What do they do and what are the advantages?

Slicker than parkerizing and easier to clean.

3

Is it really worth all the extra money?

4

IMO, no, for that price I would get chrome, I have an ionbonded barrel, and it is not that much slicker than parked.
I would be more interested in an ionbonded upper, which is not saying much.

5

Well the ‘slicker’ the metal to metal contacts the better but you probably won’t notice a difference for 95% of people.

Its certainly not going to hurt anything…

Here is my BCM ion bond BCG after approx 400-500 rds:

Ionbond is also porous so it absorbs oil and slowly releases it when it needs too, and if it has the full DLC treatment than it may have the Hard Chrome base coating as well.

7

more porous than parkerizing?

I would be more interested in reasonably priced ion-bonded bolts than whole bcgs.

8

I think so, comparing my parkerized N4 barrel which would dry out in a week sitting in my safe to my old Ionbonded 1911 that would stay wet for weeks there is no comparison.

9

It’s hard to clean now?

10

I hypothesize that the parked is more porous, and absorbing the oil. Hard to say, I dont use any oil that drys up, but maybe you do, hard to say with so little info.

11

My hard chrome bcgs are much easier to clean than parked, and my motorcycle is faster than my car.
But i am not saying that the parked are hard to clean, nor am i saying my car is slow…

So I am not sure what you are getting at

12

Weapon Shield CLP?

My old Ionbonded TRS was the slickest handgun I’ve ever felt, I sure miss it sometimes lol.

edit: and nothing stuck to the Ionbond so it was easy to wipe down as opposed to scrubbing.

13

One more tidbit… Ionbonding is just a process and not all are equal.

14

No…its just easier with ionbond.

I think the point is…is that the surface is slicker, and since the BCG is the only moving part during firing aside from the buffer it makes sense to have it be as “slick as possible”. I also believe ionbond surface is harder, and there was very little wear to the BCG after firing.

The question of ionbond is is worth the extra money? I would not buy them for every gun I own but for a main gun its something Id like to have. Its not going to decrease the chance of a bolt failure or anything but it does have its merits.

15

For those of you guys interested BCM has the Ionbond BCG’s back in stock…

Thanks for the heads up. I just ordered one for my BCM4.:slight_smile:

BCM,s Ion Bond BCGs - Yes their worth the money

Ionbond is a company. There product (the one we’re discussing) is Amorphous Plasma Assisted Tungsten Diamond Like Carbon or W DLC. I know because I’ve worked closely with them and the National Sales Director is a close friend of mine. Underneath the WDLC is 3 microns of electroless Nickel.

If any is interested I have tons of info (much of it correct) at www.pistolsmith.com under Finishes from some time ago.

It’s great to have on a 1911. G34shooter, you should have called me. I would have gladly relieved you of your TRS. Dammit, I wish you still had it (and wanted to get rid of it). Oh well… :frowning:

19

It actually sold pretty fast and I got what I asked for it lol

I do miss it as it was a highly shootable work of art :o

20

I saw that on BCM’s website the other day and was a fairly interesting read. I may have to get one just for shits and giggles.
