Let me recap for the sake of open disclosure. I have run 750 rounds through my AR with just the initial lubing (with a q-tip) I showed in the first video. Of the 750 rounds I had three failures due to improper ammo that I shot without thinking about it not being tuned to the gun. It was an ammo failure, not a lube failure.
Since the last light load failure, without cleaning or lubing, I put 330 M193 rounds through it to bring the total number of rounds through the gun to 750. I could kick myself for introducing the marginal ammo into the test. But be that as it may, with the ammo the gun is tuned for, it was flawless - 747 rounds but with the "benefit" of the nastiness of the three rounds that failed.
Oh, the gun still hasn't been cleaned, but I am seeing some signs that the carrier speed is slowing some. But after 750 rounds with no additional cleaning or lubing, one would expect it to eventually fail.
Something I'm struggling with is how did it do this? There are only two possibilities: either FP-10 is a remarkable lube, or an AR will run for hundreds of rounds even dry and dirty. Common knowledge says an AR won't run dry. If that's true, then there's only one other answer - FP-10 is good stuff.
More later - I just got back from the range and it's time to eat!
This is pretty much a wrap-up video bringing the round count to the 750 mark:
