Looks like a 2k7ish Spyder. I don't know the exact model, but there isn't much difference between them. You also have an earlier version of the Spyder Rocking Trigger. The front block is upgraded from an older 2k3ish spyder xtra (allows it to actually have an aftermarket regulator).
Says acs on the side. After looking into it
