Rifle Scope Information
Rifle scopes enable you to exactly aim a rifle at various 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 alignment can be adjusted to take into account varied environmental aspects like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have around eleven parts which are arranged inside and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located in regard to the optic’s magnification. It simply indicates the reticle is situated behind or before the magnifying lens of the optic. Selecting the most desired style of rifle optic depends on what style of shooting you plan on doing.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) include the reticle behind the zoom lens. This causes the reticle to remain at the exact same overall size in connection with the volume of magnification being used. The outcome is that the reticle measurements alter based upon the magnification chosen to shoot over longer ranges considering that the markings represent different increments which can vary with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These kinds of optics work for:
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who select a clearer optic sight picture with less room used up by the bigger FFP reticle
The extent of scope zoom you need on your scope depends on the sort of shooting you intend to do. Pretty much every style of rifle glass offers some degree of zoom. The amount of zoom a scope provides is established by the size, density, and curves of the lenses within the rifle scope. The magnification level of the scope is the “power” of the glass. This denotes what the shooter is aiming at through the scope is magnified times the power factor of what can normally be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle optic or scope comes with a zoom 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 type of scope can not change considering that it is a fixed power optic.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified levels. 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.
The Power and Range of Scopes
Here are some recommended scope power levels and the distances where they can be effectively used. High power optics will not be as effective as lower magnification scopes considering too much magnification can be a bad thing. The same idea applies to extended ranges where the shooter needs adequate power to see where to properly aim the rifle at the target.
Optic Lens Covering
All modern-day rifle scope and optic lenses are layered. Lens coating can be an essential aspect of a shooting platform when thinking about high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some optic manufacturers will also use “HD” or high-def glass finishes which use various processes, rare earth compounds, elements, and polarizations to extract various color ranges and viewable target visibility through lenses. This high-definition finish is often used with higher density glass which decreases light’s chance to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around items with hard edges and outlines as light hits the object from particular angles.
Single Scope Lens Coating Versus Multi-Coating
Various optic lenses can likewise have different coverings applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope designer and how much money 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 define if their optic lenses are layered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can prove that a manufacturer is taking multiple steps to combat various environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not always imply the multi-coated lens will perform better than a single coated lens. Being “better” depends on the producer’s lens treatment solutions and the quality of glass used in developing the rifle scope.
Glass Lens Hydrophobic Finishing
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Scope Mounting Alternatives
Mounting options for scopes can be found in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use toss levers which enable rifle shooters to rapidly install and remove the optics.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp-on style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This form of scope mount is ideal for rifles which need a durable, rock solid mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a devoted scope system on a long distance scouting or competition rifle which will hardly ever need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screws from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a similar design mount. These types of mounts come in handy for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Glass Tube Gas Purging
Another part of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less impacted by temp alterations and pressure distinctions from the outdoor environment which might possibly allow water vapor to permeate 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.
