Dirty Bird AR-15 Lower Receiver Pin and Spring Kit

Dirty Bird Industries' pin and spring kits are everything builders need and nothing they don't.

The kit includes the following mil-spec parts: 

  • Trigger / Hammer Pins (x2)
  • Takedown Pin 
  • Pivot Pin 
  • Takedown / Pivot Pin Springs (x3)
