Facts About Rifle Scopes
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They do this through zoom using a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of numerous ecological things like wind speed and elevation to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern rifle scopes have around eleven parts which are located internally and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has identifies where the reticle or crosshair is located in connection with the scopes magnification. It simply suggests the reticle is situated behind or in front of the magnifying lens of the optic. Considering the most ideal style of rifle glass is dependent on what form of shooting or hunting you plan on undertaking.
First Focal Plane Scope Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who know their target “hold over” and “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who prefer a clearer optic sight picture without room used up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Magnification
The quantity of zoom a scope supplies is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass
A single power rifle scope comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not adjust given that it is a fixed power optic.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification levels. It will list the magnification degree in a format like 2-10×32. These numbers indicate the magnification of the scope could be adjusted between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power modification is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope powers and the ranges where they could be effectively used. Always remember that higher power scopes will not be as efficient as lower powered optics and scopes because excessive zoom can be a bad thing. The same concept applies to extended distances where the shooter needs increased power to see exactly where to best aim the rifle at the target.
Details on Lens Coatings
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of glass lens coatings. Lens finishing can be an important element of a rifle’s setup when looking into high-end rifle optics and targeting units. The lenses are among the most vital pieces of the optic as they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses protects the lens exterior and even improves anti glare capabilities from refracted light and color profiles.
ED Versus HD Rifle Optics
Some glass makers will also use “HD” or high-def lens finishings that take advantage of various processes, chemical applications, polarizations, and aspects to extract various color ranges and viewable definition through lenses. This high-definition covering is commonly used with greater density glass which drops light’s capability to refract through the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration may be visible over things with defined outlines as light hits the object from specific angles.
Single Finish Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses typically have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering 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 signs of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can establish that a producer is taking numerous actions to combat various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also doesn’t necessarily mean the multi-coated lens will perform better than a single coated lens. Being “much better” depends upon the producer’s lens treatment innovation and the quality of glass used in creating the rifle glass.
Hydrophobic Covering for Rifle Optics
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Installing Rifle Glass on Long Guns
Installing options for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use manual levers which enable rifle operators to quickly mount and remove the optics.
Hex Key Rifle Optic Ring Mounts
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 are created for long range accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be swapped in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts come in practical for shooting platforms which are transferred between vehicles a lot, to take off the optic from the rifle for protection, or for optics which are adopted in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can spoil a day of shooting and your highly-priced optic by triggering fogging and making residue inside of the scope’s tube. Many scopes protect against moisture from getting in the scope tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture prevention for common use rifles, unless you intend on taking your rifle aboard watercrafts and are concerned about the optic still functioning if it goes over the side and you can still recover the rifle.
Info on Scope Tube Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less altered by temperature level changes and pressure distinctions from the outside environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
