What You Need to Know About Rifle Optics
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adapted to take into account varied natural considerations like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you line up 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 on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other elements. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has identifies where the reticle or crosshair is located relative to the optic’s zoom. It actually implies the reticle is located behind or in front of the magnifying lens of the scope. Looking for the most effective form of rifle optic is dependent on what variety of hunting or shooting you anticipate undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are low
- Experienced shooters who understand their aim point “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) feature the reticle behind the magnification 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 forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who select a clearer optic sight picture without room used up by the larger size FFP reticle
Zoom for Rifle Scopes
The measure of scope magnification you need depends upon the sort of shooting you intend to do. Nearly every type of rifle glass provides some degree of zoom. The amount of zoom a scope provides is identified by the diameter, density, and curvatures of the lenses inside of the rifle optic. The zoom of the optic is the “power” of the glass. This suggests what the shooter is looking at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Optic Info
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust considering that it is a set power scope.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes can be modified between magnified levels. The power adjustment is handled by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Glass
Here are some suggested scope power settings and the distances where they may be effectively used. High power optics will not be as beneficial as lower magnification level glass since too much zoom can be a negative aspect depending on your shooting distance. The same concept goes for extended ranges where the shooter needs to have sufficient power to see where to properly aim the rifle.
Lens Finishing for Rifle Scopes
All modern rifle scope lenses are coated. Lens covering is an important aspect of a rifle when purchasing high end rifle optics and scope equipment.
HD Versus ED Scope Lens Coatings
Some scope suppliers even use “HD” or high-def glass finishings which make the most of various processes, polarizations, chemicals, and elements to extract numerous color ranges and viewable target visibility through the lens. This HD covering is typically used with increased density lens glass which lowers light’s capability to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable over items with hard edges and shapes as light hits the object from particular angles.
Single Covering Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses typically have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing 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 on the scope designer and how much you spent on it. Both the make and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has had several treatments applied to them. If a lens gets several treatments, it can indicate that a producer is taking numerous steps to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not necessarily imply the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the producer’s lens treatment solutions and the quality of glass used in creating the rifle glass.
Details on Hydrophobic Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic anti-water covering.
Glass Mounting Alternatives
Mounting solutions for scopes can be found in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually can be found in quick release variations which use toss levers which permit rifle shooters to rapidly install and dismount the glass.
Rifle Scope Mounting Solutions with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This type of scope mount is effective for rifle systems which need a long lasting, unfailing mount which will not move regardless of how much the scope is moved or jarring the rifle takes. These are the style of mounts you really want to have for a specialized optics setup on a long distance hunting or sniper competition firearm which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another component of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less influenced by temperature level changes and pressure differences from the outdoor environment which might potentially permit 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 look for.
