What You Need to Know About Rifle Optics
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target at range. They do this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of different natural things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have about 11 parts which are arranged within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the perfect type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Glass
First focal plane glass (FFP) come with the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minor
- Experienced shooters who understand their aim point “hold over” plus “lead” equations for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the zoom lens. This triggers the reticle to remain at the exact same dimensions in connection with the amount of magnification being used. The outcome is that the reticle measurements change based on the zoom chosen to shoot over greater ranges since the reticle markings present various increments which vary with the zoom. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These particular types of optics work for:
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within much shorter distances and ranges
- Shooters who would like a clearer optic picture without area taken up by the bigger FFP reticle
Magnification for Optics
The extent of scope magnification you need on your optic depends on the style of shooting you choose to do. Pretty much every style of rifle glass delivers some degree of zoom. The level of magnification a scope supplies is identified by the dimension, density, and curvatures of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the glass. This denotes what the shooter is looking at through the scope is amplified times the power factor of what can usually be seen by human eyes.
Info About Single Power Lens Glass
A single power rifle optic and scope comes with 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 zoom of this type of optic can not fluctuate given that it is a fixed power scope.
Variable Power Lens Optic Details
Variable power rifle scopes use enhanced power. The power change is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some advised scope power settings and the ranges where they can be successfully used. Keep in mind that higher power scopes and optics will not be as effective as lower magnification level scope and optics since too much magnification can be a detractor. The same idea applies to extended ranges where the shooter needs increased power to see where to properly aim the rifle at the target.
Info on Optic Lens Coatings
All top teir rifle optic and scope lenses are coated. Lens coating can be an essential aspect of a shooting system when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle scope companies will also use “HD” or high-definition lense coatings which employ various processes, elements, compounds, and polarizations to extract separate color ranges and viewable target definition through lenses. This HD finish is often used with increased density glass which drops light’s capability to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be visible over things with well defined shapes as light hits the object from specific angles.
Single Covering Versus Multi-Coating for Rifle Glass
Different scope lenses can also have different finishings applied to them. All lenses generally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a finish placed on it so that the lens will be optimally functional in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Scope Lens Finish
Water on a lens doesn’t assist with preserving 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 coating.
Rifle Optic Installation Choices
Installing solutions for scopes are available in a few choices. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also normally come in quick release versions which use manual levers which allow rifle operators to rapidly mount and remove the glass.
Hex Key Scope Rings
Normal, clamp style 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is fine 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 Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles.
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle optic can spoil a day on the range and your costly optic by resulting in fogging and making residue inside of the scope’s tube. Many optics prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof. Normally, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content avoidance for standard use rifles, unless you anticipate taking your rifle boating and are concerned about the scope still working if it is submerged in water and you can still salvage the firearm.
Rifle Scope Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less affected by temperature level shifts and pressure differences from the external environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
