    firing pins

    I have collected a few of them from different places and dumped them all in the same place. Now I can't tell which is which...

    Some are heavy and shiny (I assume steel); others are light and dull (I assume aluminum).

    Which should I be using when?

    I a'm sure there are no aluminum fireing pins ,titanium is made and you may have one of those ,they are lighter than steel .

    I was thinking the same, that perhaps it might be titanium.

    Use a magnet to identify the steel (and non-steel) ones.

    Heavy and shiney sounds like M16 firing pins, maybe really old M16 firing pins.
    Light and dull sounds like current AR15 chrome plated steel pins.
    Use the light and dull pins and keep the heavy shiney pins as reminders of a simpler age.

    No, the dull ones are the titanium pins.
    They will be significantly lighter weight than the shiney steel pins.

    The difference between M16 and AR15 firing pins is not nearly as significant as the difference between steel and titanium firing pins.

    I have only seen two titanium firing pins and they were gold in color.
    Never seen any real use for them personally.
    If someone did make a dull silver finish titanium pin , I'm with the don't use them club.

    If you compare an early AR15/M16 firing pin to a current M16 pin or AR15 pin, the early pins are significantly heavier.

    Randall,
    What are the differences between a M-16 and AR-15 firing pins?
    Do they go with the specific BCG or into the different systems/ semi vs. Auto.
    GOt any pictures to show the differences.

    I have an auto BCG in my 6920 for instance..

    Thanks.

    Jack
