Optic Information
Rifle scopes enable you to exactly align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses inside the scope. The scope’s alignment can be dialed in to account for numerous environmental elements like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle optics have around eleven parts which are arranged inside and externally on the optic. These parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has decides where the reticle or crosshair lies relative to the scopes zoom. It simply means the reticle is behind or ahead of the magnifying lens of the optic. Choosing the most effective kind of rifle optic is dependent on what kind of hunting or shooting you intend on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (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 kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who would like a clearer optic picture without room used up by the larger size FFP reticle
Ins and Outs of Rifle Optic Zoom
The extent of scope zoom you require depends upon the type of shooting you wish to do. Pretty much every kind of rifle optic delivers some amount of zoom. The level of magnification a scope supplies is determined by the diameter, thickness, and curves of the lenses inside of the rifle optic. The zoom of the optic is the “power” of the opic. This indicates what the shooter is observing through the scope is magnified times the power element of what can normally be seen by human eyes.
Info on Fixed Single Power Lens Glass
A single power rifle scope will have 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 change considering that it is set from the factory.
Variable Power Lens Optic Details
Variable power rifle scopes can be modified between magnified settings. The power modification is performed by making use of 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 may be successfully used. Bear in mind that higher power scopes and optics will not be as effective as lower magnification level glass because too much zoom can be a detractor. The same applies to extended distances where the shooter needs increased power to see precisely where to best aim the rifle.
Lens Covering for Optics
All modern rifle scope lenses are layered. There are different types and qualities of lens finishings. When thinking about high end rifle targeting systems, Lens finish can be an essential component of a rifle. The glass lenses are one of the most critical pieces of the glass considering they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens surface and even assists with anti glare capabilities from refracted sunrays and color presence.
Info on Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens finishes which use various processes, aspects, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different coverings used to them. All lenses usually have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Optic Lens Covering
Water on an optical lens doesn’t support keeping a clear sight picture through an optic at all. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Options for Mounting Scopes on Firearms
Installing approaches for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release variations which use toss levers which enable rifle operators to quickly install and remove the optics.
Rifle Glass Mounting Solutions with Hex Key Rings
Basic, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use double individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is excellent for rifle systems which are in need of a resilient, rock solid mount which will not change despite how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a dedicated scope system on a reach out and touch someone hunting or hard target interdiction long gun which will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screw threads from backing out after they are mounted tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day on the range and your pricey optic by resulting in fogging and making residue within the scope tube. The majority of scopes protect against wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, these optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are concerned about the optic still working if it falls overboard and you can still rescue the rifle.
Glass Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less impacted by temperature level alterations and pressure variations from the outside environment which may possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
