Ionbond/FailZero Comparison

[YammyMonkey]

I've seen a bunch of technical-ish comparisons of the coatings, but has anyone run a no lube high volume function test ala the FZ tests on a BCM Ionbond BCG?

In some of the tech info I found the friction coefficient for Ionbond was .02-.10 & the EXO was listed at .08-.20. Will there be any practical difference between the two?

Application will be an 11.5" suppressed rifle.

It's still going to get dirty fairly quickly, and require lube (yes, the EXO will still run better after a couple mags with lube), so either would work, or going without. Of those the FZ coated stuff is probably the most attractive, but suppressed SBR's inherently need lubrication faster than other setups.

If you're planning on using it with a DI system, just remember that if there's one category where gas piston ARs truly shine, it's with suppressed SBRs (per Larry Vickers). That was the genesis of the HK416.

If you look at LWRC, POF, HK, etc, most of them are using some variation of a plated finish. I think you'd find the Fail Zero much easier to clean, which is very important with a suppressed SBR. Also, if you're firing a suppressed DI SBR, the bolt and carrier will be 8 to 10 times dirtier than they would be without a suppressor. See the pic below. The bolt and carrier were spotless before shooting the 45 rounds, yet wiped off with a paper towel.
