How do firearm scopes work?
The rules for firearm scopes and how they confer their bonus after an Aim maneuver are on B412, “With a fixed-power scope, you must aim for at least as many seconds as the scope’s bonus. With a variable-power scope, you may Aim for fewer seconds, but this reduces your bonus by a like amount.” So, for example, using a rifle with a fixed-power scope and an Accuracy of “6+3” (that is, the weapon has an Accuracy of 6, the scope gives a bonus of +3), the bonuses would accrue as follows: Turn 1: Aim – get +6 for weapon Accuracy (total +6, no bonus from scope yet) Turn 2: Aim – further +1 for Aiming (total +7) Turn 3: Aim – further +1 for Aiming, +3 for scope (total +11) Turn 4: Aim – no further bonuses, total bonus is +11 A variable-power scope set to “+3” would function identically to a fixed-power scope of +3; a variable-power scope set to “+5” (giving the weapon an Accuracy of “6+5”) would function identically to a fixed-power scope of +5, namely: Turn 1: Aim – get +6 for weapon Accuracy
