muzzy, sorry to say the NAP won't make center shot. I tried a 4000 on my OG. A Trophy Taker with the extended windage bar will. An HHA TR 1000 is on mine right now. Plenty of movement. It's like a cross between the NAP 2000 and a TT. I can post a pic if needed. BTW, I'm attached to the slide for lifting the rest.
