Battlefield 4 XP boosts

It is the zeroing mechanism. This means that if you have it zeroed at 500m, the cross-hairs are dead on at 500m. This allows you to make distance shots much easier. If you were to zero the scope at 500m and shoot at a target at 100m, your shot would hit much higher than your cross-hairs. Previously, your only option was to compensate for bullet drop by aiming high and guessing between mil dots, which made distance shots on moving targets much more difficult. If you have your scope properly zeroed, now you can just offset the horizontal reticule the appropriate lead for motion.

Based on your prices and info from origin would seem like you're talking about normal battlefield 4 and battlefield 4 digital deluxe version.

Origin states that: "Digital Deluxe Edition also includes 3 Gold Battlepacks and a BF3 Vehicle Shortcut Bundle"

BUT on an another page in origin it states that you get the first expansion called china rising in the digital deluxe version and 3 gold battle packs.

battle packs are ingame unlockable items and vehicle shortcut bundle seems to unlock all the vehicle unlockables for you.
