What You Need to Know About Rifle Scopes
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by making use of a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of different environmental considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around 11 parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane an optic has identifies where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It actually indicates the reticle is located behind or before the magnifying lens of the optic. Picking the most effective form of rifle glass is based on what type of shooting or hunting you anticipate undertaking.
Info About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who desire a clearer optic picture with less space taken up by the larger size FFP reticle
Zoom for Glass
The extent of scope zoom you need on your scope depends on the kind of shooting you would like to do. Almost every style of rifle optic supplies some level of zoom. The amount of magnification a scope offers is established by the dimension, thickness, and curves of the lenses within the rifle optic. The zoom of the optic is the “power” of the opic. This means what the shooter is aiming at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle optic and scope uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate considering that it is fixed.
Adjustable Power Lens Optic Facts
Variable power rifle scopes use enhanced power. The power change is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope powers and the ranges where they could be successfully used. High power glass will not be as useful as lower magnification scopes given that too much magnification can be a bad thing. The same applies to longer ranges where the shooter needs sufficient power to see precisely where to best aim the rifle.
About Lens Coatings
All top teir rifle scope lenses are layered. Lens finish can be a crucial aspect of a rifle system when thinking about high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some optic manufacturers even use “HD” or high-definition glass finishes which take advantage of various processes, polarizations, elements, and chemicals to extract numerous color ranges and viewable target visibility through the lens. This HD finishing is normally used with more costly high density glass which brings down light’s chance to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard outlines as light hits the object from specific angles.
Rifle Optic Lens Single Covering Versus Multi-Coating
Different scope lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in numerous kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope developer and the amount you spent for it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a manufacturer is taking several actions to combat various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not necessarily mean the multi-coated lens will perform better than a single coated lens. Being “much better” depends on the maker’s lens treatment solutions and the quality of components used in building the rifle scope.
Anti-water Rifle Scope Lens Coating
Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Rifle Optic Installing Alternatives
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use toss levers which allow rifle shooters to rapidly mount and remove the glass.
Scope Mounts with Hex Key Rings
Basic, clamp design mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This kind of scope mount is very good for rifles which need to have a long lasting, hard use mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a dedicated scope setup on a reach out and touch someone hunting or hard target interdiction rifle which will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to prevent the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm style from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a comparable design mount, a number of scopes can also be switched on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining precision. These kinds of mounts are useful and beneficial for shooting platforms which are transferred a lot, to take off the optic from the rifle for protection, or for aiming systems which are employed in between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle scope can wreck a day on the range and your pricey optic by triggering fogging and making residue within the scope tube. The majority of optics prevent wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Generally, these water resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture avoidance for common use rifles, unless you intend on taking your rifle sailing and are concerned about the scope still functioning if it falls overboard and you can still recover the firearm.
Gas Purged Optic Tubes
Another element of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less impacted by condition alterations and pressure differences from the external environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
