Scope (Fallout Supplement)
From D&D Wiki
A scope is a sighting device that makes it easier to hit targets at long range. However, although a scope magnifies the image of the target, it has a very limited field of view, making it difficult to use.
Standard: A standard scope increases the range increment for a ranged weapon by one-half (multiply by 1.5) and give the character a +1 situational bonus to attack rolls while using the scope. However, to use a scope a character must spend an attack action acquiring his or her target. If the character changes targets or otherwise lose sight of the target, he or she must reacquire the target to gain the benefit of the scope.
Cost: 4 TU/40 Caps
Electro-Optical: An electro-optical scope functions the same as a standard scope in normal light. In darkness, however, the user sees through it as if he or she had the darkvision ability granted by night vision goggles.
Cost: 6 TU/60 Caps
