Optic Information
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to account for varied environmental considerations like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have around 11 parts which are located internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage dials, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle glass is based around what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who want a clearer optic picture with less space used up by the larger sized FFP reticle
About Rifle Scope Magnification
The extent of scope magnification you need on your scope is based on the type of shooting you choose to do. Just about every kind of rifle scope provides some amount of magnification. The amount of zoom a scope supplies is established by the size, density, and curves of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This signifies what the shooter is aiming at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Info on Fixed Single Power Lens Rifle Scopes
A single power rifle scope and optic uses a magnification 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 optic can not fluctuate since it is fixed.
Info on Variable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Range Correlation
Here are some advised scope powers and the distances where they may be efficiently used. Keep in mind that higher power optics and scopes will not be as practical as lower magnification level optics and scopes since excessive zoom can be a negative thing in certain situations. The very same idea relates to longer distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle at the target.
Lens Finish for Rifle Glass
All modern rifle scope lenses are layered. There are various types and qualities of lens coverings. Lens finishing is an important aspect of a rifle when considering high-end rifle optics and targeting equipment. The glass lenses are among the most significant parts of the scope given that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens surface as well as helps with anti glare capabilities from excess light and color perception.
HD Versus ED Rifle Glass Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coatings which use various procedures, chemicals, elements, and polarizations to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard 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 covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Glass Lens Finishing
Water on a lens does not help with keeping a clear sight picture through an optic in any way. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Scope Mounting Alternatives
Mounting approaches for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally are made in quick release variations which use throw levers which enable rifle shooters to rapidly install and remove the scopes.
Hex Key Scope Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is excellent for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining the original sighting settings. These kinds of mounts are useful and practical for shooting platforms which are transported a lot, to take off the scope glass from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
What to Know About Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Info Around Scope Tube Gas Purging
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the glass is less altered by climate alterations and pressure variations from the outside environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
