These kits often come with pre-selected components designed to work together seamlessly, making them an excellent choice for first-time builders.

What tools do I need in order to build my own AR-15?

  • Vise
  • Receiver block
  • Punch set
  • Armorer wrench
  • Torque wrench

Additionally, specialized tools such as a drill press and milling machine may be needed depending on how much customization you want or if you plan on machining receiver out of 80% blank yourself instead of purchasing pre-machined blanks.

Can I customize my completed AR-15 without violating any laws?

Yes! Customizing your completed ar 15 without violating any laws is possible but there are certain limitations based on federal regulations under both NFA (National Firearms Act) & GCA (Gun Control Act). For example: customizing the barrel length below minimum requirements could result in violation under NFA Title II while using illegal accessories such as suppressors would violate both NFA/GCA provisions unless specific licensing was obtained through ATF beforehand.

Other than these specific cases, most customizations can be done legally including changing furniture like stocks/handguards/trigger guards/grips/sights/optics/accessoriesetc., adding tactical gear/attachments etc..
