Before the Gun Control Act of 1968, Serial Numbers were used by professional gun manufacturers to create a system of organization for interchangeable parts. The use of serial numbers has also helped collectors and historians alike appraise antique firearms. However serial numbers are now legally mandatory for every purchased firearm.
And this act has taken away much of the individuality and identity that was expressed in these numbers before. However, with the rise of the 80 lower, firearms have taken back a majority of their identities in an industry that has been ridiculed in social media and politics for ages.
Here is why the AR has become so popular in today’s society.
Hopefully with our little history recap, we gave you some idea on one of the key points that perpetuates the AR’s popularity, specifically with 80 Lowers. While serial numbers are mandatory for any AR that is purchased, they are not mandatory for 80 lower builds, whose buyers have build them individually.
Since these 80 lowers do not require serial numbers, they also do not need to be registered. This takes away a lot of the hassle that comes with buying a firearm, but does give way to a new obstacle in having to build the rifle from scratch, and buying all of the parts.
It’s Your Creation
When building an AR 80 lower, you are in control. This the main reason ARs have become popular. There are virtually no regulations on these firearms, besides the ethical and the moral. And for law abiding sportsman, hunters, and DIYers, the AR 15 80 lower build is they way to go.
80 lower builds gained popularity in the firearm world primarily because they were a way to get rifles and pistols without the need for registration. Buyers can order them online and complete their 80 lowers with many different tiers of tools. But for those who have just come into the 80 lower build scene, understanding why and when an 80 lower does not need a serial can be a fuzzy area. So here we are to clear up some of the fog about serial number’s and other regulations in relation to 80 lowers.
ATF and NFA
The Bureau of Alcohol Tobacco and Firearms (ATF) is the federal power that regulates firearms. According to ATF, the part of the rifle which controls shooting, or the fire control group, must be under 80% complete to not be considered a firearm. This gives birth to the name 80% lower, as the fire control group is in the lower receiver of the AR-15.
If the receiver is under 80% complete, then it cannot be under regulation under the ATF, meaning no serial numbers are required.
However, some states, like California and New Jersey have tried to crack down on 80% lowers. The Dept. of Justice of California has issued AB 857, a law that forces legal gun owners to register any lawfully unserialized firearm with a state issued serial number.
The best way to be sure about whether your rights are protected in the state you are in, is to research and take actions with a legal attorney.
The National Firearms Act prevents unserialized firearms from containing destructive or explosive ammo. If the firearm is fully automatic, the firearm must also be serialized.
Purchasing an 80 lower is all fine and good if you intend to keep it. However, if you plan to sell your 80 lower built firearm to someone else, you could be in violation of the law. 80 lowers are strictly prohibited from being bought with intent to sell. In a court, it is usually harder to justify selling or exchanging these firearms.
However, if you do wish to sell your rifle, or any rifle for that matter, do so with an attorney, and make sure it is registered. Any firearm that is made to sell must be registered according to the law.
Hopefully this gave some insight into the nature of serialization and registration in relation to 80 lower firearms. We at Thunder Tactical understand the importance of protecting individual rights.

Completing an 80% lower receiver takes time. This labor can be heavily supplemented with the help of a jig. All it takes is a bit of know how, the right tools, and patience. And, today, our article is bringing you all the know how you need.
Here are the steps to follow in order to complete your 80% lower receiver.
The Right Tools
Having the right tools and bits is the most important factor in completing an 80% lower receiver. Better instruments produce a better quality finish. Here is a list of everything you will need to complete your 80% lower receiver:
- 80% Lower Jig (click here to view our complete list of jig kits)
- Drill press and vise
- Dremel ¼” grinding head
- ⅜” End Mill
- Drill bits 5/16”, ⅜”, 5/32”
Assemble the jig first by connecting plates A and B. Install the VA-C top plates, keeping in mind the location of the jig and the position of the trigger.
The top plate C is marked 1-¼” deep. Set the drill press accordingly, as this is the profile you will be using to make your cuts.
Using a ⅜” end mill, create a flat bottom, making sure to get out all of the “webbing” produced by the first assembly. This should open the pocket and complete that 1-¼” depth needed to complete the 80% lower receiver.
Complete the same actions with the VA-D top plate, using a ⅜” drill bit and a ⅜” end mill. Be mindful of the webbing, and use the end mill to open the pocket to the correct depth.
Switch to the 5/16” drill. Drill carefully through the fire control group at the specified hole. Watch for “drill walk” and use a file or the ¼ grinding head Dremel to create a nice finish.
Side Plates A & B
This step is pretty straightforward, but requires more technical skill to produce the best outcome. Instead of drilling all the way through on one side, make your drill holes partially on either side.
This reduces the chance of drill walk.
Complete but Not Finished
Now that you have assembled your 80% lower receiver, use the Dremel to create a nice finish. Once that is done, you have finished your 80% lower.

The AR industry has skyrocketed over the course of the past decade. Building and buying ARs has become the norm for firearm enthusiasts, no matter their level of ability.
The reason for this AR boom is the AR 80 lower parts kit. But how do you go about putting one of these invaluable kits together?
What Is an 80% Lower?
The term 80% lower refers to any AR lower receiver that is left only 80% completed. If this part, which contains the control fire group, is left unfinished like this, it is not legally considered a firearm. In reality, it is just a block of metal.
Since it is not legally classified as a firearm, the 80% lower can be delivered directly to the buyer with no regulations whatsoever. Essentially, what this means is that anyone could buy
However, this also means the buyer must have the tools to complete the lower receiver of their AR. Here are the recommended tools to complete an AR 80% lower.
What Kind of Tools?
There are a lot of ways to complete your 80% lower. With all of them though, it is important to factor in patience and careful planning.
All of these tools are dependant on their availability. Some may take a little more precision, and others may take more skill. Here is a list of the most commonly-used tools to complete
The Drill Press is designed to make cuts with precision. It is very useful because it has depth settings, making cutting holes accurately much easier.
A drill press vise will ensure no drill walk occurs, reducing the margin of error greatly.
Hand drilling is the most economical approach to completing an 80 lower parts kit. A fair amount of dexterity is required to use a hand drill. Drill walk and loss of control are more likely to occur when there are no harnesses or grips.

This is definitely the most recommended tool to have in your possession. The AR 80 lower jig includes guides on how to properly complete your receiver.
