NiB vs Standard bolt carrier groups

What makes NiB premium to the standard 9310 MPI

Carbon doesnt "bake" on unlike standard bolt carriers. Easier to clean and is lubricous so less lubrication is required for smooth running. For the average shooter it will just be easier to clean.

Standard BCGs are so cheap nowadays...$75 + free shipping at AIM surplus. Wanted to understand the difference before I ordered 10 of them

To be honest, if you arent shooting 500 rounds a week, the stabdard bcg works just fine. $75 is a good deal.

Basically a lower friction coefficient and easier to clean coating. Some manufacturers do a better job with coatings the nib than others, do research before you buy.
I have a nib 308 BCG that runs great.
I also have two Aim nib 5.56 bcg's, haven't used either. They do look great and have no noticeable bad machine marks on them. I don't who makes them for Aim but as I said, seem like good quality.

I'd go with a NiB from CMMG. My friend bought a Wilson upper with a NiB BCG and it really is that slick. Feels like butter with no oil at all... And easy to clean. Plus it looks awesome too.
Or you could go ultimate bling and get a TiN BCG.

Salient sells the TiN BCGs for around $350.

There's absolutely no practical reason to spend more on NiB. Mil-spec phosphate coating with the proper amount of CLP on it allows carbon to wipe off easily. A solution in search of a problem really. I've burned through hundreds of rounds as fast as I could swap mags with an A2 set to burst and as filthy as that bcg was it still wiped clean just fine with just a rag.

I do agree, its unneeded. I have a nice one riding in a a 308 and it is the tits.
But, how else am I gonna be "tier zero while operating operationally with my tactical kit as I operate while watching magpul dynamics videos"

NiB and TiN are more tacticool. They are necessities.
After holding a NiB carrier I can see the benefit. Cleaning is much easier and lubricity is much improved over a phosphate carrier.
Is it necessary? Probably not. Is it an improvement? Certainly.

Yes, although I always come back to my 20" A2 type rifle. You spend a fortune with SBR's, handguards, red dots, optics, bcg's, etc...yet the A2 makes me smile the most. So accurate with irons, just a perfect rifle.
Not mine, but just in case people forgot what it is.

My first upper purchased was a 20" DPMS Hbar. That thing is unbelievably accurate. I was shooting golf balls at 100 yards with ease.
The 12 power scope helps a little bit though...

I have doubts on how much of an improvement those coatings are. Claiming it's easier to clean and requires less lube on something that already is easy to clean and requires little lube is kind of a tough sell. Talking taking the CoF from .20 to 0.13 for the lubricated surfaces involved which only enough to care about from an academic standpoint. Claims of faster cycling time is also academic because the very few thousandths of a second difference is meaningless to the tenths of a second your brain needs. Companies are making a lot of money selling those shiny BCG's though...

It is noticeably smoother even to the touch. I agree, totally not necessary.
Cycle times: I prefer mid lengths for the softer recoil, slower cycle time, and so on. The cycle times depend heavily on gas port length and buffer weight. I don't see a big difference in the nib bcg there...
I you like nib, get it. If not, you won't notice any difference in performance.
I can say, my 308 nib bcg is very easy to clean, very.

Take equally-dirty BCGs, one phosphate and one coated, and time yourself cleaning both. I bet you even know which one will be easier cleaned in a quicker fashion.
And I also agree with Murdock in that it feels slicker to the touch.
Like I said before, is it necessary? Probably not. But IMO it is still an improvement.
EDIT: I also made no Clames (lulz) on cycling time. I agree with you that I highly doubt the coating matters in those terms.

Cycle time is one of the claims for advocates of the coating. If a mid-length carbine can go thousands upon thousands of rounds with no cleaning by keeping a plain mil-spec BCG lubed, without failure, then there really is nothing going for the NiB BCG. You are still going to pull it out to lube it, you are still going to clean it and the efforts for either are not significantly made easier with NiB.
