- Available for residents of all 50 states
- Includes all parts needed for your build except the lower receiver
- Ships directly to you—no FFL required for the kit itself
- Choose between:
- DS-15 MOE – 16" Black, Standard or Fixed Mag

IMPORTANT: If you complete your build using a DSI lower receiver, your rifle will be backed by DSI’s transferrable lifetime warranty.
If you are an instructor or armorer that gives build classes you may, apply to become a dealer.
