I tried mine out this past weekend.
Tula ammo feeding from a metal XCR mag would sometimes run into the feed ramp without chambering. Other mags worked fine. Federal independence worked fine. I may have run a handful of norc, and it worked fine
Accuracy...eh... considering I have DD irons on it, my eyes were probably as much at fault as the rifle.
Not much for ejector marks on the revceiver, but I do run a 3Bucc brass catcher attached to the handguard - the pic rail on the receiver is out of spec on the large side - my brass catcher mount would not fit it and, in fact broke when I persuaded it.
Gun ran fine with the Triggertech in it. No malfunctions other than the few feed errors with the Tula. No odd primer marks that I could tell.
I had the gubbins lubed up sloppy with wheel bearing grease, and noticed nothing unexpected for wear/markings afterwards.
It's probably way over gassed, by the briskness of operation.
As my designated blaster, it's probably going to see nothing but surplus ammo until I run out of same. I don't plan to spend time tuning reloads for it.
It's a rifle I bought for political reasons more than any other.
Good on Wolverine for forcing the other guy to blink. I'm proud to support that.
