Info Rifle Scopes
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by using a set of lenses within the scope. The scope’s positioning can be adapted to account for different ecological things like wind and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around 11 parts which are arranged inside and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has decides where the reticle or crosshair is located in connection with the scopes zoom. It actually indicates the reticle is located behind or before the magnification lens of the optic. Looking for the most effective style of rifle optic is dependent on what variety of shooting or hunting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who desire a clearer optic picture with less room used up by the larger size FFP reticle
About Rifle Optic Zoom
The quantity of magnification a scope provides is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Power Lens Optics
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate because it is fixed.
Info on Variable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification amount in a format like 2-10×32. These numbers indicate the zoom of the scope could be changed in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power adaptation is achieved by operating the power ring part of the scope near the back of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some recommended scope power levels and the ranges where they may be effectively used. Always remember that high magnification glass will not be as efficient as lower magnification level glass since increased zoom can be a bad thing. The very same idea applies to extended distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle.
Info on Lens Coating
All modern rifle optic and scope lenses are coated. There are various types and qualities of glass lens finishes. When looking at luxury rifle scope systems, Lens coating can be a vital element of defining the capability of the rifle. The glass lenses are among the most vital pieces of the optic because they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens surface area and even helps with anti glare capabilities from excess sunlight and color presence.
ED Versus HD Glass
Some rifle glass companies even use “HD” or high-definition glass coverings that take advantage of different procedures, rare earth compounds, aspects, and polarizations to extract numerous color ranges and viewable target visibility through lenses. This high-def finishing is often used with more costly, high density glass which drops light’s ability to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be obvious over items with defined shapes as light hits the object from certain angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can also have various coverings used to them. All lenses typically have at least some type of treatment or finishing used 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 safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope producer and how much you spent for it. The scope’s maker and cost are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has had multiple treatments applied to them. If a lens gets several treatments, it can establish that a producer is taking several actions to combat different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not necessarily indicate the multi-coated lens is much better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle glass.
Optic Lens Hydrophobic Finishing
Water on a scope’s lens doesn’t support keeping a clear sight picture through a scope in any way. Many top of the line and high-end scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the surface area of the Steiner scope lens so the H2O particles 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.
Choices for Mounting Glass on Firearms
Mounting approaches for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also typically come in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the scope.
Hex Key Scope Ring Mounting Solutions
Standard, clamp style mounting optic rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of independent rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This form of scope mount is effective for rifles which require a durable, unfailing mount which will not shift despite how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a dedicated optics setup on a reach out and touch someone hunting or hard target interdiction long gun that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from wiggling out after they are installed securely in place. An example of these rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. If they all use a comparable style mount, several scopes can also be switched on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts come in convenient for shooting platforms which are carried a lot, to remove the optic from the rifle for protection, or for aiming systems which are chosen for use between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Most scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Scope Tubes
Another part of preventing the buildup of moisture within the rifle optic’s 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 condition changes and pressure distinctions from the external environment which could possibly allow 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.
