I finally got to shoot it farther than 25m this afternoon. It's not exactly a precision rig with the short barrel and 4 MOA Aimpoint, but I didn't have any problems banging the gong at 200m with 5 shots in a row from the bench.
I'll have to give it a try with my 4x LER setup so I can actually see what I'm aiming at.
I'm up to about 160 rounds through it and no malfunctions of any sort. The ejection is quite different than my 858s, though. They mostly flip forward about 2 feet in a fairly low arc, as opposed to the near vertical ballistic path of the 858.
