i'm new to AR's, and i've done a search for the past 3 months and i couldn't find anything. i put mine together from a kit from JTDISTRIBUTING, but as i was looking through cheaper than dirt, it had a pin replacement kit with a cotter pin, i didn't get one in my LPK, dunno if there is something that replaced it, but i'm curious.. thanks for the help. |
That pin is a very important piece of the AR...make absolutely sure you put it BACK when you re-assemble the bolt/carrier after cleaning. IIRC, the Marine Corps manual mentions the words "death" and "serious bodily injury" in conjuction with firing the rifle without it  The prongs on this piece tend to get bent a little through standard wear and tear, so it can sometimes be tough to get back in...on some of my mine, I need to push down one of the prong a little to get it to go into the hole in the other side. You might want to order some spares, just to keep in your parts box...they're pretty cheap. Also, DPMS makes a solid SS pin that replaces the cotter pin...I've got one of those in my DPMS .308, and they are very cool. |
I can't picture how that would happen with the FP retaining pin. I think it's the cam pin they print that warning about. |
you might be right...but I know there's a warning about something some pin. I guess it's a good idea to have them all where they should be....although I don't know how in hell you could reassemble the bolt/carrier w/o the cam pin.  Forgetting the retaining pin is a little easier. |

I think you'd notice if you left the cam pin out when you go to reassemble... But without it the locking lugs wouldn't engage and the bolt would open instantly upon firing and that would result in a KB. I think leaving out the FP retaining pin would just make it jam on bolt closing or hang up the hammer. But as you said, all parts in place when firing is a good idea... |
