Do AR Takedown Pins rust?

[h4344]

Just wondering if anyone has ever found or heard of rust starting on the takedown pins of their AR's. It looks like it might just be some wear and tear on mine but I wanted to check here. Sorry for no pics im at work.

No, I've never had it happen. I would replace them ASAP with quality pins.

I oil my rifle after cleaning, possibly an issue with that?

I've had a set of titanium take down pins. Although it seems silly since the pins dont take a lot of of the forces, the hardness lets them move a lot easier. Like pulling a file over hardened steel, it just glides over rather than catching. The detents also glide over them as well. and they wont rust!

its possible if theyre steel and the coating is worn off

If you see rust, steel wool it off and refinish with cold blue.

Steel rusts.
AR's like to run wet anyway, so those pins should be getting oil by default.

Some pivot pins are brass. When they rub up on the takedown it can be possible to look like red discoloration, similar to rust.

Put them in a highly saturated salt solution, preferably heated, for a week or so and you'll find out. yay

I have never seen brass pins but I bet they do exist. The trigger or hammer pin can be made of most anything that would work. Round stock. Cut down drill bits. We used oversize pins to salvage worn out M16 receivers. Over size take down pins also. Easy and quick to fab if you have the facilities. Like said, a low maintenance part.

I'm in your mind.... that means I've become a cultural force!
