Description
Please note that the handguard will not come installed onto the receiver. You will have to simply install that yourself. It is really simple and part of the "builder" experience!
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, lower parts kit, and buffer assembly with pistol brace. This kit does not include a lower receiver (the firearm component) and the bolt carrier group is optional. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.
Choose your handguard!
Sure, the upper assembly comes to you prebuilt, but you still have to install the handguard. Why do we do this? Because you get to choose what type of handguard you want your upper assembly to be paired with. Choose one of the following:
- 12" M-Lok free floating
- 12" Slanted-end M-Lok free floating
- 13.5" M-Lok free floating
- 15" M-Lok free floating

Receiver sold separately
No FFL or serialization is required to fabricate a receiver under federal law. However, state laws vary. Some states require serialization or have banned 80% lowers and gun-making kits. We encourage each and every builder to perform their own research about the state and federal laws that apply to them.
Shipping Restrictions
Shipping of various parts and/or accessories are prohibited to states and locales (ie New Jersey, California, New York, etc…) with restrictions against certain parts and/or accessories or “assault weapons” (i.e. states with high-capacity magazine restrictions, manufacturing of semi-automatic weapons, etc..). It is your responsibility to be aware of your local firearms laws before purchasing from our website or machining a firearm. We try our best to keep our shipping page current, but laws change daily
80-Lower.com only ships within the United States. Federal legislation dictates we cannot ship our products internationally.
