Information Rifle Scopes
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by using a series of lenses within the scope. The scope’s alignment can be adapted to take into account varied ecological things like wind and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. Most modern rifle scopes and optics have about eleven parts which are arranged internally 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 glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the perfect type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” plus “lead” ratios for their long gun
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the very same dimensions in relation to the quantity of zoom being used. The end result is that the reticle dimensions change based on the magnification used to shoot over longer distances since the reticle measurements represent different increments which differ with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of glass are convenient for:
- Far away forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who like a clearer optic picture with less space used up by the bigger FFP reticle
Magnification for Rifle Optics
The quantity of magnification a scope supplies is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass
A single power rifle scope and optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is set from the factory.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will note the zoom level in a configuration like 2-10×32. These numbers indicate the zoom of the scope could be changed in between 2x and 10x power. This additionally incorporates the powers in-between 2 and 10. The power adjustment is accomplished utilizing the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Glass
Here are some advised scope power settings and the ranges where they may be effectively used. Bear in mind that high power optics will not be as practical as lower powered optics because increased zoom can be a negative thing in certain situations. The same goes for longer distances where the shooter needs sufficient power to see where to properly aim the rifle at the target.
Optic Lens Finish
All modern-day rifle scope and optic lenses are layered. There are various types and qualities of glass finishes. Lens coating is a crucial element of a rifle’s setup when considering luxury rifle optics and scope systems. The lenses are among the most crucial components of the scope due to the fact that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens exterior and improves anti glare capabilities from excess sunrays and color discernibility.
HD Versus ED Lens Coatings
Some rifle glass manufacturers will also use “HD” or high-def lens coatings that use various processes, rare earth compounds, elements, and polarizations to enhance different colors and viewable target visibility through the lens. This high-def finish is commonly used with more costly, high density lens glass which lowers light’s opportunity to refract through the lens glass. Some scope producers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be visible over objects with hard edges and shapes as light hits the item from various angles.
Single Coating Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much money you spent for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” coated. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can show that a producer is taking several steps to combat different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also doesn’t necessarily indicate the multi-coated lens is much better than a single coated lens. Being “much better” hinges on the maker’s lens treatment technology and the quality of glass used in constructing the rifle glass.
Anti-water Lens Coating
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Alternatives for Installing Rifle Scopes on Firearms
Mounting solutions for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which permit rifle shooters to rapidly install and dismount the optics.
Hex Key Rifle Glass Rings
Standard, clamp design 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is wonderful 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 Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. A wide range of 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 tightly to a flat top type 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 preserving accuracy. These types of mounts are useful and convenient for shooting platforms which are carried a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can wreck a day on the range and your costly optic by triggering fogging and making residue within the scope tube. The majority of optics prevent humidity from getting in the optical tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard a watercraft and are concerned about the optic still functioning if it is submerged in water and you can still find the firearm.
About Rifle Glass Tube Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less influenced by condition changes and pressure variations from the outdoor environment which could possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
