    Chrome bolt Assembly vs standard etc

    Is a coated bolt a good upgrade or is it only a looks type thing.

    I'm just starting to buy fine tuned parts as backups or replace current parts for backups.

    I read titanium firing pins aren't that great so I'm going with a standard bcm pin.

    It is an upgrade at least as far as ease of cleaning goes. It offers extra corrosion resistance as well, but if you're someone that needs that sort of thing, you probably don't maintain your rifle well in the first place. The only worry I would have about it would be the possibility of hydrogen embrittlement if it weren't done correctly. So make sure you buy from one of the higher quality manufacturers.

    I've read that Les Baer and Ruger use them, but I can't confirm that. The reviews I've read are that they are a top notch outfit. Curiously, they refuse to stake their gas key, but according to them, this isn't due to any slacking on their part; it is something they feel strongly about and something they refuse to do.

    I own a carbine with a chrome bolt carrier. The only negative is how noticeable it is when the dust cover is open.

    Isn't that part of the cool factor?

    My carrier is Adams Arms. I only need the bolt assembly. So it won't really shine out when the cover is open.

    Curiosity question: is Metaloy considered one of the "better" ones?

    In an exchange of emails they addressed the hydrogen embrittlement question (of my asking) and replied that they were well aware of the potential and thus took the necessary steps to prevent it. Didn't specify exactly what they did, and I didn't ask, but my understanding is that it involves "stress relieving" the parts.

    They heat it to a certain temperature and hold it for a specific amount of time. I always thought it had to do more with allowing the free hydrogen to "bake out" of the product rather than a "stress relieving" process which is something one usually associates with a heating process that actually changes the iron/carbon relationship of the steel. The hydrogen embrittlement cure is different. Regardless, the process for taking care of the hydrogen embrittlement problem that can occur with chrome plating isn't some hi-tech alchemy; it is well known in the industry, and any reputable plater who says he take the necessary steps to avoid embrittlement probably does what he says he does.

    Why would you want a coated one? What are trying accomplish ?? Better reliablility, wear, cleaning or something else.
