I removed the FSB on my AR and misplaced the taper pins...
Q1: Can I use "new" taper pins in a used FSB? Or do I need to always use the original taper pins? Q2: Assuming I find the old taper pins, does it matter which one goes in which pin hole? Noob question, I know. Better safe than sorry. |

You can theoretically use new ones, but there does appear to be some dimensional differences among taper pins, even between the two that are already in place.
I have removed taper pins and when I went to re-install them, if they were not in the same hole they came out of, they may have wanted to go too far, or not seat far enough. Swapping them brought them both back to about the same depth as they originally were. Since then, when removing them, I not only keep them in a secure place, I make note from which hole they came. |

Are you sure that the difference is in the pins and not the holes? Maybe one was reamed a little more than the other one? It'd be hard to measure any tolerance shift in the holes , but you could mic the pins and see if there is any difference, although that would be hard too because of the taper. |

If the difference was in the holes, both pins would have sunk too far in the one hole. Think about it. |

They are tapered... The depth of the reaming wil change the seating depth of the pin. And there are tolerances on the diameter. Quoted:

They are tapered... The depth of the reaming wil change the seating depth of the pin. And there are tolerances on the diameter. I know how they work. I am saying, I have removed pins that appeared to be reamed to the same degree because the pins were seated to the same depth. I removed them. When I went to re-install them, one would not seat as far, and the other was deeper than where they both started. I swapped them, and they both seated at about the same depth as before. I did not beat the shit out of them, so they were both sticking out a little further than original configuration. But both were equal in depth. |
