Default Black oxide touch up?

I had the CMP custom perform the shop black oxide (matte) treatment on some 03A3 parts recently. I did not send them the rear sight as I did not want to remove it. Is there anything available that I can use to replicate their finish without removing the sight and harming the parkerized finish on the receiver?

Thanks

I've used Caswell's Stainless Blackener with good success on steel parts. Especially things like M1 front sights and A3 sights. You can't leave it on for very long...only till it blackens....then rinse with water and oil it.

Thank you for the reply, I'll give it a try. I can practice on some on some scrap parts first.

Caswell's does a nice job. Be careful about where you do the touch up, I'm replacing a sink...at Cinc House's direction!

You got off easy, I am now Off Limits to oven, sink and dish washer. I know to take my projects elsewhere ...anywhere but stay clear of the kitchen.

Anyone who does gunsmith work in the spouse's kitchen, does so at his own peril.
