Sorry, phone auto correct messed up title. What is the "best" NiB BCG and where can I get it? Just got a new Colt LE6920MP-B I want to put it in.

The Colt bolt and carrier in your LE6920 will serve you well.
As the others said, colt BCGs are good to go.
But to answer your question, BCM would probably be the best to get if you are dead set an another one (or a back-up)
PS, I dig your SN
Just polish the bearing surfaces of the colt bcg. This will feel nearly as slick as an nib bcg and not cost you a dime.
Just search for bcg polishing.

Look her for the AIM bcg.
Throw the money at ammo or good glass, things you will see a benefit from.
Just for the record, there is a growing contingent of shooters on this board who have had good experiences with phosphated bcg's that have been polished....and I'm one of them.
Necessary? No. But it accomplishes the OP's goal of friction reduction while still absorbing lubricant and not costing anything other than a felt dremel bit and some elbow grease.

Yeah just the polishing by itself doesn't do much but combined with some other parts and methods it helps smooth out the action quite a bit. Its just a piece of the puzzle.

I agree that NiB isn't necessary, but if you are looking for one the WMD offerings are IMO the best available.
Good advice, all around.
I vote for Rainier Arms NiB since it carries a lifetime warranty. But if you really must have a coated carrier, better to get NP3 or Microslick (if cost is an issue). Less risk of clearance issues than NiB, and Microslick is as cheap as $25 to coat a BCG. For that, it's not worth my time and elbow grease to polish the sliding surfaces.
I thought the advantage of a NiB BCG was that you got to spend less time cleaning carbon off of it. I never bought into improved functioning or reliability or "smoothness" claims. I thought NiB was a one trick pony: to ease the cleaning effort/time pure and simple.
Could someone post a pic of one of these home-polished BCG's please? Maybe a procedure? I'm interested. Thanks.
Lower carrier has been polished. If you'll notice the shiny area that rides inside the upper is the only area that requires it.

I used 400 or 600 grit sandpaper. Apologies for the oversized pics.

Thanks, Jax. This confirmed what I had pictured in my mind.
I like the Wilson Combat NP3 coated BCGs
I think they run smooth and require less line and clean up easier.
I never have a problem cleaning my phosphate BCGs. I lube them often, with slip 2000 grease, after every few hundred shots, and the carbon wipes right off. I do tend to clean my carbeens lots though. Every thousand rounds or so... Mostly to check parts etc for wear/damage.Quote:

Thanks for all the replies, guys. I'm aware the BCG that came with the Colt is just fine and there's no "need" for an NiB, but I wanted something that might be a bit easier to clean, and they look good. I think I'll just stick with what I have for now and maybe consider it later.
The M-4/M-16 is not the delicate flower most have been lead to believe. You can shoot several thousand rounds without cleaning, as I often do, as much as 4K+ rounds fired (with a couple of carbine courses a year thrown in) with just adding lube. When I do decide to clean, the BCG is hosed down with a quality CLP, wiped down, then another coat after. The innards are wiped down, with a few patches down the barrel, if that. it's a 10 min affair.
I think that's a common misconception mostly derived from FTE incidents from earlier models of the M16 dating back to the 60's before the A2. The M4 and M16A4 models today are far more reliable with far less such incidents. I have a buddy who was in the Marines for four years, much of it in the Middle East, and he told me stories of how ridiculously dirty his M16A4 got, but never jammed.
One of the 'advantages' many companies claim with these fancy new coatings is the ease at which the BCGs can be cleaned. Realistically a few sprays of brake cleaner is all that is needed. Relube and done. Kinda negates the purpose of it. So many people think the AR requires meticulous cleaning. Wrong. Just keep it wet. If you look at the pic of the BCM BCG I posted earlier it is absolutely caked in carbon. But it is also caked in FrogLube so stills runs perfect.

OP: I corrected the title of your thread.
That will be $15, please. :dirol:
Im using an Ice Arms NiB BCG. Its a lot smoother when charging, no more gritty feeling, or smell of matches. Gun cycles smoother as well
NiB is certainly beneficial in some niches (those niches being auppressed/SBR/FA/combination thereof). I see no worthwhile utility in a semi-auto 16" barreled carbine. Aspirational product for most IMO.
Colt BCG, good. Unnecessarily spending money, bad. 'Nuff said.
Sent off a BCM bcg to WMD guns for coating. Makes cleanup easier. That's worth it for me. Don't worry about which
company has the best nickel boron coated bcg. Just find a company that makes a quality bcg and then send it to be
coated. Best of both worlds.
You'd be surprised with a proper lube like FireClean how much of a difference in felt 'slickness' is made. I used up almost all my FireClean during a class lubing everyone elses BCGs :/
