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.
