Discussion on BCG finishes
Trying to compare the following:
DLC, TiN, chrome, nickel boron, robar NP3, melonite.
And to determine which ones can be done on a milspec bolt and carrier.
From what I understand, melonite must be done before heat treating.
NiB is tougher and slicker than chrome at a reasonable price.
Is there a way to chart and compare?
Spikes FZ BCG experiences
I have and run a variety of BCG's (DD,Stag,Olympic, Noveske,Spikes,AA.) I am not a LE/SF/Mil operator, but I do shoot and build a fair amount of AR platform. I am personally sold on the FailZero/EXO coating though. I have purchased 3 of these units to date (2 in 5.56 and 1 in 6.8 SPC.) They are the smoothest BCG's I have ever used, several friends that have shot the platforms have commented on them comparing them to their own rifles. I was paying about $160 for my DD BCG's and $60 bones for the FailZero coating on such a critical part is a no brainer for me personally. Clean up is also a breeze comparably. I highly recommend, do a search for FailZero torture tests on google for some demonstrations and make your own call :)
