What You Need to Know About Rifle Optics
Rifle scopes enable you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification by employing a series of lenses within the scope. The scope’s alignment can be dialed in for the consideration of many ecological considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes have around eleven parts which are located within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the perfect type of rifle optic is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who understand their target “hold over” as well as “lead” equations for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. This induces the reticle to remain at the same overall size in relation to the volume of zoom being used. The effect is that the reticle dimensions shift based on the zoom used to shoot over longer distances since the markings represent various increments which vary with the zoom level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These varieties of scopes are handy for:
- Far away kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who select a clearer optic sight picture with less area used up by the bigger FFP reticle
Details on Rifle Optic Magnification
The quantity of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optics
A single power rifle scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust since it is fixed.
Variable Power Lens Scope Details
Variable power rifle scopes can be modified between magnified settings. The power change is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the distances where they can be successfully used. High power scopes will not be as beneficial as lower magnification optics given that too much magnification can be a negative aspect depending on your shooting distance. The very same idea goes for extended ranges where the shooter needs to have sufficient power to see where to best aim the rifle.
Lens Finishing for Optics
All contemporary rifle scope lenses are coated. There are different types and qualities of glass coatings. When thinking about high end rifle targeting systems, Lens covering can be an important aspect of defining the capability of the rifle. The lenses are among the most crucial pieces of the glass due to the fact that they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses offers protection to the lens surface area and even assists with anti glare capabilities from refracted sunlight and color presence.
HD Versus ED Lens Coatings
Some optic companies additionally use “HD” or high-def lens coverings which apply various processes, polarizations, elements, and chemicals to enhance different colors and viewable definition through lenses. This high-def covering is often used with more costly, high density glass which reduces light’s capability to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be obvious around objects with well defined outlines as light hits the item from various angles.
Single Glass Lens Finishing Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope producer and the amount you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has had several treatments applied to them. If a lens gets multiple treatments, it can indicate that a manufacturer is taking several steps to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally doesn’t necessarily indicate the multi-coated lens will perform better than a single layered lens. Being “much better” depends upon the manufacturer’s lens treatment solutions and the quality of glass used in constructing the rifle optic.
Hydrophobic Lens Coating
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic covering which is water repellent.
Options for Installing Optics on Firearms
Installing solutions for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release versions which use toss levers which enable rifle operators to rapidly mount and remove the glass.
Hex Key Rifle Optic Rings
Standard, 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 two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and beneficial for rifles which are transferred a lot, to remove the glass from the rifle for protection, or for sight systems which are employed in between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less influenced by temperature level changes and pressure distinctions from the outdoor environment which might potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
