review: pictorial review of the WMD NiBX Bolt Carrier Group with hammer

[mvician]

Just received this today. With all the talk about NiB coatings and my infliction with having to try just about everything related to the AR15 I had to give this a try.

WMD Guns is owned/run by former Fail Zero employees. From what I've read they have improved upon what they have learned. The coatings are thicker, and the parts are sized accordingly to allow for the thicker coating of NiB. This is something other companies do not do.

Specs from their website WMD Guns

Drop-In AR-15 BCGs to increase reliability and ease cleaning and maintenance.

That is BOSS!

What's the price on the kit?

 

[mvician]

Was $199 and change plus shipping from Primary Arms.

Thanks for the info. I have looked at this BCG along with BCM, LMT, Young, and the Fail Zero offerings.

I have only one DI upper (LMT with a 20" stainless 6x45 shilen barrel) and I was wanting to go close to top shelf as I could, on the BCG, CH, and FH.

I would definitely like to hear some first hand experience with the NiBX BCG.

I think I saw one for sale on AR15.com for $215.00 shipped? So the Primary Arms is the cheapest so far, that I have seen. Cool.

Hi Alan........cool to see you signed up on "The BOX".

I haven't had a chance to go shoot mine yet, but everything I've read about the NiB coating is good. Other companies just take a normal carrier and coat it. WMD has them made to their spec so that they can give it a heavier coating and bringing it back to normal spec size.

I've got a few hundred rounds of dirty nasty Wolf ammo that I'm gonna use on this setup and not oil it and see how easy it is to clean

Ever get to try this out? I have a chance to pick up wmd bcgs for $160 and trying to figure out if they're worth it.

Yep, runs like a champ and cleans up with just a wipe down. Only took a toothbrush to get the carbon off of the bolt tail.

If you can get one for that price - get it

Hmm, good to know. Now, is it worth an extra twenty bucks for the hammer in your opinion($180)?

I did notice an improvement in the trigger pull because of the coating. And there is a smoother feel when when charging the rifle as the carrier rides back over the hammer.
