really any low powered quality scope would do just fine. You get what you pay for in optics so I would go for a Nikon or Leupold instead of a tasco or BSA. I have a 1.5 - 4x nikon with the turkey plex and i think its about perfect. I have taken four birds with it so far. I used to laugh at the thought of using a scope to shoot a turkey at 30 yards, now i don't know how i did it without one haha.
