AT3™ MOTHERFU-BAG™ AR-15 Lost and Extra Parts Kit - Springs, Detents, Replacement Components


Replacement Cam Pin for AR-15

The cam pin is a crucial component in your AR-15’s bolt carrier group.  It rotates inside the bolt carrier as the bolt locks and unlocks in the chamber, and keeps you safe from the incredible pressures present when a round fires.  A cracked or broken cam pin can have serious consequences because of overpressure, and could lead to other forms of wear and damage to your rifle.  If you’ve got an issue with yours, it’s best to grab a replacement cam pin for your AR-15.

Unless you like the idea of a straight blowback 5.56 rifle.  (You don’t.  Trust us.)


  • Fits standard AR-15/M-16 bolts
  • Nitride finish for corrosion resistance
  • Mil-spec dimensions
  • Made in the USA
