    I am curious how they work in this application. Do you have any input, or does anyone else, who has tried them in a regular mil-spec chrome-lined carrier? Since the rings compress, dimensional variance from the Ionbond isn't likely to matter, as minor as it is.

    Ideally, I would like to mic a new regular stainless ring, and then mic a new Ionbond ring, find 2 that mic the same, and install them on the same bolt and then mic them later to see if the Ionbond did cut wear, any. To that end, which ring takes the most wear, typically, buffer-tube side, or barrel side? Middle? I would like to "disadvantage" the Ionbond ring so as to make the results all the more meaningful if it wears the least.

    I have no experience with them. I use standard ones and McFarland rings.

    Thank-you. I have read all of Spike's propaganda, and the concept actually seems to have merit if extended service intervals are the goal. I guess I'll just have to put the rubber to the road myself, on this one.

    Have the McFarland's provided any increase in reliability for you?

    I don't know because none of my AR's has ever been unreliable. Having said that I haven't replaced them since they were installed. One set has been through at least 10K rounds.

    I tried a McFarland ring one time in a DD BCG. It went from being problem free to various FTF or FTE around 50% of the time. I removed the McFarland ring, put the stock rings back on and the malfunctions ceased. The gun was well lubed with Frog Lube at the time. As I recall ammo was XM855.

    Funny, same exact thing with my Noveske. I never thought much of it though.

    I've had an issue w/one McFarland that only had a couple hundred rounds on it-rings were too small. Caused lock back issues w/weak ammo and failed the gas ring test. Besides that I've never had a problem and still use them.

    I've only tried the one. I noticed as soon as I installed it that the bolt became MUCH harder to slide inside the bolt carrier. Without exaggerating I'd say it took at least 5x the force to slide the bolt inside the BC with the McFarland ring vs the stock gas rings. The malfunctions I had with it were failure to extract (short stroking) or failure to feed. After about two magazines of that nonsense I gave up on it and put the stock gas rings back in. Not a problem since. Next time I want to run some malfunction drills I might put the McFarland back in.

    Every McF gas ring I've put in (minus the one problem child) is stiff when placing the bolt back in the carrier and the first several hand cycles but loosen up quickly.

    I think the issue may be the large variance in dimensions of similar product on the market.
