  • Model:  The Vault

Note:  We mill the lug pockets for the upper receiver slightly below the specification.  If your upper is at the top of the specification, you will have a snug fit.  If it is out of spec on the high side, you may have to stone the sides of your upper receiver lugs to fit.  This is a feature, not a bug. 

This is considered by the ATF to be a firearm and must be shipped to an FFL for transfer to you. These cannot ship directly to your residence. Please be aware that because these are not long guns, you must be 21 to take possession of them at your dealer. Returns due to failed transfers will be accepted with a 15% fee and return shipping covered by the customer. Customized lowers cannot be returned for any reason other than manufacturing defect. Any transfer fees charged by the transferring dealer are the responsibility of the purchaser.

We must have a copy of your dealer's FFL prior to shipment. You will be able to select your dealer at checkout.

    Fallout Tribute Lower - The Vault - AR15 Lower Receiver

    Posted by Jeremiah Walker on 18th Jul 2026

    Top notch quality, flawless finish, tight tolerances, and great fit.. I’m 100% satisfied. I paired my B.A.D fallout lower with Aero Precision upper for a 10” 300Blk pistol build and’s couldn’t be happier with the finished product. I would 10 out of 10 Recommend Bad Attitude Dept.’s products to anyone wanting to build a custom AR. The only complaint that I have, is that on the website it clearly says that the “Ambidextrous lower accepts HK416 and Sig MPX ambi bolt catches” and this is not the case. It accepts Sig MCX ambi bolt catch, which I only came to realize after purchasing $60 Sig MPX bolt release hardware, for it to not be compatible. I did email B.A.D about the issue and they confirmed that the website info is incorrect and the Sig MCX was the correct bolt catch. Although at the time the of writing this review the information hasn’t been corrected on the website.

    Phenomenal quality, paired mine with a DDM4v7 upper and it’s my new go to rifle. Wish I would’ve bought more

    Good Quality lower the only thing that would make this better is if you can pick the vault number
