Rifle Scopes – Nowadays, most firearm enthusiasts use some sort of rifle scope to simplify their target acquisitions whether for hunting or target shooting with rifles. Rifle scopes can be fitted on either rifles, or shotguns. In lieu of lining up the rear sight with the front sight and the target, gun scopes utilize magnification and crosshairs (reticle) to ensure a more precise shot on the target. A reticle is the pattern placed in the eyepiece of rifle scopes which helps to establish the firearm’s position on the target and you need to make sure that you choose a reticle for that fits to your specific type of shooting. For example, long range shooting, hunting or competitive shooting, you should consider rifle scopes that utilize a reticle without a dot that could potentially obscure your target. Most rifle scopes also have adjustable eyepieces so that people with less than perfect vision can focus the eyepiece for a clear, crisp sight picture.
The objective (or front) lens size is its diameter measured in millimeters (mm) and generally range in size from 32 to 75mm. It is important to understand that the scope’s function is not for gathering or amplifying light; they only transmit the available light to your eyes. The larger the rifle scopes objective lens, the brighter, and higher contrast and clarity of the target image. However, the negative side to a larger objective lens is that the bigger glass elements make rifle scopes a heavier weight. Even a high performance scope will not be accurate if it is not mounted on a stable platform. To improve the viewing through rifle scopes, an anti reflective coating is deposited on lens surfaces to reduce light reflection off the glass lens and allow more light to pass through the rifle scopes to your eyes.
The rifle scopes magnification is identified by a range of numbers that are separated by a hyphen. The most common magnification is a 9X. Beware of the notion that “the more magnification – the better.” In reality, the more magnification you have with rifle scopes, the less light that gets to your eyepiece while reducing the rifle scopes field of view. Anything greater than 12X will be susceptible to the natural shake that comes with holding a firearm which tends to blur the magnified image. Be aware of a common mistake, many shooters purchased expensive rifle scopes but then they cuts corners and mount them using cheap or mismatched bases and rings.
Before you can properly determine what type of rifle scopes that you will need, you should become familiar with the definitions described in the Gun Scopes Terms post. Exit pupil, eye relief, field of view, lens coating, objective lens, parallax adjustments, reticles, turret adjustment and minute of angle (MOA), and bullet drop compensation (BDCs), are all terms to understand when selecting the appropriate rifle scopes.
