80 percent lowers

80-lower.Com is my go to website for everything for my builds. Can you please explain which modulus arms jig you are referring to? I have one that I bought about 5 years or so ago, maybe longer. What makes this one better than the new one out from what you know since I have not used one yet, nor converted any lowers? I actually was thinking about getting the new one that modulus has out, 5d tactical.

Also can get new frontier armory style ar9 & ar45 80% lowers now. I have one of each laying around waiting to be built over the winter. Another cool looking billet 80% maker is juggernaut tactical. Since I’m already milling/routing I like to add pdq levers to mine. Not cheap compared to standard bolt catch but gives you ambi bolt catch/release.

We encourage each and every builder to perform their own research about the state and federal laws that apply to them. It is your responsibility to understand the law and we encourage you to consult with an attorney or your local atf representative. Officially called a “receiver blank” by the bureau of alcohol, tobacco, and firearms , an 80% lower is an unfinished receiver that isn’t considered a firearm. Cutting and drilling the lower at home with hand tools turns it into a ready-to-build firearm by legal definition. Whether it’s an ar lower,308 80 Percent Lower Receiver ar lower, 1911 frame, or a polymer 80% pistol frame, thousands of shooters have built reliable and accurate rifles and pistols with our units. The ar-stoner 80% lower receiver is forged from 7075-t6 aluminum for a precise high quality build. 80% lower receivers are available in-the-white or anodized black and require machining by the user to complete.

It’s not out of the ordinary to see stripped lower receivers from quality brands for as little as $50. However, they can certainly cost a lot more – especially for receivers that have unique looks. Some options, usually stripped lowers, are cost-effective enough to purchase multiple at a time and begin a few new builds or have them as spares in the future. With a guarantee like that, it’s easy to see why more people are giving polymer lowers a chance to prove themselves. Polymer receivers, like the ones from tennessee arms, can be the subject of some controversy on internet forum boards or out on the shooting range.

The gun control act of 1968 says building a firearm for personal use without a license or paperwork is perfectly legal. The atf also says 80% lowers are legal and aren’t considered firearms.

Juggernaut and plain ol' 80% arms lowers are top notch but most any 80% aluminum lower will be fine. Thank you for your reply, I look forward to see a real comparison between jigs and lowers from more than one supplier. The team got really excited at how different the easy jig 2 was compared to the old drill press jigs we've used.

Of course, you don’t have to worry about that with polymer as you’re just exposing more of the same polymer as you’re doing your machining. Usually, that means you’re just going to have the thing re-anodized or paint anyway so I’d just go with the cheaper option of the raw aluminum.
