My thoughts exactly. More guns need better UX design. The Garand had its ping, this gun has its dud-dud, the barret 50 cal blows a lil hiss of gas out the bottom of the mag when its empty like an exasperated sigh, the P90 you can literally just see the last round get sucked into its witchcraft mechanism.
A proper tactile, audible and visual feedback with practical application is called a bolt hold open and it even speeds up a reload.
Wondering if you felt x-1 rounds leave the rifle to determine if a reload is needed is the kind of engineering that made even the french abandon this for a german made HK416
