Welcome back guy! We have missed your knowledge! You have forgotten more about building than most of us know. Hope your biz is still rocking. That looks like one seriously nasty piece of equipment in the pictures. What kind of glass ya got on top?
That is a Vortex Razor Gen III, 6-36. Euro Optics had a run done in black. In a ARC mount (I have four of these mounts)
The rifle came from Phil At MPA with his Matrix Pro chassis (midnight bronze cerakote), “Spencer” barrel, ARC/MPA “Coup de Grace” action, Trigger Tech single Diamond.
