Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be adapted to account for different environmental aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have around 11 parts which are located internally and outside of the scope body. These scope parts include the rifle scope’s body, lenses, modification turrets, focus rings, and other elements. Learn about the eleven parts of rifle glass.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who recognize their target “hold over” and also “lead” equations for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who select a clearer optic sight picture without space used up by the enlarged FFP reticle
Rifle Glass Zoom
The level of scope zoom you require depends upon the style of shooting you choose to do. Nearly every kind of rifle scope delivers some level of zoom. The volume of zoom a scope delivers is established by the dimension, density, and curves of the lens glass within the rifle optic. The zoom of the optic is the “power” of the glass. This implies what the shooter is aiming at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Scopes
A single power rifle scope will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not adjust considering that it is a set power scope.
About Variable Power Lens Optics
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the magnification amount in a format such as 2-10×32. These numbers mean the magnification of the scope could be changed between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power adjustment is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some recommended scope powers and the ranges where they can be successfully used. Highly magnified rifle scope glass will not be as efficient as lower powered optics given that too much magnification can be a negative aspect depending on your shooting distance. The same relates to extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
About Rifle Scope Lens Finish
All state-of-the-art rifle scope lenses are covered. Lens finishing is a crucial aspect of a shooting platform when considering high end rifle optics and scope setups.
ED Versus HD Optics
Some rifle glass makers will also use “HD” or high-definition glass coatings that employ various procedures, polarizations, chemicals, and aspects to extract separate colors and viewable target definition through the lens. This HD finish is normally used with higher density glass which reduces light’s chance to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible over things with defined outlines as light hits the object from various angles.
Single Finishing Versus Multi-Coating for Scopes
Various optic lenses can also have different finishings used to them. All lenses usually have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Lens Finishes
Water on a scope’s lens does not assist with maintaining a clear sight picture through a scope in any way. Lots of top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Mounting approaches for scopes come in a few options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release versions which use manual levers which permit rifle shooters to quickly mount and remove the scope.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is perfect for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another part of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less influenced by condition changes and pressure differences from the outdoor environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
