What You Need to Know About Rifle Scopes
Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for different ecological aspects like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle optics have about eleven parts which are located inside and outside of the optic. These parts include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located relative to the optic’s magnification. It literally indicates the reticle is behind or in front of the magnifying lens of the optic. Deciding on the very best kind of rifle glass is based upon what form of shooting you anticipate doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who understand their target “hold over” and “lead” ratios for their firearms
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Glass
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 reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who select a clearer optic sight picture with less room used up by the enlarged FFP reticle
Glass Magnification
The extent of scope magnification you need on your scope depends on the kind of shooting you want to do. Virtually every type of rifle glass delivers some amount of zoom. The quantity of zoom a scope provides is determined by the diameter, thickness, and curves of the lens glass within the rifle scope. The magnification of the optic is the “power” of the scope. This signifies what the shooter is looking at through the scope is amplified times the power element of what can typically be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change because it is set from the factory.
Info on Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification degree in a format like 2-10×32. These numbers imply the magnification of the scope can be changed in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some recommended scope power levels and the ranges where they may be effectively used. Keep in mind that high magnification optics and scopes will not be as efficient as lower magnification level glass because increased zoom can be a negative thing in certain situations. The exact same idea relates to longer distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
About Glass Lens Coverings
All contemporary rifle optic lenses are coated. There are various types and qualities of lens finishings. Lens coating is an important element of a rifle when thinking about high end rifle optics and targeting equipment. The glass lenses are among the most essential pieces of the scope since they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface area and also assists with anti glare from refracted direct sunlight and color profiles.
HD Versus ED Lens Coatings
Some rifle glass producers will also use “HD” or high-definition lense finishings which take advantage of various procedures, polarizations, rare earth compounds, and components to draw out different color ranges and viewable target definition through lenses. This high-def finishing is typically used with higher density lens glass which brings down light’s potential to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable around objects with well defined outlines as light hits the object from particular angles.
What to Know About Single Finish Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in lots of kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
About Hydrophobic Finishing
Water on a lens does not assist with keeping 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 hydrophilic or hydrophobic covering.
Options for Installing Rifle Scopes on Long Guns
Mounting approaches for scopes are available in a couple of options. 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 normally come in quick release versions which use toss levers which enable rifle operators to rapidly install and remove the scopes.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, clamp-on design mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use a pair of detached rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This type of scope mount is exceptional for rifles which need to have a long lasting, hard use mount which will not change regardless of just how much the scope is moved or jarring the rifle takes. These are the style of mounts you really want to have for a dedicated optics setup on a long distance scouting or competitors rifle which will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screws from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts are handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another component of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less impacted by condition alterations and pressure differences from the external environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
