    As lot of people mention Toolcraft. A couple years ago I was curious so I looked into it a bit. Toolcraft (at least at that time) only makes the carrier, which is the least likely part to fail. They even state that they can supply bolts from different vendors if requested. I believe that when Toolcraft complete BCGs are offered for sale retail they may come with more than one bolt type. This fact is sometimes mentioned by the retailer, but they do not mention the bolt manufacturer, and do not go into much more detail about the bolt.

    Personally, my budget allows me to buy any grade I want. And I've been mostly buying BCM, although I have been using DD, LMT Enhanced, and Colt. I've tried cheaper too, but my first try with PSA was a disaster, so I don't buy or use the cheap ones except to keep them as back ups to back ups.

    As mentioned above. I'm not into coated bolts. Except the two LMT Enhanced BCGs.
    I too am not a fan of coated bolts and carriers. All the experience I have had with nickel boron has been a disaster. That being said the Sionics NP3 is the real deal. For any suppressed shooting I think it's a must. The whole "carbon just wipes off" myth is totally real their BCGs. I have had nasty, suppressed, dirty, +1k rounds of 300 blackout where you have that awesome caked on mix of lube and carbon. Hit it up with a little M-Pro7 and it just cleans right up. Its magical but you pay for it.

    The Small Arms Solutions video posted a couple pages back was interesting regarding "Enhanced BCGs", but the only enhanced BCG i would buy (and did buy) for a "GO TO" rifle is the LMT enhanced. It has been though a few generations of improvements and is most improved where it really counts...in the bolt.

    Other than that, if you're worried that your BCG won't hold up when it counts, the best way to mitigate common failures is to buy a spare bolt and keep it ready to go in your grip. You just have to hope it doesn't happen at an inconvenient time.

    A bolt holder can be purchased for a Magpul MOE grip.

    Those older posts are for the people who haven't read them before and don't know or don't understand the facts and issues regarding BCGs. We can't have a really informed discussion unless everyone has read the same material. These new posts like this have some inaccuracies and no body who has read those old posts wants to go back and re-litigate discussions.

    Maybe I'll try one for fun. You are talking me into it.

    IMHO, other than being not only slick as hell, NP3 can also be pretty hard. Having it on the carrier's upper contact surfaces will give it an edge vs an untreated one, with reduced wear on contact surfaces and extend the run time a little more before there is a malfunction when it’s really dirty or when there is little lube present.

    I beg to differ. For some their body of knowledge in metallurgy, heat treatment, materials science, and non-destructive inspection comes from technical education and relevant professional experience (25 years in my case). They don't get their knowledge from the internet.

    No. And whether I or anyone else did or didn't has nothing to do with the topic at hand.

    I think it does.

    What's the color of the boathouse at Hereford?
