"Call me a happy Guinea Pig"
Glad both you & the test media made it through with flying colors! Will likely be a while before the average accuracy for several samples will be known, but if most are like yours, that's a major win.
I didn't know, until you mentioned it, that they have an adjustable gas block. So I watched the vid this time & saw it, a good option IMO. Had a FAL years ago & liked the adjustable gas on it.
Dang it, now I want one. Thanks so much for the report.
