Sounds like it might be "hold" sensitive sort of like "limp writings" some pistols.
I was pretty fired up when they were first announced years ago... looked like a nice rifle at a great price boasting of AK reliability and Swiss precision.
The new m10x gen 3 + (plus) has all new upgraded internals/springs and the upper receiver has been weight reduced with more ports/venting
Reminds me of my CZ 858, quietly rusting in the safe!
