I set out with one goal. To create the lightest full-size, accurate, functioning AR-15 using commercially available factory parts. I didn’t cut anything off nor drill holes: every one of these parts is as strong as when it left the manufacturing floor. The end result was a rifle under 4 lbs. Even with a suppressor and red-dot optic, it came in under 5 lbs. The result is Ignisspir or Firebreath.
