GunBlack for parkerizing services... in the Northeast
Shuff's is well known and his reputation is well deserved, but I was looking for a vendor, with a comparable reputation and one that could handle a complete M700 barreled action (Shuff's can't,) who was on the east coast and closer to my gunsmith and stocker. I contacted them via their web site's internal mail and did not keep a copy of my correspondence, but the content of their response was very complete. I tried, but the green parkerizing finish, regrettably, was out of the question. I'm going with this outfit...

Good morning Mr. Bolt_Trash, and thank you for your interest in GunBlack's services. The term Parkerizing can mean both Zinc Phosphate and Manganese Phosphate. The United States Military has always preferred Manganese over Zinc for small arms. The same goes for Remington Arms in Ilion NY. Both Remington and the Department of Defense are important (and big) customers for GunBlack. Manganese and Zinc Phosphate have always been a medium-dark gray in color. Green tints in the coating came from poor chemistry during war-time production and elements in cosmoline and other heavy grease reacting with the coating over a long time. Some shops use pigments in their oil rinse to color the Parkerize coating but that does not conform to the Military Specification, so we do not provide it. The chromic acid contains hexavalent chromium which is nasty, nasty, nasty. It is carcinogenic, toxic and all around bad news. I do not know why it is still in the Mil Spec because the DOD also requires contractors like GunBlack to NOT use it in our process, for any components that come in to contact with human skin. Mil Spec Parkerize (Manganese Phosphate) is the correct coating for your Remington Sniper rifle and a superior firearm finish to Zinc Phosphate. Zinc Phosphate is usually used for automotive parts.
a) The barreled action can be coated as a single unit. This is also the way we coat rifles for Remington.
c) Turnaround time is less than 2 weeks.
d) Thank you for the opportunity to quote you.
Best regards,

Just a note, that I did, in fact, contact some other NE outfits that advertised providing parkerizing services and other than Shuff's, who is a consummate professional, only two (2) in five (5) actually even bothered to respond.
