Important Procurement Note (NFA Regulation & Age Requirements) The Daniel Defense DDM4 300S is classified as a Short-Barreled Rifle (SBR) and is strictly regulated under the National Firearms Act (NFA). Under U.S. law, purchasers must be 21 years of age or older, and transfers require federal NFA paperwork, approval processes, and Class 3 dealer facilitation.
