also sell AR-15 and AR-10 billet lowers that feature an integrated trigger guard, or you can choose a forged lower to add a custom trigger guard. Our lowers also feature a broached magwell (NOT machined like our competitors).

Finally, for those customers looking to get together with a few buddies to drink a few beers and finish some lower. Or customers looking for a good family project, we offer 1, 3, 5, and 10 pack combo options. We’ve even included combo options with a jig kit so you can purchase everything you need to finish up to ten lower receivers. Our jig kits include everything you need, wall plates, four top plates, and hardware.

Our AR-15 anodized and raw upper receivers feature a reinforced wall design for added strength, dust cover port, shell deflector, forward assist (but no bolt), and are the perfect match for any of our AR-15 lower receivers.

How do you complete an 80 percent lower?

Check out a quick video on how to finish a lower with just a drill press! If you want to print out written directions, check these out.



What is an 80% Lower?

Well, the term commonly refers to an AR-15 lower receiver which has only been partially milled by the manufacturer so that it does not meet the definition of a firearm according to the Bureau of Alcohol, Tobacco, and Firearms (aka ATF). However, it should be noted that the figure 80% is not necessarily indicative of the amount of milling and drilling required to make the receiver fully functional.

Instead, when you purchase an 80% lower receiver, most of the milling work has already been done by the manufacturer. Thus, usually all that is required of the shooter is to use a jig and a router to finish milling the interior of the receiver.

What You Need to Mill an 80% lower

Because most of the milling and drilling on a lowerreceiver is done by the manufacturer, completing the process of milling and drilling the interior of the receiver is actually a relatively simple procedure that most any shooter can complete at home. Generally all a shooter needs to finish milling an 80% lower is a milling jig kit and a milling tool kit such as those offered by American Made Tactical, a vise, a router, manual mill, CNC mill, electric drill or a table top or standing drill press.



Do I need an FFL or to register my 80 Lower?

You DO NOT need an FFL to purchase an 80% lower receiver. Based on the GUN CONTROL ACT OF 1968, it is legal to build a firearm for personal use. This includes lower receivers, which are not classified as a weapon by the ATF. However, if you wish to sell, trade or give away, your AR or 80% lower receiver you ARE REQUIRED BY LAW to register and serialize that lower or weapon.


Why choose an 80% lower receiver?

There are many reasons to choose an 80% lower. A primary reason is that is allows customers to add a fully customizable element to their AR build. Sure, the builder needs to perform the finishing touches on their lower, but that allows you total customization of your AR build. In addition, finishing one gives you more intimate knowledge of the inner workings of the AR, which will help you learn how to trouble-shoot and repair any AR. Sure, not requiring an FFL is nice, but so is telling your buddies that you built your own!
