Best AR anti-walk takedown pin?

[Good_Knight]

I'm looking for one for my older AR that cannot move unless you remove the "hair pin" going through it. I just can't remember the brand. Thanks.

Just read that you wrote take down pin not trigger pin....not sure about that one

[Sicarius]

Takedown pin or hammer/trigger pins? Colt made a forward takedown pin that used a screw. These came on their "sporter" uppers. If you are talking hammer/trigger pins, KNS is the way to go.

You just need to get the diameter and length and go buy one at the hardware store. I do not ever remember seeing a take-down pin that used a cotter-pin or R-clip. I use a KNS screw pin on my Pivot pin, I know old Colts used screw pins. Never seen what you are asking since the R-clip would dig into your hand, or snag on gear....which is why, I would assume, they never really caught on.

It's definitely the takedown pin that I'm looking for, just the rear one to be exact. Maybe what I saw once was just totally custom. The problem I'm experiencing is that when I lay the rifle down or even just slightly touch the rear takedown pin, it "walks" out of the receiver too easily.

ush button rear takedown pin - kind of the same concept as the quick connect sling mounts.

KNS precision makes a pivot pin like that, never seen a REAR takedown pin tho

do you have a good working takedown detent installed properly?

[Panchira!]

I have the kns push button pins like the pic above and they work great! Easy to use and will not come out. A bit pricy but they work great. I got the standard one for the rear and one that has the sling stud for the from.

I have a similar pin and it has a screw on one end and a push button on the other. What's the screw part for?

Try using an accu wedge in between the upper and lower, probably gona give it enough tension to fix the prob. If its that loose to come out that easy then you probably have a good amount of play between the two anyways that could also be fixed

I think Bushmaster has something like that?

That really is just a cure for the symptom, not the cause.

OP: if your take down pin is coming out that freely, it means one of three things is wrong, your take down pin is damaged/ wore down on the groove, the detent is damaged, or the detent spring is wore out/ damaged, or some combination of the three.

My suggestion, and it keeps the rifle normal. is to just replace those three parts, should take all of about 5 minutes and should cost roughly $4.50

I wish my takedown pins came out easy. I think 1 of my lowers is out of spec because I need to use a hammer to get them in and out.

many are like that. its not out of spec, just a case of tolerance stacking. it will get better with age.

Sounds more like you smashed the detent spring when you put the buttstock on. No pressure on the detent, means no pressure on the take-down pin.
