I posted a few threads regarding who should hard chrome plate my bolt for my AR-10, I did not get much response. Before I posted my questions, I read a thread or two on this topic. There were several who named a company that does this process properly. I think I found it but if you know, please confirm it. BTW, the price for this was $50.

Accurate Plating and Weaporyry AKA Cogan Custom will do ANY small parts for $50.  THey will do you whole trigger, disconnector, hammer, bolt and bolt carrier if you wish or just the bolt and carrier.  You have the best company with the lowest prices.  Tripp is good too but too expensive.  I like the looks of Armoloy but the vapor honig process causes a slight roughness to the finish that trapps crub and makes it a pain to clean.
