What You’ll Need to Assemble a Dirty Bird Build Kit:

Many first-time builders also appreciate Dirty Bird’s educational content, including build videos and walkthroughs. No prior gunsmithing experience is required—just patience, a workspace, and the right tools.

This depends on your location and the specific configuration of your build kit. Some California-compliant options are available with featureless stocks or fixed magazines. However, it’s your responsibility to ensure the parts you’re assembling meet the legal definitions in your state.

For buyers in restricted jurisdictions:

  • Be aware of barrel length and brace/stock combinations
  • Use a fixed magazine device or compliance parts
  • Avoid flash suppressors or adjustable stocks where prohibited

Dirty Bird Guns & Ammo offers helpful compliance tips and provides limited options for CA-legal rifle kits. However, always verify with your local laws or an FFL before assembling.

Dirty Bird Industries stands behind its components. Most Dirty Bird build kits come with a lifetime warranty on manufacturing defects. If you experience any issues with your kit, Dirty Bird’s customer service team will work with you to repair, replace, or provide a refund for the affected part.
