There are a lot of misconceptions about 80 lower AR-15 Parts. And if you have done any research, or planned on building one for yourself, chances are you have heard them yourself. While this may not answer all the questions you have, it will denote the main misconceptions that come up in the 80 Lower world.
The main misconception revolving around 80 lowers is that they are illegal, or a loophole in the law. This is simply not true as the laws are clearly stated within the ATF as well as the Gun Control Act of 1968. As long as the fire control group is not complete on a rifle, it cannot be considered functional.
It is however illegal to sell an 80 lower built rifle, or build with intent to sell. They will need to be registered, though this is not always a 100% guarantee. What is certain is that build an 80 lower rifle is completely legal.
A lot of builders and DIYers are hesitant to begin their first build. This is due to the perceived difficulty of building the rifle. Little do they know, there are many guides out there, along with a community of people willing to help troubleshoot problems, and answer questions. AR15 Parts are relatively easy, especially when you have Thunder Tactical, who is dedicated to giving helpful tips and high quality parts to consumers of all skill levels.
Som may argue that store bought AR-15s are more durable than 80 lower built AR-15s. This is simply untrue. When building your own AR, the quality control is up to you the consumer. Researching the best types of materials is where most of the effort must be used.
In most cases, store bought ARs use the same materials as 80 lower built rifles. Otherwise the materials are all up to the builders desires.
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.
There are many parts and tools needed to complete an 80% lower. Although there can be some variation in the type of tools you need, there is one that is of utmost importance to have the best result every time: the 80% lower jig. But what is this tool, and how can it help you get the best results?
Think of the 80% lower jig as a template tool. Its main purpose is to guide the builder, giving proper measurements of drill bit holes, and where exactly the milling needs to be done.
They come in many different varieties. Try to stick with multi-use jigs, as they provide longer usability. If a piece has outlived its usefulness, then you can order another of that same plate singularly. There are sticker variations which are meant to stick on to your incomplete receiver.
Jig variations that hook on and give more clear also have features that prevent builders from milling too deep, reducing the risk of permanent damage to the receiver itself. When it comes to milling out the mass of metal on the inside of the receiver, jigs are the best at decreasing the risk of damage.
The 80% lower jig is the most vital part of an AR build. And the best 80% lower jig kits come from Thunder Tactical! Our jigs come in 7075 T-6 airplane aluminum and are guaranteed long lasting results.

AR building has come a long way. There are many different strategies to complete an 80 AR lower receiver. For beginners, knowing the right tools to use, what materials are best, and the plan to complete makes all the difference. Here are 3 very important things to consider when completing an AR 80 Receiver.
The Right Tools
A jig and a jig kit are the most necessary tools to complete an AR 80 receiver. They help with holding the receiver in place, and display the exact points to drill in order to create the control fire group. Many tools can be used to complete it from hand drills to CNC machines. Make sure you have the correct bits for your receiver.
Types of Material
There are two types of materials that AR 80 receivers can be made from. Different materials affect build strategy and longevity so it is very important to know what you want and why. AR’s are made in aluminum and polymer. Aluminum ARs can come billet, forged, or cast. Here are the specs on each type of lower.
Billet – These are the most common and middle tier receivers. A billet lower has a moderate difficulty on build time and are not overly expensive. It is also very easy to find a reliable manufacturer .
Forged – Forged lowers are the most high-end receivers out there. They are mil-spec, meaning these are “military grade” receivers. They are relatively more difficult to complete, requiring much more technical skill, and are heavier. They do provide a more unique with a more rustic tone. Manufacturers of forged lowers are also very reliable.
Cast – Choosing cast is not the most popular option, due to the process of casting itself. If the mold can produce air holes, they can form into pressure cracks that damage the integrity of the rifle. It is also important to say that cast lowers are not always bad, but the reliability of the manufacturers is far and few between.
Polymer – These are the easiest to complete because of the softness of the material. However, its softness also means that it is not the best AR 80 receiver to buy and keep as a long term investment.
AR 80 receiver completion is typically done in phases. This helps keep parts, bits, and tasks organized. The 3 basic phases are milling, installation, and assembly. Keep every tool, bit, and part organized to ensure a smooth build.
