Premier 7075 T6 80% AR-15 Lower Receiver

This is hands down the highest quality, most complete 80% Lower you can buy.  Additional machining not available on other “80%” products has been accomplished and you can actually fit this unit to your Upper prior to any additional machining being accomplished.  Our 80% AR-15 Lower receivers start as high quality 7075-T6 forgings from the leading forge in the US and are fully machined to mil-spec tolerances. The operations left to be completed are as follows: fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. This is a not an FFL item. This is not a complete receiver and still requires machining to be done.  Also available in AR10/.308.

Building your AR15 Lower:

Just what does building your own mean? It boils down to finishing (home machining) your lower receiver and then assembling the remainder of your AR15 kit. In another words, attaching everything necessary to the lower in order to complete your AR.

So why on earth would you want to construct your own AR15? There can be a lot of reasons. First, it's fun! Secondly, you can save a lot of money by constructing your own. Or there is also a bunch of you that love a challenge. Maybe you are into total customization. Perhaps you seek the sense of accomplishment in knowing that you are out there on the firing range using the actual beauty that you built in your garage. Your friends probably will not believe it!

Even the BATF says that we can build our own for our personal use as long as it is not built for the purpose of selling or giving it to someone else. But... you have to be able to legally own a firearm. From everything else that we understand, the BATF does not require it to be registered either. Since we are not lawyers, you will need to do your own legal research to determine what the laws are in your local area. We can, however state, that if you live in California, your AR15 has to be California compliant in order to be legal.

We start with a raw 7075 heat treated forged lower and precision CNC machine it to military specifications. This is exactly the same forging that many of the major AR15 manufactures use.

Please do not mistake these for castings.  They are not.  They are forgings and there is a big difference between castings and forgings. In a nut shell, a casting is when aluminum is melted to the point that it can be poured into a sand mold. It is then allowed to cool and then removed from the sand. A forging is when aluminum is heated to the point of being very malleable, but not liquid.  It is forced, under pressure, into a steel mold, allowed to cool, and then removed. A forging is superior to a casting.  It retains all of its strength properties after forging.  If you start with 7075 alloy, it stays 7075 after forging.  Castings, on the other hand, loose their strength properties. A forging can be anodized whereas a casting cannot be anodized.  A casting has to be painted.

Typical Tools:

At a minimum, a floor type drill press will be necessary. You will want to insure that the chuck runs true. While you can complete it with a drill press, a mill-drill, mini mill, or an actual mill will make your job much easier. Other than your machine (with a vise), you will need some common tools such as a set of drill bits and some simple calipers.

You will also probably want a machining/drilling jig (a fixture). The jig is to help hold the lower in a vise, without damaging the surface, while working on it. If you plan to only build one AR, you can sell the jig on any one of the many AR15 web sites after completing your lower. They sell quick and often times you can recover 75%-85% of what you paid for them. There are those of you that may want to go in with a couple of friends and split the cost of the jig. We recommend that if you are using our lower to also use our AR15-JIG-C jig. On the other hand, if you are using a different companies lower, use their jig.

A note about the ATF "Letter of Determination"

The letter is what manufactures obtain from the BATF that states their product is "not a firearm". We indeed have ours. Contrary to a lot of internet forums, an ATF letter of determination does the end user no good. It only applicable to the manufacturer. Since you, the builder, can build an 80% lower into a 100% lower, the letter does you no good.
