Scope, among gun enthusiasts, hunters and snipers, refers to an optical device that assists in shooting accuracy. The purpose of sights is to hit your target. If your vision has deteriorated enough that you cannot effectively use iron sights at long range, or if you expect lots of low-light combat, then a quality optical sight is necessary for your battle rifle.
To quote Boston's Gun Bible, "As soon as you add a scope to a hunting rifle, liberals call it a "sniper rifle". This is politically correct PolSpeak for any rifle with a scope. The anti-gun pols are finally realizing the awesome capability of scoped, high-powered rifles, which make the AK-47 look puny by comparison. As I predicted in 1998, this pejorative term is becoming a gunphobe buzzphrase (like "cult," "compound," "patriot," "militia," "Saturday night specials," "assault weapons" and "cop killer bullets")."
Different optics for different rifles
Battle Rifle Optics
Battle rifle optics include for example Burris 3-9x Fullfield II. According to Boston T Party, "Optics must be very rugged and versatile. Rugged because a .308 MBR has hefty recoil and sees hard use. Versatile because the battle rifle will be employed for everything from CQB to precision work. Hence, it must have a quickly acquired point of aim, as well as range finding stadia lines and a BDC. The scope mount should be see-through in order to have immediate use of the iron sights. While I have a lot of experience with the I.O.R. M2 4x units, the Burris Fullfield II ballistic-Plex scopes have now gained my favor as very affordable and rugged optics for battle rifles."
Battle Carbine Optics
Battle carbine optics include for example the ACOG. According to Boston, "Optics must be rugged, lightweight, and offer very fast target acquisition for CQB. A circle, dot, or triangle point of aim is the norm, and it should be illuminated at all times day or night (e.g., ACOG "BAC" system with tritium). Distance stadia lines are nice (e.g., ACOG), but not absolutely necessary (e.g., the AUG's 5MOA 'doughnut of death"). As in battle rifles, the scope mount should also be see-through if possible."
Tactical Rifle Optics
Tactical rifle optics include for example the Shepherd 310-P2. According to Boston, "If you needed to make a 250 yard head shot or 600yd body shot, this is the rifle you'd want. (Also called a "precision rifle" or "countersniper" rifle.) Hence, it will have something like a 3-9x magnification scope with at least 1/2MOA adjustments (if not 1/4MOA). The reticle will likely be Mil Dot, and the scope will have a BDC. Some battle rifle optics make for very competent tactical applications, such as the Burris Ballistic-Plex units. Because of the higher accuracy requirement, these rifles are often, if not usually, bolt actions. But, not always. An M14 can make a fine tactical rifle if tuned to <1 1/4M0A accuracy."
