Sights/Scopes For Your Firearm
A sight is an aiming device used to assist in visually aligning ranged weapons, surveying instruments or optical illumination equipments with the intended target. Sights can be a simple set or system of markers that have to be aligned together with the target (such as iron sights on firearms), or optical devices that allow the user to see a sometimes optically enhanced (e.g. magnified) image of the target aligned in the same focus with an aiming point (e.g. telescopic sights, reflector sights and holographic sights).
