The AR15 80 Lower is a crucial part of any AR15 build. An AR15 80% lower receiver provides you, the builder, with an opportunity to build a custom AR-15 rifle or pistol from the ground up, including by fabricating the firearm component (the stripped lower receiver) itself.
When it comes to building an AR-15, only the stripped lower receiver is considered the firearm. This is the component you normally purchase from an FFL. An AR-15 80% lower is an unfinished stripped lower receiver that is not considered a firearm under federal law. That means you can purchase it directly, with no FFL, serial number, or paperwork required*. You must then fabricate your unfinished lower to make it a functional firearm. Then you can then assemble your lower into a finished AR-15 by purchasing an upper assembly and lower parts kit, or grab a complete AR build kit.
*State laws vary. Some states require all firearms to be serialized. Some states have banned 80% lowers.
There are countless AR-15 parts manufacturers on the market today. Like any stripped lower receiver, a fabricated AR-15 80% lower is compatible with all standard AR parts. They work with standard AR-15 uppers, lower parts kits, buffers and buffer tubes, and all other AR parts and accessories.
