To end the NiB argument once and for all...

[Regalkismet]

Thread is about deficiencies in NIB vs. uncoated.
Physical threats over the internet? Who needs to grow up now?

Do you comprehend much? Show me the threat?

[Digital_Damage]

I seem to be able to comprehend more than just three products... so I at least have that going for me.

I'm done, in this thread.

Two things. First I have 5 AR's and one AR-10, all using NiB BCG's. I am not trying to refute any of the evidence in the referenced PDF, however, I've conducted two very non-scientific tests that makes me glad that I have them.
1. They take very little lube to achieve the same performance of a phosphate bolt. According to the OP's original post, they offer a lower coefficient of friction. That in itself should tell one something.
2. Here's what reduced coefficient of friction proved to me. When I bought my very first NiB bolt about 2.5 or 3 years ago, I took two rifles to the range and my Fluke meter. I dumped a mag as fast as possible with each, and took temp measurements on various places on each BCG with the temp probe with my Fluke meter, and the NiB ran at least 10 degrees F. cooler with the NiB bolt over a stock LMT phosphate. Not sure if 10 degrees would make anything other than a measurable difference, but it almost certainly proved that there was less friction with the NiB. I let those rifles cool to ambient, and repeated that test 3 or 4 times (don't remember for sure) and the results were nearly identical + or - a degree or so, either BCG.

I have never experienced flaking or anything else out of the blue using, NiB, and I'd swear in court that my guns run smoother with NiB. That's subjective, and obviously I can't prove it to you, but I've got no reason to fudge here, I have no vested interest in selling folks on NiB BCG's.

Lastly, and this may be very minor or totally insignificant to many or all of you, but cleaning is a big plus to me. I like the fact that I can spray them with a shot of gun scrubber, and clean them off with a piece of T-Shirt. Bolt tails might have specks of carbon, which I can normally "scrape" with my thumbnail. Job finished, onto the next gun.

I'm retired military, and although not an armorer I've had my friggin fill of scraping carbon off of bolt tails, it's a PITA and being able to scrape "specks" of carbon with my thumbnail and a shot of gun scrubber, rather than having to use a tool and scrape a coating of carbon off, makes NiB worth it to me.

In summary, I'm not trying to sell anyone on NiB, nor justify my use for them, nor debate the fact with armorers or other experts in the field of coatings, plating or whatever, just stating my experiences with them, and the fact that I've suffered none of the negative qualities that some have pointed out.

Everyone needs to step back and riot for a little bit. No need to get worked up. If you like your NiB coating, you can keep your NiB coating.

If you look at previous information posted, you will see it has to do with who did the work. NP3 is done by very few if any (AFAIK) which means the quality control is much tighter and controlled.

Thinking I want to get one of the NP3 bolt groups from Sionics. Is it recommended to use the standard bolt or get the group with the NP3 bolt?

I have a ton of respect for the science that Andrew has brought to the gun community. This is all I needed to see to never buy a nib bcg.

[Iraqgunz]

It doesn't matter to be honest, but the obvious benefit to the NP3 bolt is that it is easier to clean. Prior to selling the entire NP3 BCG we sold the standard bolt and cam pin with the NP3 carrier.

Is there any potential excessive wear by running an NP3'd bolt inside a regular chrome lined carrier? i.e. I'll assume that an NP3'd carrier is also NP3'd inside where the chrome lining usually is. Since chrome is harder than NP3 I just wondered if chrome-on-NP3 would wear it faster.

Entertaining the idea of a NP3 carrier for my suppressed SBR 300 BLK build I'll be starting soon. One thing I like about standard phosphate carriers is how they "absorb" lubricant and how this makes cleaning much easier later on. Squirt some FireCLEAN, wipe off, re-apply. I'm assuming NP3 doesn't "absorb" lubricants into it's pores like a standard phosphate carrier/bolt, correct?
