Facts About Rifle Optics
Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification using a series of lenses inside the scope. The scope’s positioning can be adapted to account for separate environmental aspects like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon 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 contemporary rifle scopes and optics have around eleven parts which are arranged within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
About Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair lies in relation to the optic’s zoom. It actually implies the reticle is located behind or before the magnifying lens of the scope. Deciding on the most desired kind of rifle optic depends on what style of shooting or hunting you anticipate undertaking.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who understand their target “hold over” plus “lead” ratios for their rifles
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnification lens. This triggers the reticle to stay at the exact same scale in relation to the volume of magnification being used. The effect is that the reticle measurements adapt based on the zoom employed to shoot over greater ranges due to the fact that the reticle markings present different increments which change 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 types of optics work for:
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who choose a clearer optic sight picture without area used up by the larger sized FFP reticle
Rifle Scope Magnification
The quantity of magnification a scope offers is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Details
A single power rifle scope or optic will have a zoom number designator like 4×32. This implies 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 since it is fixed.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes use enhanced power. The power adjustment is achieved using 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 suggested scope power levels and the ranges where they could be successfully used. Keep in mind that higher power optics will not be as efficient as lower magnification level scope and optics since excessive magnification can be a negative thing in certain situations. The same idea goes for longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle.
Rifle Optic Lens Finishing
All modern-day rifle scope and optic lenses are coated. There are different types and qualities of glass lens coverings. When shopping for high end rifle optical setups, Lens coating can be an important component of defining the capability of the rifle. The lenses are one of the most significant parts of the glass as they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses shields the lens surface and also assists with anti glare capabilities from refracted sunlight and color visibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishings which use various methods, chemicals, polarizations, and elements to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Rifle Glass Lens Finishing Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It must have a finishing applied to it so that it will be efficiently usable in lots of types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to 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 layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Anti-water Lens Finishing
Water on a scope lens does not support preserving a clear sight picture through an optic whatsoever. Many top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Scope Mounting Alternatives
Installing options for scopes come in a few 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 normally can be found in quick release variations which use manual levers which enable rifle operators to quickly install and dismount the scope.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This kind of scope mount is effective for rifles which are in need of a long lasting, unfailing mount which will not change no matter how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a dedicated optics system on a reach out and touch someone hunting or competition rifle that will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to protect against the hex screw threads from backing out after they are installed securely in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off 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 style mount. These types of mounts are convenient for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another component of avoiding the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the glass is less altered by temperature alterations and pressure distinctions from the outdoor environment which might possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
