What You Need to Know About Rifle Optics
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account different environmental factors like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have around eleven parts which are located internally and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other parts. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the perfect type of rifle scope depends on what type of shooting you plan to do.
About First Focal Plane Glass
First focal plane scopes (FFP) include the reticle ahead of the zoom lens. This causes the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who know their target “hold over” and also “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who choose a clearer optic sight picture with less room used up by the larger size FFP reticle
Rifle Optic Magnification
The amount of magnification a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Power Lens Optics
A single power rifle scope and optic will have a zoom 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 type of scope can not change since it is fixed.
Info on Variable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Scopes
Here are some suggested scope power levels and the distances where they could be effectively used. Highly magnified optics will not be as useful as lower powered rifle scope glass considering that too much zoom can be a negative aspect depending on your shooting distance. The same concept applies to extended ranges where the shooter needs to have increased power to see exactly where to best aim the rifle.
Optic Lens Finish
All contemporary rifle scope lenses are layered. There are different types and qualities of glass lens finishings. Lens covering can be an essential element of a rifle when thinking about high end rifle optics and scope systems. The glass lenses are among the most essential parts of the scope given that they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area and also helps with anti glare capabilities from excess daylight and color recognition.
HD Versus ED Rifle Scope Lens Coatings
Some rifle glass companies additionally use “HD” or high-definition glass coverings which use different procedures, rare earth compounds, polarizations, and aspects to draw out various colors and viewable target definition through lenses. This high-definition finishing is frequently used with higher density glass which reduces light’s ability to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable over objects with well defined outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating for Rifle Scopes
Different optic lenses can likewise have various finishings applied to them. All lenses generally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets multiple treatments, it can establish that a maker is taking several actions to combat various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally doesn’t necessarily suggest the multi-coated lens is better than a single covered lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of products used in developing the rifle optic.
Anti-water Lens Coatings
Water on an optical lens does not help with retaining a clear sight picture through a scope in any way. Many top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Options for Installing Rifle Scopes on Long Guns
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually can be found in quick release variations which use throw levers which permit rifle operators to rapidly mount and dismount the scope.
Hex Key Rifle Scope Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is wonderful for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be switched on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These kinds of mounts are useful and handy for rifles which are shipped a lot, to take off the scope from the rifle for protection, or for optics which are utilized in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and generating residue within the scope’s tube. Most optics prevent moisture from getting in the scope tube with a series of sealing O-rings which are waterproof. Typically, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample humidity prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the optic still working if it goes over the side and you can still salvage the gun.
Info on Rifle Glass Tube Gas Purging
Another element of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by temp alterations and pressure differences from the outside environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
