What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adjusted to account for varied ecological aspects like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about eleven parts which are found internally and externally on the optic. These parts include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has establishes where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It actually implies the reticle is situated behind or before the magnifying lens of the optic. Picking the most ideal style of rifle scope is based on what form of shooting or hunting you plan on undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their long gun
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who select a clearer optic sight picture without room used up by the enlarged FFP reticle
Rifle Glass Zoom
The amount of zoom a scope offers is identified 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.
About Fixed Power Lens Rifle Scopes
A single power rifle scope and optic comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust considering that it is fixed.
Info on Variable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the magnification amount in a format such as 2-10×32. These numbers imply the zoom of the scope could be adjusted between 2x and 10x power. This also includes the powers in-between 2 and 10. The power adjustment is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some recommended scope powers and the ranges where they could be efficiently used. High power scopes will not be as beneficial as lower magnification level rifle scope glass due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same concept goes for longer distances where the shooter needs enough power to see where to properly aim the rifle at the target.
Lens Covering for Optics
All present day rifle optic lenses are layered. Lens finishing is a significant element of a rifle system when purchasing high end rifle optics and scope setups.
HD Versus ED Optic Lens Coatings
Some scope producers also use “HD” or high-def glass finishings that apply various procedures, polarizations, aspects, and chemicals to extract numerous colors and viewable target visibility through lenses. This HD finish is often used with greater density lens glass which reduces light’s chance to refract through the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious around things with defined outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating for Glass
Various optic lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or coating applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in numerous types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing 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 on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can indicate that a company is taking multiple actions to fight various environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also doesn’t necessarily indicate the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the maker’s lens treatment technology and the quality of glass used in creating the rifle optic.
Hydrophobic Finish for Glass
Water on a scope lens doesn’t support preserving a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finish. 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 molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Glass Installation Options
Installing options for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 developed for long distance precision shooting. This type of scope install is great for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Multiple scopes can also be swapped out if they all use a similar design mount. These types of mounts come in handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
Info on Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your highly-priced optic by causing fogging and generating residue within the scope’s tube. Many optics protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content avoidance for conventional use rifles, unless you anticipate taking your rifle sailing and are concerned about the optic still working if it goes over the side and you can still retrieve the firearm.
Gas Purged Rifle Glass Tubes
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less influenced by temp shifts and pressure differences from the outside environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
