What You Need to Know About Scopes
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through zoom by employing a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account various natural aspects like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have about eleven parts which are located within and outside of the scope body. These parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. Learn about the eleven parts of glass.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located relative to the optic’s zoom. It simply implies the reticle is behind or in front of the magnification lens of the scope. Picking out the most beneficial form of rifle glass depends upon what style of hunting or shooting you anticipate undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who have an idea for their target “hold over” and also “lead” correlations for their long guns
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within shorter ranges and proximities
- Shooters who like a clearer optic sight picture with less room taken up by the larger size FFP reticle
Rifle Glass Zoom
The extent of scope zoom you require depends upon the type of shooting you want to do. Practically every style of rifle glass offers some level of zoom. The amount of magnification a scope supplies is identified by the dimension, density, and curvatures of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This suggests what the shooter is looking at through the scope is amplified times the power aspect of what can normally be seen by human eyes.
About Fixed Single Power Lens Optics
A single power rifle optic comes with a magnification number designator like 4×32. This implies 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 because it is a fixed power scope.
About Adjustable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification level in a format like 2-10×32. These numbers suggest the zoom of the scope could be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is achieved by working with the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Scopes
Here are some recommended scope powers and the ranges where they could be effectively used. Bear in mind that higher magnification optics and scopes will not be as efficient as lower magnification level scopes due to the fact that increased magnification can be a bad thing. The exact same concept goes for extended ranges where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
Info on Lens Finish
All modern rifle optic lenses are covered. Lens finishing can be a vital element of a rifle system when considering high end rifle optics and scope equipment.
Details on Optic Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens coverings which use various processes, elements, polarizations, and chemicals to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses usually have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finishing placed on it so that it will be optimally functional in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope producer and the amount you spent for it. Both the make and cost are signs of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can establish that a producer is taking multiple steps to combat different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally does not necessarily suggest the multi-coated lens will perform much better than a single layered lens. Being “better” depends on the maker’s lens treatment innovation and the quality of components used in creating the rifle glass.
Anti-water Rifle Optic Lens Finish
Water on a lens does not improve maintaining a clear sight picture through an optic in any way. Lots of top of the line and premium scope makers 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 of the Steiner scope lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Mounting approaches for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the scopes.
Hex Key Glass Rings
Standard, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on 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 far away accuracy shooting. This kind of scope mount is excellent for rifle systems which need a long lasting, rock solid mount which will not change no matter just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a specialized scope setup on a long distance hunting or interdiction firearm which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screws from backing out after they are installed firmly in position. An example of these rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These types 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 style mount, a number of scopes can also be swapped out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely 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 preserving the original sighting settings. These kinds of mounts are useful and practical for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for aiming systems which are adopted between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your costly optic by resulting in fogging and making residue inside of the scope tube. Most scopes protect against humidity from entering the optical tube with a system of sealing O-rings which are waterproof. Generally, these water resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are worried about the optic still performing if it is submerged in water and you can still recover the rifle.
Gas Purged Rifle Glass Tubes
Another part of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less influenced by condition changes and pressure variations from the external environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
