After a year or so of Paul and me bitching about the hit and miss quality of factory BCGs and me doing the Super Duty Line in the interm, Psul took action and contracted with the top manufacturer of Mil Spec BCG components to make his own BCG.

ION BOND BCGS ARE NOW ON THE WEBSITE AND READY TO ORDER.

ALL THE ION BONDED BCG'S ARE 100% HIGH PRESSURE TESTED.


The result is, in my opinion, the best Bolt Carrier Group you can buy. In fact I will no longer offer the M16 version of the Super Duty as long as Paul can keep up with demand.


BRAVO COMPANY MANUFACTURING M16 BOLT CARRIER GROUP


Although this looks like every other BCG on the market it has some very unique features and quality control aspects that make it superior,

Features and QC assurances:

SHOT PEENED AND MPI TESTED BOLT
SHOT PEENED AND MPI TESTED EXTRACTOR
ALL MAJOR COMPONENTS INCLUDING THE GAS KEY ARE ROCKWELL TESTED
EACH BOLT IS TEST FIRED PRIOR TO MPI TESTING.
EXTRA POWER CHROME SILICON EXTRACTOR SPRING
CHROME SILICON EJECTOR SPRING
BLACK BUMPER
PROPERLY SIDE STAKED GAS KEYS SECURED WITH GRADE 8 ALLEN SCREWS
MILSPEC FINISH APPLIED AT BCM
A CRANE "O" RING IS SUPPLIED WITH EACH BCM BCG SHOULD YOU DESIRE TO USE IT


No statistical testing here either. Each bolt is test fired prior to the MPI inspection.

At only $135 each it is a bargain. Better quality than even Colt at a much better price.

M16 only.

Available only thru Bravo Company, Global Tactical/Denny's Guns and G&R.

ION BOND VERSIONS ARE ONLY AVAILABLE AT DENNYSGUNS/GTS

ION BOND BCM M16 BOLT CARRIER GROUPS, A FEW PICS AND SPECS.


The Ion Boned version as the same specs as the standard BCM Bolt carrier groups listed above with the following features:

90 ROCKWELL ION BOND TC4041 ON THE BOLT, EXTRACTOR, BOLT CARRIER, FIRING PIN, CAM PIN AND GAS RINGS.
EACH ION BOND BCG IS HIGH PRESSURE TESTED


BCM ION BONDED TC4041 BCG M16




DISASSEMBLED



CLOSEUP OF THE FRONT SHOWING THE BOLT AND EXCELLENT STAKING



YES, THERE IS SOME BRASS ON THE BOLT FACE IT IS NOT USED, IT IS THE RESULT OF TEST FIRING.



NOTE: THERE ARE ONLY 48 OF THE ION BONDED VERSIONS AVAILABLE AND IT WILL BE A COUPLE OF MONTHS BEFORE WE GET ANOTHER BATCH.

Check one out if you want the best for your AR or M16.

A SHORT ION BOND PRIMER.


Ion Bond is a Tribological coating that bonds to the matrix of the base metal and becomes part of it. It is PVD and PA-CVD technology

It is about 90 rockwell in hardness. Much harder than hard chrome and black in color. It accomplishes several things on the AR BCG.

Reduced coefficent of friction

Increased abrasive wear resistance

antiscuffing?antigalling

high fretting resistance

high pitting resistance

high corrosion and carbon resistance

reduced friction and assisted lubrication

accomidated higher contact pressures

ultraclean surface engineering

ISO 9002 certified.

So, these are different than the regular BCM BCGs that are just MPI'd and not HPT'd first?

Is the ejector spring a CS spring? Not that it matters...

Any chance that these might get an ion bond type coating in the future?


Looks like a GREAT BCG.

Paul might have omitted the HPT in his description. the BCG's are all HPT's first.

My error. Each bolt is test fired only. They are HPT's statistically

Yes, the extractor and ejector springs are CS.

funny you should ask about the Ion Bond. We just got 100 of them back from them. Stay tuned..............

Not a tag.

I have a no name BCG in my favorite AR-15, its not staked or anything just from the gunstore. I always wonder what it is.

If it running good don't worry, I would check the gas key bolts for tightness and then side stake it with a punch just for reliabilities sake.

Buy a MOACKs tool from michiguns.com and have at it. Or just send it to me wrapped in a 100 dollar bill and I'll do it for you

Denny,

I asked you this before, but did you confirm that the ejector spring is CS? They don't mention it on their website and they don't offer a CS ejector spring with their bolt upgrade kit, only the extractor spring.

Yes, the ejector spring is also CS. Paul doesn't put them in the kit as they are too hard to do without the proper fixture.

I picked up a BCM M16 BCG about two months ago, I don't see that these are much different, and I have been very happy with mine! I did a lot of shopping before deciding on the BCM, and am glad I did. Seems to be an excellent value for the $$.

Mine went in my RRA Middy to replace the original, which has since become my spare. The original was also upgraded with Paul's extractor upgrade kit via Denny, and I added a little extra staking to the key for good measure.

I haven't had the chance to run my BCM BCG very much yet, but it will be attending Pat Rodger's Carbine class in Dec.

Pardon my ignorance.

This is for M-16 only so I couldn't use it in an AR-15 build?

Sure, you can run one in an AR15. Most all of mine run M16 BCGs

I will be adding them to the website as soon as Paul gets them back to me. He is test firing them this weekend.

BTW All the BCM Ion Bonded BCGs have been HPT'D

So I presume this comes with a firing pin and all that kit? And what's the deal with the Ion Bond coating, what does that offer (and do you know what the pricing will be)?

Yes, that will beca complete ready to run, drop in BCG.

Ion Bond gives all coated areas a 80 Rockwell hard coat finish, ie. virtually zero wear. It also has great lubricity and holds oil far better than park.

Ion Bond becomes part of the matrix of the base metal and is not a plating or a coating so there are no chipping or peeling issues. Also, unlike hard chrome, there are hydrogen imbrittlement issues.

These are being done just like the test piece I sent my buddy, who training EOD guys in an undisclosed location. After 6000+ rounds the BCG both looked and worked like the day I gave it to him,.

Ion Bond is also a snap to clean as it has a great dis-affinity for carbon. Oh yeah, it is black too so no bling issues if you are being covert,


$195 shipped USPS Priority Mail with confirmation

Denny,
Does the "TC" in TC4041 stand for TriboCote?

I think it stands for tungsten carbide
mrrick  [Member]
10/5/2007 3:04:46 PM
I e-mailed Ionbond and got a reply about that the other day.
they said it is thier tribocoat DLC coating.
they have a tribo coat 40 and a 41.as well as combining them
from looking at tooling coated withthis at the local shop it is a VERY good
one to have especially seeing how it has held up being used in tooling.

Diamond black is Boron carbide (B&C)
tribobond 40 is A-C :H : Me
tribobond 41 is A-C :H : Me+a-c :H
what those are are not listed in thier PDF. but they do say it is a multi-layer
Diamond like Carbon/coating.

nomatter which it is denny is doing he is using a very good coating you won't find
anyplace else.

Are these coming out of Ion Bond's North Carolina Plant? If so, I know their new General manager and he's top notch. Lots of gun coating experience.

Received my Ion Bonded BCM BCG in the mail today. It looks and feels great, I should be taking it to the range next week.

Denny, thanks for the great service and quick shipping!

ETA: Do you know if there's a particular lubricant this coating likes, or one you know will work best?

Holy Crap I got it already! Got the buffer too.
The BCG looks great and now I won't have to worry about the rails of the carrier showing bare metal. I strip everything with brake cleaner after shooting and this should prevent any rust.... ever. I am going to try out my Dfender ring instead of the O ring to see how that works. I never used it, might as well put it in the best carrier now.
Thanks again!

Some guys want the best, others are satisfied with the average.

We build rifles and see the problems more than the casual owner so we have a different perspective.

because you won't find a better one, well built, best selection of parts and the Ionbond coating.

mine still looks unfired, looking closely at the bolt lugs, no wear marking.my std one you can see some.
