Do I Need an 80 Lower Jig to Build an AR-15?

The short answer is no, you don’t need an 80 lower jig to build an AR-15 as they make completed lowers to start with. However, the longer answer is yes, you certainly need an 80 lower jig if you are going to build an AR-15 the way it was meant to be done.

Namely, that’s crafting a weapon with your own and doing so with the freedom and liberty the 2nd Amendment intended. It is a remarkably easy and affordable process that keeps the gun grabbers out of your business and out of your pocket book.

So yes, you do in fact need an 80 lower jig to live this pew lifestyle right. Let’s break it down and talk about what that looks like for you.

The Popular 80 Percent Lower

Remarkably, the 80 percent lower is still relatively unknown to the broader pew community. However, it is growing in popularity as the word is getting out and orders are picking up with every new act of gun legislation coming down the pipes.

An 80 percent lower is simply the lower receiver of your standard AR that is 80 percent complete. Why would you want a firearm that is only 80 percent complete? The reason is that until the 80 lower is fully completed the ATF doesn’t recognize it as a firearm. As far as they are concerned the 80 lower is random hunk of metal of little use in a gunfight apart throwing it at someone.

The tactical advantages are that you can purchase these 80 percent lowers and have them shipped right to your front door without a FFL. The next step bring us to your original question. Do you need an 80 lower jig to finish the build. Absolutely, and once you see just easy these jigs are to operate you will never go back to purchasing a completed lower again.

Jigs like the 5D Tactical Router Jig Pro can knock this process out in 15 minutes and be reused over and over again. It requires very little knowledge and if you have opposable thumbs you can pull this off. There are also no short supply of videos online to walk you through the process.

Your 80 Percent Lower is Your Business

Finally, it is important to highlight that in most states across this great nation you don’t even have to report or serialize your 80 percent lower when complete. So long as you, the builder, maintain possession it is yours to do with as you please. In California, they require you to apply for a serial number once complete and, of course, hand over a little of your personal coin to the government.

Shameful, but brothers and sisters of the pew in California still have options. We just always encourage people to check their own local gun laws as we are not lawyers here and we’ve got weapons to build.

So there you have it. If you want to build a quality American made AR with fine American made products then you certainly need an 80 lower to live this life right. If you want to mind your own business and legally exercise all law abiding functions of the 2nd Amendment then the 80 percent lower is for you.

In fact, we recommend that you buy them in bulk and simply store them up for a day when you need them most. Remember, once you have the knowledge to build your own firearm this is an asset the government can never take from you.
