THE IMAGE ABOVE IS A PAID ADVERTISEMENT I got a lower receiver 2nd hand and it has YHM oversize takendown pins. I switched out the rear pretty easy by removing the castle nut and swapping it out. The front, however, I have no idea. I have installed many front pivot pins but never un-installed one. Is there an easy way? |

The hole for the detent goes all the way through the pin, it's just smaller than the detent.
Pull the pin out as far as it will go. Use a safety pin or something similar to push through the pin hole from the front. Rotate the pin a little bit so that the detent is no longer in the pin channel. Point the lower at your cat. Pull the pin the rest of the way out. If you want you can put a plastic bag over the front of the receiver or aim it into a box instead of pointing it at the cat, depending on whether you want to keep the detent and spring. [edit:] come to think of it, not all pivot pins have a through-hole. If it doesn't, you'll have to use a small pick or something to hold the detent back out of the pin channel then pull the pin out. |

Funny, I was just thinking about placing a set of those YHM over sized pins into my Wish List at Midway.
I use a small flat-bladed screw driver in the detent channel (of the pivot pin) and pry the detent into the receiver. Then rotate the pin so the slot is not facing the detent and slowly pull it out while cupping your hand over it all to catch the detent & spring. |

You can make a pin removal tool with a small nail or piece of wire, or an appropriately sized allen wrench, and a file.
On a short leg after a 90 degree bend, file the end into an angle, with the point toward the outside of the piece. Open the takedown pin, put the tool in the slot, push tool in and the angled face will depress the detent. Rotate the pin, then remove it as mentioned above taking note that the detent and spring will take flight. |

If you are not planning on using the pin again...
Dremel, with a cut off wheel. Push the pin out, and cut the head off, slide it thru the hole. |

Wow, talk about overkill.  All one needs is a small flat-bladed screwdriver that fits the width of the detent slot in the pivot pin. It's as simple as prying the detent back into the receiver with the blade tip while you rotate the pin, then pull it out. Even a pocket knife tip will work without unnecessarily destroying parts. |

Box cutter blade? Good for install and removal.

i just use a bent pointed dental pick, slide the dental pick up into the pivot pin chanel, push the detent down and slide the pin out with the dental pick. took me a couple tries to get it down but works effectively
