There's a wee bit of info out there.
He was using a Modified McMillan TAC-50, no particulars on the Mods. Most likely optics and ammo.

Firing from an elevated position Duh... Nothing yet on terrain, engagement or target profiles. It has been verified by stationary camera and "other Data" not live observer, yet. We will have to see how this shakes out. The fact that he put one base let alone in the park at that range is very impressive. I sure hope they get a TOV on this, because that really is an "insanely bitchen shot!"
