I recently purchased a SIGSCM and noticed that around any of the releases (safety, etc..) the finish seems to be a little more glossy. Is this something that I should bring to the attention of Sig Sauer, or is there something I should be doing to make the finish the same throughout, or is this nothing to worry about and just live with it.

Thanks in advance for your opinions and suggestions.

Sorry about the size and quality of the pictures, I'm new at this. Hopefully you can see what I'm talking about.

Is the shine from oil creeping from the internals? If I wipe everything dry, the finish is uniform, but the clp does creep while the rifle's stored.

Can't tell, pictures too blurry, and I haven't been drinking....much!

That's my guess also. Both my 556's look like that.

If it's heavily lubed it does. If you store it upright the CLP flows down to the bottom of the receiver and out that space. Any rifle will do that if you really lube it up. I don't like to store it wet like that because it attracts dust and dirt. If you wipe it off and it goes away then you are fine. Have you wiped down the exterior with CLP?

Sorry about the pictures, I'll thy again.
The rifle is new out of the box like this, I haven't touched it. My concern is doing something that I shouldn't do, and making matters worse (in Sig's mind).

...use a lint free rag and try wiping down the reciever...use a rag moistened with Breakfree CLP...wipe down the recievers...let set a while...then wipe off the CLP leaving only a slight film / trace on the surface...

...you should wipe down all the metalic surfaces...inside and out.. with a rag moistened with CLP...let set a while...then wipe most of the CLP off...leaving a slight film to act as a corrosion inhibitor...then properly lubricate the weapon before firing...

Thanks ullie, I'll have to wait for this weekend to get some CLP.

Here are a 2 more pictures that hopefully should be clearer.

Thanks again for all of your help.

...liquid lubricants...especially those containing solvents...migrate and sorta creep...especially around the pins...for example... when you lubricate the internals of your lower...and wipe the outer surface of the reciever down...days later you'll notice a "wet" ring around the pins and some other areas...that's perfectly normal...

...in your pictures...the lower reciever really really looks dry...you should season it with CLP...after you wipe it down with CLP...it "should" darken and look more even...

...if the lower doesn't absorbe some of the CLP...and doesn't balance out in appearance...the anodizing process may not have been done properly...including the improper use of dyes...after liberally coating the recievers inside and out...letting them sit awhile...then wiping them "almost" dry...they should have a relatively even finish...without any dry blotches...

...here's some infomation of how to treat your new 556...

Ullie, thanks for the great advise. I read your "How to Treat a New Arrivial" thread the other day and planned on doing the procedure as soon as I figured out if there was anything wrong with the finish of the gun. Now that I received these responses to my problem I feel confident that your procedure will do the trick.

Thanks again.
Brian

Looks like someone cleaned the lower receiver with Gunscruber and didn't oil it.

Break it apart and spray it with some CLP. Let it soak in for a bit and wipe it down.

I bought mine six months ago from SGC. Brand new out of the box. Only shot one time with around 100 rounds. No problem. Did not clean it yet. A month later, discoloration like the one mentioned here appears. E-mailed to Sig 3 months ago, twice. Never received an answer. Called them last week, a nice woman said that she never heard of anything like this from anybody before. She gave me a RMA to send the rifle to Sig to be checked. I did not accept it yet. I tried to rub it off with CLP. No use! I think the paint really got messed up by something. I only shot with Wolf ammo. It may be the reason, but I am not sure.
Anybody shooting Wolf and got this problem?

It appears BSTOCK's last entry sums it up best, patience and a liberal application of gun oil results in desired outcome.

Thanks for the link Sarge. Validates everything ullie said (not that he needed validation). I've ordered everthing I think I'm going to need. Once I've oiled it and let it sit, I post the results.

I would like to thank all of you, especially ullie, who posted opinions and suggestions regarding the discoloration problems on my 556. Once I tore it down and used CLP on it as recommended in ullie's post, all is well. Now all I have to do is find time to get to the range and shoot it.

Thanks again,
Brian
