Purpose of a 80% lower?

[MacGyver]

Man, there are a lot of reasons to do an 80% lower.  I built a 10/22 from the ground up with an 80% receiver a couple of years ago and it was well worthwhile for several reasons:

 

1. The quality of a billet receiver is far better than the cast factory model (this applies to the 10/22 not necessarily the AR15 platform)

2. You gain an intricate appreciation for what it takes to put together a quality firearm - and I'd argue you learn a lot more about the platform than you would on a regular build

3. Because a clean receiver with no markings is nice looking

4. Because you can

5. Because sometimes things are worth doing by hand - at least once

 

I recognize that all of the above reasons may not mean anything to someone who looks at the value proposition of doing one themselves and then thinks, "a stripped lower costs about the same."  We're in a time where our economy has become dependent upon people thinking that everything is disposable and anything can be had at the click of a mouse with free 2-day shipping as a bonus. 

 

Some things are just worth doing.

Since the 80 lower is an un-serialized receiver blank, it can not accept a trigger, hammer, or safety, therefore it is unfinished firearm that's not operable and can not be made to operate without additional fabrication and because of this ATF does not recognize this as a firearm. 

Here is the actual purpose of 80 lower receivers. 

There are few good advantages that come with building your rifle with an 80% lower instead of just buying a stripped lower for a custom build. 

It doesn't require to be serialized. In-fact federal law clearly states that a firearm made for personal use doesn't require any serialization. Although the state laws might vary and some states might do require serialization for blank receivers before fabrication.

The FFL isn't required to purchase one unlike stripped receivers or firearms. You eliminate going through a gun DEALER or FFL. Since 80 lowers are not FIREARMS, you can actually ship them at your door steps. 

There is no BACKGROUND CHECK needed to buy a 80% lower. 

And they are more affordable in-terms of pricing and privacy of what you have ownership of which is your business only. So that's pretty much it.
