AA Chrome bolt
Has any one received a new chrome bolt from AA recently? I ordered one 10 months ago it just showed up today. The bolt is black and the invoice says chromed bolt, extractor uct coated. My quistion is the bolt is black colored ??? I was expecting it to look chromed? any body have any knowledge of these new AA chromed bolts?
AA has been in the process of a switch to an Ion-Bond process, which is superior to hard chrome, both in lubricicity and wear, as I understand it. I suspect that is what you received.
I'm glad these are showing up!

I'm expecting one to be delivered from the brown Santa this afternoon... will let you know what I receive
Mine just showed up... it is black like yours roto-prop. It has a relief cut on the lug opposite the extractor. I must say it's an impressive looking piece of steel. My only complaint (besides the nine month wait) is the $16.95 for freight seems a bit steep.
Yes mine looks very well made and looks the as you described yours johnOD . Now if my barrel from Satern machine ever comes. I get a little worried when I e-mail them asking about my order and they reply back with no ET Yet for the barrel but ask me if I would like something that I had already requested in my original order. I must say though this is a nice looking bolt from AA was a long wait though. I was hoping to try and get a muley deer this fall with this gun but I do not know if I will have it done and a load worked up by then. Sure glad I have not been in a hurry to build this rifle. lol
If these bolts have a kind of sheen to them, and are extremely hard on the surface, that is nitro-carburized, aka ion bond, aka Melonite, aka quench-polish-quench, gas induction, and so forth. Very tough metallurgy that blows chrome away really. You're looking at a Rockwell hardness of 65-70 usually from what they normally get with those treatments.
The barrels I have that are nitro-carb'd will take a metal file like water off a duck's back.
