What You Need to Know About Rifle Optics
Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of varied environmental considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes have about eleven parts which are located inside and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair lies in connection with the optic’s zoom. It simply means the reticle is located behind or ahead of the magnifying lens of the optic. Picking the most beneficial form of rifle scope depends on what style of hunting or shooting you anticipate doing.
First Focal Plane Scopes
First focal plane optics (FFP) come with the reticle ahead of the magnifying lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at 100 yards using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” plus “lead” relationships for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who select a clearer optic sight picture without space taken up by the bigger FFP reticle
Magnification for Rifle Optics
The amount of magnification a scope supplies is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Scope Info
A single power rifle optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate since it is a fixed power optic.
Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification amount in a format like 2-10×32. These numbers imply the zoom of the scope could be changed in between 2x and 10x power. This also involves the powers in-between 2 and 10. The power manipulation is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
Rifle Optic Power and Range Correlation
Here are some suggested scope powers and the ranges where they can be efficiently used. High power scopes will not be as useful as lower magnification scopes due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same concept relates to extended distances where the shooter needs sufficient power to see where to best aim the rifle.
Optic Lens Finish
All modern rifle scope lenses are layered. There are various types and qualities of finishings. When thinking about luxury rifle optical setups, Lens finish can be an essential component of defining the rifle’s capability. The glass lenses are one of the most essential pieces of the optic given that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area and also improves anti glare from refracted direct sunlight and color presence.
Info on Glass Lens Coatings – HD Versus ED
Some scope companies will also use “HD” or high-definition lense coverings which apply different procedures, rare earth compounds, elements, and polarizations to enhance different color ranges and viewable definition through lenses. This high-definition finishing is often used with more costly, high density lens glass which drops light’s potential to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often visible around items with hard shapes as light hits the item from particular angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Different scope lenses can also have different coatings applied to them. All lenses normally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a covering applied to it so that it will be optimally usable in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope company and how much you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Coatings
Water on a lens does not support keeping a clear sight picture through a scope whatsoever. Many top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Glass on Firearms
Mounting options for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use toss levers which enable rifle operators to rapidly mount and dismount the glass.
Hex Key Optic Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is perfect for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. If they all use a similar design mount, multiple scopes can often be switched out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts come in practical for rifles which are transferred a lot, to remove the glass from the rifle for protection, or for optics which are employed in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Info on Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can spoil a day of shooting and your costly optic by triggering fogging and making residue within the scope tube. A lot of scopes protect against humidity from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the optic still functioning if it goes over the side and you can still find the firearm.
Rifle Glass Gas Purging
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the optic is less impacted by temp alterations and pressure differences from the outside environment which might potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
