View Full Version : FailZero BCG: Review
I've been running a Fail-Zero BCG in my 11.5" BCM SBR. There has never been a lick of lube put on this firearm.
For the first 836 rounds, ~half suppressed and some full-auto & suppressed, I didn't experience any failures. (I did clean at 836 rounds but did not lube because the Marine Corps in me was screaming)
I did replace the action spring with a Tubb's flatwire CS spring and replaced the H buffer with an H2. Still cycles everything from M193 to Wolf 55gr. My SBR is seriously running some gas down the works :D
As of today I have 2,546 rounds through the rifle and it's been 1,710 rounds since it was cleaned (not even a wipe-down). No failures due to lack of lubrication (I've had two stuck cases /w Wolf ammo at below 30F. Not related to the BCG at all).
The inside looks nasty but still no problems.
Of course, pictures:
Outside: Note the discoloration by the ejection port from escaping gas (and yes, the BCG was originally silver-colored)

Bolt itself, pretty filthy

FCG, lots of grit all over it

Gas tube and chamber, the nastiest of all
http://img.photobucket.com/albums/v11/DavePAL84/projects/chamber.jpg
Lots of white schmaltz wear the upper meets the lower at the rear, from the can I imagine. Don't have a good picture right now. I never expected this rifle to run this long without any cleaning or lubrication. Gonna shot another 290 rounds on Friday to make it an even 2k before I clean anything--with my luck it'll fail at 1,999 rounds :lol:
Regardless, after this I'm gonna clean every 1k rounds just for maintenance's sake.
Nice post. I've been thinking about buying a back-up. Its good to see that number of rounds with no cleaning. Bad ass rig you got there.
Would you say that you are completely converted?
Try running a standard BCG dry, and suppressed for comparison's sake.

I think the real advantage of the FZ comes into play with suppressed or FA shorties--Nothing eats lubricant quite like a suppressor. I will say that I am tempted to use a FZ BCG in my new LMT built but I'm not quite sure as it's a 16" and won't be run suppressed very often.
I have a new Noveske BCG and a new Ion-Bonded BCM BCG, but after seeing what you've done here I may have to spring for a FZ for my 6933 upper with M4-2000. Thanks for the report! :)
I'm convinced that suppressed ammo will increase the amount of fouling 6X on a DI SBR. Fail Zero, chrome, Ion Bond, etc is definitely the way to go.
that answers that question. yes i will pick one up. how far you gonna go before cleaning? 5k 10k ? and then do post pics of the clean up. i dont envy that job
Okay, so I had and FTE today--at 2006 rounds! Cause'd by a short-stroke. I made it over the magic number and cleanup was a real bitch. Here's what she looked like after 2035 rounds with no cleaning or lubrication (I *did* clean her today but did not lube).

It should be noted that 250 of the last 325 rounds were shot suppressed. So, 2,035 rounds since last maintenance and 2,871 total.
I highly recommend this BCG.
SOLD. excellent review my friend. and 2000 rds sans lube is amazing. now lube the shit out of it and keep shooting with lube till it fails again.
and you forgot clean up pics.
Just a random thought I have while reading your review: About how much time would it take you to return that rifle to "like new" clean... inside and out? I'm looking at your pictures and thinking hours, not minutes!
Is the DPMS special coated BCG's similar or is that FZ a very unique and special coating?
DPMS shows 3 or 4 unique coated complete BCG's on thier site ranging from $130 to $185.
where did you pick this up from and if you dont mind what did you pay for it?

You should probably clean some of that carbon build-up off. I can only imagine it hinders any lubrication provided by the finish they apply to their BCGs.

I cleaned it last night. I'm not going to be running it 2k rounds straight from this point on. I just wanted to see how long it would go.

Don't bother with the Brownell's link. The FZ webpage has em' listed for $250 right now.

The BCG cleaned up easier but I didn't just wipe down that amount of stuff off with a rag.
The upper, of course, was far more of a pain in the ass. I normally wouldn't have near the amount of carbon during a routine cleaning because I let it go for so long.
Great review there!

Excellent review. I'm more a fan of advanced metal treatments on firearms the more experience I gain with them (been wringing out IONBond Tungsten DLC and Melonite on 1911s for several years), but especially inside the AR15 platform. FailZero's UCT seems to be rising, if partly because they're applying themselves to the market and acquiring new industry partners to utilize their treatment. I'll have to try the FZ BCG in a rifle next to the IONBond one.
Does anyone know how the FZ BCG works compared to a BCG that you would send to Robar for an NP3 finish??

Does anyone know how the FZ BCG works compared to a BCG that you would send to Robar for an NP3 finish??i've read that Robar's np3 finish is nickel-based(nickel treated with teflon). failzero is a subsidiary of UTC Arms(UTC Coatings http://www.uctcoatings.com/%5Cpress.asp?rls_id=14& ). Their coating, EXO, is also a nickel-based finish(nickel-boron http://www.uctcoatings.com/subpages/technology.asp ). I have no idea which is the "better" of the two. Maybe you can google from here.

saw that but the combined shipping saves me a little extra. did you get the hammer too or just the bolt? is there any benifit to the hammer? and did it come with a firing pin.
was hoping to see after pics too... would like to see how it faired with wear...
I'll take some 'after' pics this afternoon

Looks the same as the day I got it. One thing you may notice is that the coating doesn't look exactly like hard chrome (you can see some black here and there). It came like that. I'm told it's because of the Boron but maybe someone from FZ could confirm.
Chamber area (still a little bit of gunk, need to hit that up again to ensure a full-reset)

Came with a firing pin. It also came with a hammer but I did not use it. FZ says it will improve reliability but I'm not gonna argue with the results I got.
What did you use to clean your bore? What did you have to use on the BCG to get it clean?
Cleaned the bore with non-chlorinated brake cleaner and Hoppes #9. Cleaned the BCG with a brush, rag, and Hoppes #9.

i really want to give this a try
That sounds like a pretty impressive product.
I wonder how long a non-suppressed 16" carbine could go between cleanings when using the FZ BCG.

Considering 16 inch guns can go a REALLY long time without cleaning as is, i can only imagine.
Im up to 2.3k rounds since my last cleaning. Ive only added lube.

Oh you can get an AR running a long long time by just adding lubricant...
I notice that the FZ "AR-15 Basic Kit 009-FZAR15-01" includes a treated BCG and a treated hammer. Are you using their hammer, too, or just the BCG?
It also came with a hammer but I did not use it. FZ says it will improve reliability but I'm not gonna argue with the results I got. :cool:

Ooops, missed that one. Thanks!
I worked WITH not FOR Ionbond for a bit having 1911s coated so I know quite a bit about plasma assisted amorphous W DLC.
In my OPINION, I think W DLC would be the better coating. It's much harder and has a very low coefficient of friction. I'm not sure which has a lower coefficient of friction but I do know that the W DLC will adhere better (last longer). It has a thin coating of electroless Nickel underneath to provide it better corrosion resistance.
The "ultimate" would be a Tenifered/Salt Bath Nitrocarburized bolt assembly and then have W DLC applied using the best steel alloys, of course.
My two cents.
P.S.
Nice report!

Good God man. Overkill much? :eek:
My understanding is the biggest criticism of the nitrocarburizing process is the comparatively high heat the surface is subjected to. The carrier itself is probably fine being subjected to it, but I'm not sure about the bolt (meaning, not enough information so I don't know). Might it be better to just nitrocarburize the carrier and use DLC on the bolt, or would it be more cost effective to just double-up?
I also want to see this type of BCG run in a 16" middy. We'd have to do a couple fund-raisers for ammo. :D

Yes, I do like overkill perhaps too much. This I will readily admit. You got me. :p
It can be applied to the bolt with no issues. An appropriate process (time, temp, duration) must be looked into due to the relatively thin lugs but there is more material on the lugs of an AR bolt than on, say, a 1911 frame. The thin coating that results would not/should not effect the core hardness if done properly so brittle fractures should not be expected.
Just out of curiousity --
I assume that's the "AR15" version of the kit (as opposed to the M4/M16 version)?
Is the carrier semi or FA version? (sorry, can't tell from the pics).
Thanks.
I see. Would either of these processes be wasted on, say, the JP high performance bolt?

how does not cleaning affect the accuracy? also if I dont have the factory bcg how often should I lube?
So how did your inner receiver wear? Im sure the bolt would hold up but I would like to see the receiver as well. Any accelerated wear on the aluminum?
We have FZ BCG's at $250 as well.

Accuracy is all gonna depend on your specific barrel and a myriad of other factors aside from solely cleaning. As far as lube for a regular BCG, follow Larry Vicker's advice:

Yeah but you cant see any detail. Thats why I asked you, how do you feel the upper held up?

Wear patterns so far appear to be normal (no worse than any of my other AR's).
That said, this was actually one of my thoughts when doing this test. However, to really find out I'd have to compare it to another SBR with a similar round count. That I do not have on hand.
so i guess the bottom line is
is it worth the extra hundred bucks?

Thank you, that was my first thought as well when I saw these. I was thinking it doesnt really matter if the bolt lasts forever if it just wears the receiver out faster. I dont think it would have been the case but you did the work to see. The results look pretty good...:D

Electroless Nickel Teflon is between 600-800 Knoop hardness. UCT's EXO coating (NiB) is 1300-1400 Knoop (~78 Rc), so about twice as hard and wear resistant as EN Teflon. The lubricity in the NiB material is inherent in the material and not reliant on an interspersed, codeposited material such as teflon. EN Teflon is designed to release teflon, then wear the nickel, then release teflon, etc. The wear life of the EXO coating is much extended over that of EN based technologies. UCT offers EN teflon for less severe and other applications, as well as regular EN coatings. Hope this helps.

I have a question that I have been curious about. Have you guys done any testing with the full auto upper kit in combination with POF's roller pin cam? It is my understanding that most of the friction in the AR comes from the BC riding on the rails in the upper, the BC resetting the hammer and the bolt un/locking in the BE.
At the same time, the BCG has to overcome the pressure of stripping a round from the magazine. Because the bolt "floats" in the carrier, it causes the cam pin to turn and rub against the upper receiver. With a lot of fouling, couldn't this add more friction in the equation? I think that with the POF CP instead of digging into the receiver, it would roll making it easier to strip a round from the magazine.
Could you potentially get more use before cleaning out of this product if the POF cam pin is included? Would you also get better performance if you had the BE coated as well?

I'm very interested in trying a Fail Zero BCG in my new BCM upper.
This upper will eat nothing but cheap Russian / Hornady steel cased practice ammo, with minimum maintenance. :D , suppressed a great deal of the time.
I've been running a Fail-Zero BCG in my 11.5" BCM SBR. There has never been a lick of lube put on this firearm.
For the first 836 rounds, ~half suppressed and some full-auto & suppressed, I didn't experience any failures. (I did clean at 836 rounds but did not lube because the Marine Corps in me was screaming)
That appears to be an AR15 receiver. How did you run it auto, a 'drop-in'? What can?
Does anyone have a current picture of the carrier key staking on the Fail Zero bolt carrier?
I found this picture through a google search, but it's over a year old. I'm hoping they're doing a better job now.

I can't speak for FZ's BCGs, but I have 4 of the Spike's NiB BCG's that FZ coated and the staking on them is stellar...

Is there a difference in the coating between the Spike's Tactical Nickel Boron BCG, and the Fail Zero BCG
I read that FZ coats the BCG's for Spikes, but is there a difference in that coating.
The color looks to be different between the two from what I see
Which one is better and why?
Early on, FZ had some cosmetic "issues." Spikes has said they basically have higher standards, cosmetically, than FZ. So, while I have not compared the two (I only own the Spikes) I think Spikes gets the "cherry picked" ones.

There shouldn't be any difference in the coating. The two companies may source the bolts and carriers from different sources though, and may use different testing methods.

Didn't see this question until just now. Upper was put on an a registered M16 lower for the FA shooting, same buffer and Tubb's CS action spring (it mostly lives on my SBR lower) Suppressor was one of my Gemtech Halos. Same one I used for the, 'cooking bacon with a suppressor' video.
A BCM with a lot more rounds through it called "Filthy 14" and the BCG is a lot cheaper. Not sure I see the benefit here other than not having it lube it. But lube is cheap and accessible.

It's is a niche product (which also works well for 'normal' operation), mostly for SBR/suppressed/FA or some combination thereof. Nothing eats lube quite like a suppressor. My 16" guns still run regular M16 carriers.

The CEO of Spike's Tactical told me Fail Zero has a big bench mounted MOACKS tool to stake their carriers and they do a good job with it. It's not rocket science, all you have to do is displace enough metal to hold the screws in place. Anything more is unnecessary.

It's the same thing, and they both source their bolt carrier groups from AO Precision in Daytona Beach, FL who is a US Military contractor. It's personal preference of whose logo you want.
Exactly right, the idea is to apply pressure via the stake to the screw.
too much pressure deforms the gas key and the screw, making the screws difficult to remove if the gas key is damaged by dropping to a hard surface.

I agree that nitrocabunizing is the way to go but still not as strong or as lubricating as the nickel boron coating of FZ. I have both and I prefer the fail zero coating over the nitrided bcg as it is much smoother and easier to clean. With that said however I will not put a barrel on a build of mine that is not nitrided as it does offer a significant advantage to steel products if done properly. With that said the other advantage that FZ offers that you cannot get out of nitrocarbunizing is that the coating/plating with their process can be added to aluminum as well hence the coated upper receivers which I also recommend as it makes a night and day difference to cleaning your DI weapon system.
Entire uppers coated in this? I know this thread has been untouched since April but what could this process offer functionally other than just a quick wipe down? Are coated receivers planned or was this just some proposed idea?
please go to the WMD Guns Forum on M4Carbine for Nickel Boron firearm stuff. Coating the uppers and charging handles have benefits. It is not absolutely necessary to run with an NiB-X BCG but it smooths out the action and prevents wear in extreme use.
We will release coated uppers at the SHOT show and coated lowers shortly after.

Soooo, A few years later... :)
All the folks that bought Fail Zero BCGs, do you still have them? How are they doing??? Solid Product or Snake Oil???
I've put a few thousand, less than 10 through a larue predatar with a fail zero BCG and haven't had a single issue. Fail zero is good to go

I have replaced the bolt, not due to failure but for reasons of proactive maintenance. Carrier still there, albeit stained from using Hoppes (which interacts poorly with nickel). I would buy another. There are a lot of good coating options now
I had a complete BCG of theirs in my 11.5" AR.
When I first got it, had some failures to extract, but it was a quick and easy fix. I just replaced the extractor spring with BCM's, and it ran perfectly afterwards. I sold it purely due to the fact that I didn't like the shinyness of the carrier sticking out the side. I still have a FailZero bolt in it though, riding in a BCM carrier. Works well. No issues.

I have had a complete BCG in one of my AR's for 2 1/2 years now, and it works fine. Zero issues.
