Scope Facts
Rifle scopes allow you to specifically aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses within the scope. The scope’s alignment can be adapted to take into account varied ecological factors like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes and optics have around eleven parts which are arranged inside and outside of the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. See all eleven parts of a rifle optical system.
About Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has determines where the reticle or crosshair lies in relation to the optic’s zoom. It simply means the reticle is behind or ahead of the magnification lens of the optic. Picking the most reliable sort of rifle optic depends upon what style of shooting you plan on undertaking.
Info on First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their weapon
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. This causes the reticle to remain at the exact same dimensions relative to the level of zoom being used. The end result is that the reticle measurements shift based upon the zoom chosen to shoot over greater ranges since the reticle markings represent various increments which can vary with the zoom. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of scopes are handy for:
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who choose a clearer optic picture without space taken up by the larger sized FFP reticle
About Rifle Optic Zoom
The quantity of magnification a scope offers 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.
Single Power Lens Optics
A single power rifle optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust because it is a fixed power optic.
About Variable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a format like 2-10×32. These numbers mean the magnification of the scope can be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power modification is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope powers and the distances where they may be effectively used. Bear in mind that high magnification scopes and optics will not be as efficient as lower powered glass because increased magnification can be a negative thing in certain situations. The exact same concept relates to extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
Info on Rifle Glass Lens Finish
All modern rifle optic lenses are layered. There are various types and qualities of finishes. Lens finish can be an essential element of a rifle’s setup when considering high end rifle optics and scope equipment. The lenses are among the most vital components of the optic because they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface area and assists with anti glare from excess daylight and color profiles.
ED Versus HD Scopes
Some optic producers additionally use “HD” or high-def lense finishes which use different procedures, polarizations, rare earth compounds, and components to extract different color ranges and viewable target definition through lenses. This HD finishing is often used with increased density glass which reduces light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be visible around items with hard outlines as light hits the item from certain angles.
Single Optic Lens Finishing Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses usually have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing placed on it so that the lens will be efficiently usable in lots of types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This means the lens has had numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can prove that a producer is taking several actions to fight various natural elements like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also doesn’t always imply the multi-coated lens is much better than a single coated lens. Being “much better” is dependent on the producer’s lens treatment techniques and the quality of products used in building the rifle scope.
Anti-water Lens Finishing
Water on a scope’s lens does not help with keeping a clear sight picture through an optic whatsoever. Numerous top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the surface area of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Long Guns
Mounting approaches for scopes come in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to rapidly mount and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation 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 is developed for long range precision shooting. This type of scope install is great for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope 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. Several scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping precision. These types of mounts come in practical for shooting platforms which are moved a lot, to take off the scope from the rifle for protection, or for optics which are utilized in between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the optic is less affected by temp shifts and pressure distinctions from the outside environment which might possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
