Luckily I managed to get shot of the Nikko so you will have to go and look at specs for comparison.
3. I bought mine from falcon uk direct but opticswarehouse do them i think
4. Yes it's very very close to a sightron, all but the reticle. But thats just my opinion.
5. £699 without sidewheel.
As I own both and am able to compare and if I needed another FT scope I would buy the Falcon.
Bare in mind I'm an old git and have crap eyes. But both scopes certainly suit them.
Hope that helps.
