I have 3 Sim 4s and 1 ACP 2.0 of them. Along with tons of rail accessories and scopes ariakon accessories not shown, an etrigger somewhere, 2 qloader sets adjusted for the sim 4s.
All of them have wobbles eliminated along with some mods I did to get rid of potential leaks. Along with spare parts, I have the first prototypes of the delrin striker mod I was help testing out before release along with delrin o-rings and other weird goodies.
From what I remember, Sim 4s
-delrin low blow bolt
HP high flow spyder valve
Flat top rail
Some grip of a warsensor or something
I don't remember the other mods but this one might have been more modded than the other marker
