WMD NiB-X AR-15/M16 Bolt Carrier Group - With Hammer
Out of Stock
Ratings & Reviews
by Garrett Moore
Admittedly, I purchased this BCG because it's the only one I could find in stock, worrying that the Nickle Boron coating was a bit of a gimmick. However, I am beyond pleased with it. The bolt feels perfectly oiled when it is bone dry. I went ahead and oiled it anyway, basically using the coating as insurance. The bolt functioned flawlessly. At the end of the day, I was able to wipe it clean with a paper towel and it looked brand new. I would definitely purchase again. Thanks PA!
As always top rate service from Primary Arms. Best BCG you can get for the money.

by Clifford Jr.Mercier
Flawless machine work. Dropped in right out of the package. 200rounds later,no FTF or FTE. Other than slight discoloration, wipes clean with a rag and continues to rock and roll!!!!

Good workmanship, and very slick finish.
by Brandon Huynh
Great product, haven't tested it yet but it seems to be good. It smooth to the touch as if it already has some lubrication on it, but it doesnt.
Just a BCG
by Robert White
I bought a WMD NiB ar-15 BCG with hammer from here because these guys had the lowest price. ordering was easy, and cut to the chase. My package arrived on time and my product was exactly as it was supposed to be: shiny and brand new. I won't hesitate to do further business with PA.

Great Service and Product
by Lee Roberts
I needed the BCG for a custom AR upper being built. The product was as advertised.The item was shipped same day the order was placed which was great. I added Primary Arms to my favorites list
so far somewhat ok
by peter gonzales
installed it today and went shooting this afternoon. they say no lubricant needed....my first 2 rounds did not load correctly. a few times after I had to use the assist to the bold. took it apart and used oil inside and out....seemed to work fine for a while. finally after about 200 rounds it started to loosen up. no further issues as of yet. looks great cleans easily. I will be shooting again within the next few days. if it malfunctions again I will take advantage of the 30 money back guarantee.
Nickle Boron is slick
It is smoother operating than a standard bolt carrier. You can tell the difference. I got the WMD because it came with a Nickle Boron hammer also. Good price and great service from Primary Arms as always.
by Steve Wash

Ordered WMD nib-x bolt carrier. Product was in stock. Price was spot on. Communication was great. Shipping was fast. Item as described and packaged well. Will shop PA again.
The best I have ever used.
by Robert Hutto
Purchased June 2014.300-400 rounds fired every session. No failures,just a little darkening of the finish due to mag dumps,half of my ammo is spent this way.Very pleased, see no reason to try the new Relia-Bolt everyone is talking about, I'm sure if the had tried this BCG they would never mention the above. Now I have said this let me knock on wood
WMD makes one fine bolt carrier
Put this BCG into my Spikes Tactical upper and has run flawlessly for 1,000 rounds so far with minimal lube. The NiB coating is not as shiny or "clean looking" as chrome. It has a darker tint to it and "looks a little messy" even when perfectly clean. I already knew this before buying it so could care less about appearance, as long as it functions well. Primary Arms has the best price for a NiB BCG WITH NiB Hammer.
Beautiful. Bring on the excess carbon and zombies!
Smoother than (the liar) president Obama in 2008.

The BCG has a very smooth Nickle Boron plated surface.Despite it having high lubricity due to the NiB exterior, a little oiling still assisted with the initial wear-in with my barrel.Bolt Carrier Group cleanup is a snap.
Hard to say since I haven't gotten to use it yet
the build quality seems great, except the cam pin was way too tight. I sent it back to WMD and they're sending out a replacement. Great customer service, they actually answered the phone both times and talked the problem out with me. I'm sure the replacement will come back perfect as I hear pretty much nothing but good things about this company. If so, I'll raise my rating to 5 stars.
