FAQ

Do lower receivers have to be registered?

No, lower receivers do not have to be registered. However, it is important to know the laws in your state before purchasing a lower receiver. Some states have stricter laws than others. For more information, please contact your local authorities.

Are 80 percent lowers traceable?

The short answer to this question is yes, 80 percent lowers are traceable. However, this doesn’t mean that they can be easily tracked back to the owner. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has a database of all registered firearms, and any completed lower receivers will be added to this database. This means that if a lower is found at a crime scene, the ATF will be able to track it back to the owner.

Is 80% lower a gun?

No, an 80% lower is not a gun. It is a part of the firearm that is not regulated by the government.

Are 80 lowers serialized?

The answer to this question is a little bit complicated. In short, the answer is that it depends on the state you reside in. In some states, 80% lowers are considered firearms and are therefore subject to firearm regulations. This means that a buyer would need to go through a federal firearms license (FFL) holder to purchase an 80 lower and would need to submit the lower to the National Firearms Registration and Transfer Record (NFRTR).

Can you buy an AR-15 lower receiver online?

Yes, you can purchase an AR-15 lower receiver online. There are a number of retailers that carry them, and the process is relatively simple. You’ll need to provide proof of identification and residency, and the lower receiver will need to be transferred to a licensed firearms dealer in your area for pickup.

What does a stripped lower mean?

A stripped lower receiver is a rifle component that is the base of a rifle build. It is called “stripped” because it does not come with any of the finished components, such as a stock, grip, or sights. A builder will need to purchase these separately and install them on the lower receiver.

What are 80% lowers?

An 80% lower is a firearm component that is not classified as a firearm by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE). This means that an 80% lower can be shipped directly to your home without any special licensing or paperwork. Because an 80% lower is not a firearm, it can also be shipped to your home from out of state. To complete an 80% lower into a functioning firearm, you must mill the last 20% of the component using a machine such as a CNC milling machine. This can be completed at home with some basic tools and knowledge. If you are not comfortable completing the final milling process yourself, many gunsmiths offer this service for a nominal fee.

How many AR lowers Can I buy at once?

As of now, there is no limit to the number of AR lowers that you can buy at once. However, some states may have restrictions on how many you can purchase at a time. Make sure to check with your local laws before making any large purchases.

What part of an AR-15 has to be registered?

The lower receiver is the only part of an AR-15 that needs to be registered. This is because it is the only part of the gun that is considered to be the actual firearm. All other parts (upper receiver, barrel, etc.) are considered to be accessories.
