So I purchased a Specwar 556 suppressor for my spr build and was wondering if having a Nickel Boron coated bcg has any benefits as far a reliability with suppressor use? I know suppressors eat up lube very quickly, and was wondering if this is where Nickel Boron coated bcg’s shine
Thanks
Not really. Oil/lube doesn’t hold onto the Nib coating very well which is accelerated by the suppressor use, and its gets just as dirty as phosphate. Use a good lubricant like FireClean and that’ll give you more benefit than the NiB.
That is one of the niches I see a benefit of NiB, since suppressors eat lube like no one’s business. I was an early adopter of the FailZero and put over 2k rounds through an 11.5 (about half suppressed) with no lube or cleaning whatsoever. There’s a thread here documenting the initial testing years back. Did it four times before I decided to just lube it anyway (action gets really gritty, but still functions, at around 700rnds suppressed).
I recommend using an NP3 carrier or carrier group.
NiB carrier groups are great for use with suppressors. They’re so easy to clean! And they don’t get as dirty either.
There is no downside and the cleaning or should I say (wiping off), is a breeze. I expect it could improve reliability in some guns. I just bought a couple carriers from Sionics for the cost of the coating alone.
I use them with much success.
I have a hard chrome BCG and all is takes is a paper towel to clean it. I do make sure it is prepped with Slip2000 EWL grease and lube and then a few extra drops at the range if shooting a lot.

Suggestions on specific products for NP3 BCGs? And does that mean nickel teflon BCG or NP3 only?
I’ve been wondering if the TR Enabling products are GTG…

NiB sucks for suppressed use. That finish soaks up and holds onto carbon like a magnet.
I ran an NiB bolt suppressed for a while. It looked like a standard GI bolt because it was black all over.
These are still onsale:

EDIT: I needed a BCG for a build, and for the sale price went with this NP3 job from Sionics. Still have zero rounds on the BCG but I assume they are GTG.
I have both and completely agree with this. Seems like my BCM is easier to clean as the carbon doesn’t get burned on. The NP3 carriers are supposed to be better at this than the Nib. I would say FireClean is more of an answer (it really makes clean up much faster) for you than a new BCG, although their bottles suck.
I didn’t know why until someone posted a super-magnified image of NiB compared to other finishes. It’s much more rough/porous.
Np3/ Ni-ptfe is better on paper. It also has a better track record from what I’ve seen online as far as durability, but that may just be the execution of it, and not the coating itself. Hard to say for sure. I would buy Np3 1st, then phosphate 2nd, before nib. This is in relation to bolts, how much transfers to carriers, I don’t know.
All that said, don’t sacrifice base part quality for coating. Sionics has a good rep and provides both. I’d look hard at them if I was buying a bcg right now.
Even though I think the proper process is a pain, I keep going back to hard chrome for a first for many parts as other coatings tend to fall short in too many areas.
Can NP3 be applied over regular phosphate coated BCG parts, are Sionics BCGs first phosphated?
I have been looking into this topic lately and man there are a lot of options: Nitrocarburization, Hard chrome, NiB, NP3, Ionbond Diamondblack. Then you have MSTN customs applying Ionbond to YoungManufacturing hard chrome bolt carriers!
You have mentioned hard chrome before. Would you mind enumerating the shortcomings of these other coatings/treatments?
I had a complete hunting gun NP3. It was applied and worked perfect. Great process.
I just received 2 carriers from Sionics, and they are perfect. NP3 job was perfect. The carrier with NP3 was $65, crazy good deal.
Are they finally getting those thing shipped? 
Yea we can run a few make sure that are good to go. Sionics teaming up with Robar is very good company to keep. Nice way to differentiate their guns. Every little bit matters.
Short answer, no. You wouldn’t want that. Even if you could, it would offer no benefit as the Np3 would completely cover the phosphate.
