*UPDATE* Need some advice on an AR purchase

[farmerj]

you can't "fix" that kind of damage. It's done at the chemical level and you would have to replace metal then.

Imagine someone dumping battery acid on the hood of your car.

Partly why I am hoping you bring it with next weekend.

I have known this guy forever and he would never try to screw me over. Should I just ask for my money back and return the rifle?

I'd rather look at it in person before saying.

Did he use it as a truck gun and did it just bounce against something hard and sharp

He acknowledged that it looks like some kind of acid got on it and ate the finish, but he also said that it hasn't gotten any worse since 89. It kinda hard telling how he used it but he said that he only had about 500 rounds through it.

As long as it's structurally okay, you should be fine. It's ugly, but that's okay.

Getting back to some previous questions, it looks like the lower is a Sporter II (R6500), but the upper isn't correct for a 6500 because it has A1 sights. Does it have a brass deflector?

It doesn't have a brass deflector, but it looks like the picture that Joe H posted on the first page of my post.

I wouldn't call your rifle ugly.

I would call up colt and say it's an older gun and the metal it flaking away. Ask them if you can send it in for them to look at and see if it would be covered under warranty.

That's what my buddy said I should try to do. I guess it cant hurt to ask and see what they will do.

Looks like all it needs is a bead blasting (to make it less ugly) and re-anodizing.

to me it looks more like some kind of Galvanic corrosion, where something that had electrical power, like a car wire, had come into contact with a wet patch on a gun case. I see props on boats that look like that when the sacrificial zincs wear out.

Colt said to send it back and worst case is they will refinish it for 275 bucks. I am not sure how they can refinish it, but I will send it back and see what they can do.

FYI, they said from the SN it was manufactured around 86-87. They also said that later models 89 and up had a sear block ???? and could not be refinished

The sear block prevents you from adding a full-auto sear; not sure why they in particular can't be refinished, though. Do a GIS for "colt sear block" if you're curious to see one.

Let us know how this turns out. I'm impressed Colt is being so helpful.

I just came across this post and think i know exactly what that is, Simple Green burn, looks exactly like the markings I had on some lower control arms I cleaned with simple green and left covered with a rag for the week until I got the chance to finish the job the following weekend. Glad colt are helping you out.
