AR 15 Firing Pin Retaining Pin, aka Firing Pin Retainer, aka AR 15 cotter pin, aka that forked pin that is sometimes a pain to reinstall.
Maybe you’ve lost yours. Maybe you’ve bent it. Maybe you got frustrated when reinstalling it and tried to hammer it in, and learned that hammering it in doesn’t work and destroyed it. Regardless, it’s good to have a few spares, right?
Turn them sideways (fork horizontal) when installing, and press down a little bit when pushing it through the other side. Some take a bit of wiggling to get aligned just right when going through the other side of the carrier.
Cotter Pin – AR – Great service, fast shipping, and product I received was exactly as I was looking for! Great Job!
It worked – Nothing special, it retains the firing pin as advertised. I bought 3 which should last me a long time
sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
