What You Need to Know About Scopes
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by utilizing a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied natural considerations like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have around 11 parts which are found inside and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has determines where the reticle or crosshair lies relative to the scopes magnification. It actually suggests the reticle is behind or ahead of the magnifying lens of the scope. Selecting the most beneficial style of rifle scope is dependent on what type of hunting or shooting you anticipate undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle to the rear of 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 reticle measurement.
- Far away types of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots take place within much shorter ranges and distances
- Shooters who would like a clearer optic sight picture with less space taken up by the bigger FFP reticle
Ins and Outs of Rifle Glass Zoom
The amount of zoom a scope supplies is determined 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.
Single Power Lens Scopes
A single power rifle scope uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate considering that it is a fixed power optic.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some recommended scope power settings and the distances where they could be successfully used. Bear in mind that higher power optics and scopes will not be as effective as lower powered optics and scopes since excessive magnification can be a bad thing. The exact same idea applies to longer distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
Glass Lens Finishing
All top of the line rifle scope and optic lenses are layered. Lens coating can be a vital aspect of a rifle system when purchasing high end rifle optics and scope equipment.
HD Versus ED Lenses
Some optic companies even use “HD” or high-definition lens finishes which use various procedures, polarizations, chemicals, and components to enhance a wide range of colors and viewable definition through the lens. This high-def covering is frequently used with increased density lens glass which decreases light’s potential to refract through the lens glass. Some scope corporations use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain 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 visible over objects with defined outlines as light hits the item from particular angles.
About Single Covering Versus Multi-Coating
Different optic lenses can also have different finishes used to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 upon the scope manufacturer and how much money you spent paying for it. Both are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Details on Hydrophobic Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Alternatives for Mounting Scopes on Firearms
Mounting approaches for scopes can be found in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally are made in quick release versions which use throw levers which allow rifle shooters to rapidly mount and remove the scopes.
Hex Key Scope Rings
Standard, clamp-on design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This kind of scope mount is great for rifles which need to have a resilient, unfailing mount which will not shift regardless of just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should get for a dedicated scope setup on a long distance hunting or tournament firearm that will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screws from backing out after they are installed safely in place. An example of these rings are the 30mm style made by 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 rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible design mount. These types of mounts are convenient for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used between numerous rifles.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less altered by temperature level alterations and pressure variations from the outside environment which might potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
