First 3 all have a different reticle. Have a look on the vortex page to see what they look like. Target shooters will pick the reticle that matches the ammunition they use. So the marks accurately represent the correct bullet drop at range.

Air rifle shooters like 1/2 mildot reticles, As it gives a scale you can use with a range-finder. You will know from a table or program that a 45yrd shot needs 2.5mill dot holdover to hit on target ect. In the correct situation it's very useful, but not so much for airsoft.

The last one is a different reticle and it has longer eye relief. So the internals will be different.

Ahaha thanks, guess imma go for the more expensive scout version... or maybe this: https://www.uttings.co.uk/p123875-vortex-crossfire-ii-1-4x24-rifle-scope-cf2-31037/#.XCq26lyTKUl
