Description
Please Note: Given the current demand for this product and supply shortages, your order may ship with a black hammer and trigger or a stainless steel hammer and trigger.
Check out one of the standards and one of the most lightweight rifle kits in our catalog with a barrel and twist rate that are more accepting of a wider array of bullet weights. This mil-spec AR kit comes to you chambered in 5.56mm NATO, the same caliber as our military's rifles. It comes with an ultra-light, skeletonized handguard that looks great and feels even better. It's all paired with mil-spec lower parts and an M16 profile BCG. And a 1:8 twist rate in the barrel means you can shoot some of the lighter or heavier grain of 5.56mm rounds.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, lower parts kit, and buffer assembly with buttstock. This kit does not include a stripped lower receiver (the firearm component). 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.
Here's the beginner's guide to 80% lowers.

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.
