Short answer is, yes. Buying an AR-15 upper online does not require a background check of any kind. You can purchase AR-15 and AR-10 uppers on our website with no background check required. There is also no FFL required to purchase an AR15 upper online. So you can buy as many as you’d like. You can also purchase complete uppers without an FFL license OR a background check.
The AR upper is NOT considered the “firearm,” but the lower receiver is. That’s usually why you hear about the lower receiver the most in the news. That is the part of the AR15 or AR10 that is highly regulated in some states, especially in California. It is the heart of the AR and houses all the necessary components and function to make the rifle work. So go ahead, purchase as many uppers (from us, of course), that you’d like!
So essentially, you can buy all of the parts for an AR online without a background check or FFL. If you buy a completed lower receiver you will need to go through the proper procedures with local, state, and federal law. With an 80% lower that you finish yourself, you will also not need to go through a background check to purchase.
