I need a hinge pin made for my sig 556.

[Benny762]

So yesterday I shot my sig 556 for the first time and was really enjoying it until the pin in the hinge launched out and bubblegumed up my glasses. There is a little snap ring on the bottom of this pin that holds it in and it's a common failure.

Anyway I'm hoping to find someone that can turn a piece of rod stock and thread the bottom like this guy did. I've included a pic of the orginal and what I'm looking to have made. Reach out to me if you think you can make this happen thanks!

I'm a machinist. Looks like an easy job if you had accurate measurements to work from.

OP probably has the snap ring sample to work from.

I have the orginal pin. I imagine you can take measurements from it and just add a little extra lenth for a screw

why not call sig and have them send you one

This is a poorly engineered part and common point of failure. The snap rings break pretty often and I'd rather have a small nut I can put thread lock on.

I'm sure they would, but I was going to add that if the part failed on the first time shooting, I'd be very suspect of a replacement being more durable.

I would also call sig. I get your point of the common failure but they need to know that it's a poor part and maybe by now they've fixed it with a more solid replacement.

The USA SIG 556 has not been in production for years, I cannot imagine they have parts available anymore.

It's a discontinued item. This is a sig 556 which is a AR mag clone of a sig 550. They were discontinued somthing like 10 years ago.
