Hope it gets better.
After researching nickel boron BCGs, I decided to go with this one. The finish is perfect. No machining marks and smooth. Cleaned BCG and applied a light coat of oil. Fired 20 rounds last night and didn't clean it. Tonight, the caming action of the bolt in the carrier was very stiff. Noticably harder to charge the rifle. Disassembled, cleaned, and lubed bolt and it works better. I was firing factory new Hornaday ammo. Hope it gets better than this.

Amazing BCG super finish and quality
by chris smith
Awesome bcg! One of my favorites!
by Michael Hartmann
Best I've used in a while, easy to clean however once used the finish is still bright but darker and took on a gold color instead of the silver.

Compared the NIB-X to a bunch of other Nickel boron BCG's for my gas impingement AR and decided on it over the rest. Received it, cleaned it thoroughly and once it was clean it's literally like it's oiled! I still will run it with a light coat of Slip 2000 EWL! UPDATE: Took it to the range last Saturday and ran 60rds through it with no issues. Got home and wasnt impressed with how it cleaned up! My P.O.F rifle has a NP3 coated BCG and is a true wipe off BCG. IT is a piston rifle so it runs cleaner and cooler but was a little disappointed in the companies claim to simply wipe off.

Couldn't be more pleased! The finish is extremely smooth. Carbon fouling brushes off. This product is a must have item for DGI rifle!
WMD BCG Sale

Excellent, Outstanding! Both the product and Primary Arms are superb!
Very nice BCG!!
by Chris Anderson
First off, I want to thank Primary Arms for their superb customer service. They also process and ship orders faster than any other company I know of. Okay, so now to the WMD BCG. This is the first NiB-X BCG I have ever owned, so I cannot compare this to any other. I was amazed at how slick it feels right out of the bag. I also examined it for fit and finish. I did not notice any burrs or sharp edges anywhere. The machining is excellent and I can see that their quality control is on par with higher end BCGs that I've owned in the past. As of writing this, I have put 300+ rounds without issues. I purchased the "full-auto" version and it works and runs flawlessly through my Spike's Enhanced AR15. I would have to give this purchase 5 stars for both product and PA's fast shipping. If your thinking of purchasing this, don't hesitate.

Great product and service
by Larry Pugh
Great product the best service.This is my second WMD Nib-X bolt carrier. I wish I had them in all my AR's. The fit and function is perfect and the Nib-X finish lives up to its claims.
nickel boron BCG
by Dante Evangelista
high quality product nice nickel boron finish and delivery super fast.very satisfied with the purchased.
i have other wmd products and this one has the same quality i expected from wmd. great product very well made
Finish Looks Great
I haven't had a chance yet to take this thing out to the range since the rifle it's going in is still being built, but the fit and finish are top notch. Straight out of the package the coating felt slick and lubricated. I tried wiping it down to see if it had some lubricant on it, but the slickness is just the finish. Pretty sure I'm going to run it with a little lube even though it says it can be run without any. Hoping it cleans up as easy as other reviews I've read says it does.

I'll have to admit.. It looks WAYYY better than my FailZero BCG.. I also like the WMD logo on the side..
I'm using this on a Del-Ton 5.56 that I shoot a lot. I call this one my tactical weapon, in this case not your traditional definition, I use it target plunking and, more importantly, with my Slide Fire. Anyone that knows about this nice add, I go through a lot of clips every time I go out on my property. After 500 rounds, basically clean and functioning great. 1000 rounds without cleaning, wiped right off and looked brand new. Outstanding add for me!
so far so good
by kervin hilpipre
initial impressions are good. very smooth to the touch. cant comment on clean up or durability yet. everything is real slick. if i had one thing to complain about is that the bcg is 10 dollars cheaper from when i bought it 12 days ago! so buy up while the price is low.
by Abel Duque
It came engraved, not a burr on this thing, wasn't expecting less anyways. As always primary arms delivering top notch.
Looks like a great BCG, but have not used it yet. Seems to be higher quality than some others I have used.
Great Products, Prices,Customer Service
by Stephen Adams
Most reviews I read are more about the great customer service than the product. A company is only as good as the people they have working for them. I know PA understands this and will be successful for a long time. I will be a lifetime customer. Thank you, God Bless
outstanding bolt, outstanding service; as usual.
by Jerry Cummings
Ordered this BIG when it was on sale. Received it a couple of days later. This is exactly the type of service I expect and get from Primary Arms.

Excellent product-superior service
The BCG is very well crafted. I expect good service and longevity over time. The real story here is PA's superior customer service. The order was processed literally within one hour of my placing it and delivery was extremely fast. I continue to be amazed at PA's service.
WMD M16 FA NIB-X BCG
by Landon Ernst
This BCG is Flawless. It even looked a tad bit better than the Spike's NIB BCG I purchased. Sold the Spike's and keeping the 2 of these I got.
