*THIS IS FOR A CARRIER AND STAKED KEY ONLY! These are from a batch that had cosmetic machining issues a few years back, they've been sitting on the shelf and now we are clearing them out. They have tooling lines along the front sides and bottom, where the angle cut is located and also on the ramp. These are cosmetic and should not affect function, we will still allow returns if there are any functional issues.



  • Carrier: Machined from 8620 steel  & QPQ nitride/melonite treated.
  • Improved carrier geometry with M16 profile.
  • The QPQ nitride/melonite treatment hardends the surface to 70 RC and reduces friction, adding corrosion resistance inside and out.
  • Gas key: Machined from billet 4140 with grade fasteners and staked to mil spec.
