AR takedown pin tool

[DennisH82]

My knuckle always worked for me.

After putting together my first AR many years ago I learned to always have two "oops kits" purchased and handy at all times

I bought a weavers armorers kit for the ar at walmart.com Its got everything to build a upper and lower.
I lost the little cotter pin that holds the firing pin in.. I have no idea how I lost it, put it in the cleaning bowl and it was gone.
I'm not going to order one, home dumpster has tons of them.

In the past a straight edge razor out of a box cutter would work for me. But as I get older - everything seems to get harder and it doesn't work well for me anymore. I think once I master this tool it will work best for me.

A quarter inch hitch pin works the same way for just a couple bucks.

I used a chop stick. Easy peasey. Also used it to help push the pins out till they loosened up a bit.

You guys would fall out of your shoes and piss yourselves laughing if you saw what I use to put roll pins in. Works effin perfect. Made it from a hunk of scrap steel rod. Long, chisel thickness at one end (easy to hold!), thin at other and polished.

Dad was a deep coal miner. We was po folk. You would make it before you run out to buy it, if you even could buy it. Depression era parents. Would not trade my childhood for anything.

I was also going to suggest a properly sized wooden dowel cut at an angle on one side.

In the early to mid 70s Colt Manufacturing removed the cotter pin from their AR 15s and M16s and replaced it with an alternate device to secure the firing pin in the bolt. However they eventually went back to the cotter pin which inspired the TV sitcom "Welcome Back Kotter Pin".

razor blade

Waste of money. A razor knife is all you need to hold the detent in there while putting the pin in place.

Great that someone can make money by selling needless tools though. God bless America!

That was a good show.

I use a .125 drill bit that I ground the shank side to a point to drive home my roll pins.

For the pivot pin I use a toothpick with point sanded flat to push the detent in and load the spring then take a small jewelers flathead to capture the spring. I prefer this over the razor blade method because if you are careful you can remove your hand from the flathead and work with both hands.
