AR15 80 Lowers
The AR-15 is the ultimate modular firearm: It can be legally and easily built as a rifle or pistol chambered in 5.56 NATO, .223, or 300 Blackout with the simple swap of a barrel. The market is flooded with thousands of build kits, optics, BCGs, pistol grips, buttstocks, handguards, barrels, and accessories. Most black rifle owners pride themselves on their custom creations. After all, buying a "retail rifle" at the gun store usually means paying an unnecessary premium and you're going to swap out parts either way.
Why not build your AR truly from scratch? With an AR-15 80% lower, that's exactly what you can do.
What is an 80% Lower Receiver?
Not known to all firearm owners or builders, the ATF and Gun Control Act of 1968 both say it's legal to privately gunsmith a rifle or handgun from scratch in the comfort of your own home. No FFL license or paperwork is required. As long as you can legally own a gun, you can build one. That's where the AR-15's 80% lower comes in: Like the rest of the rifle/pistol, this unfinished lower receiver makes it easy to fabricate your own stripped lower using some hand tools and a jig.
Since the 80% receiver (officially classified as a "receiver blank" by the ATF) isn't fabricated or functional, it's not considered a firearm. That means it ships directly to you without any special paperwork, background check, FFL transfer, or other requirements.
How Hard is It to Fabricate?
Fabricating your receiver blank and making it a functional stripped lower is easy. The AR-15 jig you'll use to cut and drill the receiver includes easy-to-follow instructions and the required drill bits and end mill bits. Most first-timers can get the job done in around two hours. Fabrication is complete and your receiver's ready for a lower parts kit, buffer, and upper once you've completed four steps:
- Drill the hammer pin hole
- Drill the trigger pin hole
- Drill the safety pin hole
- Cut the main cavity for the safety, trigger, and hammer
All you need to complete these four steps is a basic drill press, a stable work bench, a vise, and some lubricating oil. The provided end mills are center-cut, allowing you to make vertical plunge cuts with a drill press. This negates the need for a more expensive router or milling machine.
Benefits of an 80% Lower vs. a "Retail" AR-15 Receiver
With the extra tools and time, you'd think a store-bought receiver might be the better choice. But consider this: With an 80% lower, you don't need to pay an FFL transfer fee, a background check fee, any state fees, and no extra taxes. You don't need to fill out bureaucratic paperwork, you don't need to wait 10 days to pick up your receiver, and once you own a jig and the tools, you can machine lower after lower for any AR build!
