Rifle Scope Details
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 magnification by employing a series of lenses inside the scope. The scope’s alignment can be adapted to account for different natural factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have about eleven parts which are arranged within and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the optimal type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the zoom lens. This induces the reticle to remain at the exact same overall size in connection with the quantity of magnification being used. The outcome is that the reticle measurements adapt based upon the zoom applied to shoot over greater ranges due to the fact that the reticle measurements present distinct increments which can vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These types of scopes work for:
- Long distance types of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who desire a clearer optic picture with less room used up by the larger size FFP reticle
Magnification for Rifle Optics
The quantity of scope zoom you need on your scope depends upon the kind of shooting you want to do. Nearly every kind of rifle scope supplies some amount of magnification. The volume of magnification a scope provides is identified by the dimension, density, and curvatures of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is magnified times the power element of what can typically be seen by human eyes.
Fixed Power Lens Rifle Optics
A single power rifle 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 magnification of this type of optic can not change because it is set from the factory.
Variable Power Lens Scope Info
Variable power rifle scopes can be changed between magnification levels. These types of scopes will note the magnification degree in a configuration like 2-10×32. These numbers indicate the magnification of the scope could be changed in between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Scope Power Level and Range Correlation
Here are some suggested scope power levels and the ranges where they may be efficiently used. Highly magnified optics will not be as efficient as lower powered scopes considering that too much zoom can be a negative aspect depending on your shooting distance. The same idea goes for longer ranges where the shooter needs adequate power to see where to best aim the rifle.
Optic Lens Coating
All modern rifle glass lenses are covered. Lens covering is an essential aspect of a rifle’s setup when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle glass manufacturers additionally use “HD” or high-def lense finishes which make the most of various procedures, polarizations, chemicals, and elements to draw out numerous colors and viewable definition through lenses. This high-def coating is often used with more costly, high density glass which lowers light’s potential to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around objects with defined outlines as light hits the object from particular angles.
Single Optic Lens Coating Versus Multi-Coating
Various scope lenses can also have various finishes applied to them. All lenses normally have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It must have a finish placed on it so that it will be optimally functional in many kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope developer and how much money you paid for it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can prove that a maker is taking multiple actions to combat different natural factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also doesn’t necessarily indicate the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the maker’s lens treatment innovation and the quality of materials used in building the rifle optic.
Details on Anti-water Finish
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic finish.
Alternatives for Installing Glass on Long Guns
Installing approaches for scopes are available in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which enable rifle shooters to rapidly install and remove the glass.
Hex Key Scope Ring Mounts
Normal, clamp design 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is excellent for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts are handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles or are situationally focused.
Info Around Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can spoil a day on the range and your costly optic by inducing fogging and making residue within the scope tube. Many scopes prevent moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for conventional use rifles, unless you intend on taking your rifle sailing and are worried about the scope still performing if it goes overboard and you can still salvage the firearm.
What to Know About Scope Tube Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the scope is less impacted by climate changes and pressure variations from the external environment which might possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
