I current have just the xfive trigger installed onto a stock fcu(made after the vup), it's too squishy for my liking. there is also a noticeable "click" at the beginning of the wall before the break. When looking into the back of the gun it's right at the bottom of the sear, so I'm assuming just a bad factory machine job. This is why I dont think the apex bar and trigger will help, I would need a new sear much like how the gray guns kit comes with/installed with, Bruce at gray guns informed me he cannot send that set up to me due to ITAR.
Those of you with the apex installed does your striker sit at the very bottom of the sear?
