NP3 is a great finish and is very slick…but it just doesn’t seem hard enough to stand up to metal to metal contact. I don’t think it would last all that long on a BCG. The FailZero finish seems to be more durable in this respect.
I have a USP with an NP3’d slide and pretty much anywhere metal rubs against the NP3 finish, it has worn through to the metal…And all I’ve done with the pistol is rack the slide a number of times since I had it finished.
although i do not suffer from carbon build up as the DI guns do
it would be nice to have something that does not require lube…
i called Failzero and ask how their coating would fair on anodized aluminum
the gentlemen replied that if i was going do competition or any sort of serious uses that it would be preferable for me to get the upper coated as well.
now i know a thing or 2 about materials and manufacturing being a Mechanical eng. but i am left speechless about these treatments and information is hard to come by.
i wonder how the upper receiver fairs with no treatment… since the boron coating is harder that the bolt carrier material is there an increase in wear on the receiver ???
very cool thanx for the tip but from what i understand reading about ion bond is that
it does reduce the coefficient of friction and does require some lube.
after thinking about it for a second it seams more realistic than the other claims…
I put more than 2k rounds through my SBR with an M16 FZ BCG with no cleaning and no lubrication (not even any to start with) with very good results. No way a regular BCG is going to do that without lube.
I would not classify the wear as, “excessive” in any way. To make any viable judgement, I’d have to see the innards of an SBR with a similar round count.
