Information About Rifle Optics
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s alignment can be adjusted to account for numerous natural elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing 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 about 11 parts which are arranged internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other components. Learn about the eleven parts of rifle glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who know their aim point “hold over” as well as “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. 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.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who would like a clearer optic picture without space used up by the bigger FFP reticle
Magnification for Rifle Optics
The level of scope zoom you need depends on the style of shooting you want to do. Just about every type of rifle glass offers some level of zoom. The quantity of magnification a scope provides is identified by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the glass. This denotes what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Info on Single Power Lens Rifle Scopes
A single power rifle scope and optic uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is fixed.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a format like 2-10×32. These numbers imply the magnification of the scope can be changed in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power shift is achieved by applying the power ring component of the scope near the rear of the scope by the eye bell.
Optic Power and Ranges
Here are some suggested scope powers and the ranges where they can be efficiently used. Bear in mind that high power scopes will not be as practical as lower magnification level glass since too much magnification can be a bad thing. The exact same idea goes for longer ranges where the shooter needs increased power to see exactly where to best aim the rifle.
Scope Lens Finishing
All present day rifle scope lenses are layered. Lens covering is a significant element of a shooting platform when buying high end rifle optics and scope equipment.
Info on Scope Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use various techniques, chemicals, polarizations, and components to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Rifle Glass
Different optic lenses can also have different finishings applied to them. All lenses generally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful 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 makers also make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Scope Lens Hydrophobic Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and premium scope producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Rifle Optic Installing Options
Mounting solutions for scopes come in a few options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally are made in quick release versions which use throw levers which enable rifle operators to rapidly install and remove the scopes.
Scope Mounting Solutions with Hex Key Rings
Standard, clamp style 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 are developed for long range precision shooting. This type of scope install is wonderful for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts are useful and handy for shooting platforms which are transported a lot, to remove the optic from the rifle for protection, or for sight systems which are used between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by inducing fogging and making residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a series of sealing O-rings which are water resistant. Normally, these water resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity avoidance for basic use rifles, unless you intend on taking your rifle on your motorboat and are worried about the optic still functioning if it goes overboard and you can still find the gun.
Optic Gas Purging
Another part of avoiding the buildup of moisture inside of 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 optic is less altered by temp alterations and pressure distinctions from the external environment which may potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
