Radical Firearms is a company that offers a lifetime warranty on all their manufactured products. This includes rifles, AR pistols, and suppressors. They custom build every order as they are ordered, which can lead to a 6-8 week lead-time. It's important to note that they advise against using Remington UMC ammo in any of their firearms.
For shipping, they will gladly ship your firearm purchase to your local FFL. In order to do so, they need your FFL to send a scanned copy of their FFL license to a specific email address or fax a copy to a specific number. It's crucial that your Radical Firearms order number and customer name is marked clearly on the FFL paperwork. You are responsible for ensuring that the firearm is in compliance with all local and State laws. All shipments of firearms require an adult signature at destination. It may take up to 2-3 business extra days to process your order once FFL paperwork is received.
They also have an owners guide section on their website where you can find supporting documentation on Radical Firearms manufactured firearms products, and gear. They continue to update this section as more product becomes available. They are also ISO 9001:2015 Certified.
Remember, for any inquiries, it's best to reach out to their customer service via email.
