i have one and shot it first time yesterday. trigger is awful and accuracy is awesome for a 16 inch barrel. i was shooting groups about a eight of an inch apart at 50 yards with match ammo (not the **** zq ammo i had) i was going to switch out the trigger and then go to a hundred but my drop in trigger would not go in without removing the ambi bolt catch. all the controls are stiff except safety and u should expect a long break in...also i was going to suppress this but silencerco adapter would not thread on. my gunsmith is going to have to figure out this problem. the gun is good for the money but needs refinement in my opinion
