What You Need to Know About Rifle Scopes
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target at range. They do this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adjusted to account for different natural factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have about 11 parts which are located internally and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other components. Learn about the eleven parts of scopes.
About Rifle Glass Styles
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 lies in regard to the optic’s magnification. It simply indicates the reticle is behind or in front of the magnification lens of the scope. Choosing the most beneficial form of rifle glass is based on what kind of shooting you intend on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards by using 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who have an idea for their target “hold over” and “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This causes the reticle to stay at the very same size in connection with the quantity of zoom being used. The result is that the reticle dimensions evolve based on the magnification used to shoot over greater distances given that the reticle measurements present various increments which can vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular kinds of optics work for:
- Far away types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who want a clearer optic picture with less room taken up by the bigger FFP reticle
The quantity of zoom a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Scope Info
A single power rifle scope or optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is a set power scope.
Info on Adjustable Power Lens Optics
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the zoom level in a format such as 2-10×32. These numbers imply the zoom of the scope could be adjusted between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power manipulation is accomplished by applying the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some suggested scope power settings and the distances where they could be effectively used. High power scopes will not be as beneficial as lower magnification level rifle scope glass considering too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to longer ranges where the shooter needs sufficient power to see where to best aim the rifle.
Scope Lens Covering
All modern-day rifle scope lenses are covered. Lens coating is a vital element of a shooting system when purchasing high end rifle optics and scope setups.
About Lens Coatings – HD Versus ED
Some rifle glass makers also use “HD” or high-def lense coatings that use different procedures, polarizations, elements, and chemicals to draw out separate colors and viewable definition through lenses. This high-definition covering is typically used with greater density lens glass which decreases light’s ability to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often visible over objects with hard edges and shapes as light hits the item from certain angles.
Single Finish Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have different finishes used to them. All lenses normally 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 decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coating
Water on a scope lens does not assist with preserving a clear sight picture through an optic whatsoever. Numerous top of the line and premium scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface area of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Options for Installing Rifle Optics on Long Guns
Installing approaches for scopes can be found in a few options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use throw levers which allow rifle operators to quickly install and remove the optics.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope mount is fine for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass 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. Multiple scopes can also be switched out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
Details on Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your highly-priced optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these water resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough humidity prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still performing if it goes overboard and you can still find the rifle.
What to Know About Rifle Glass Tube Gas Purging
Another part of avoiding the buildup of wetness 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 scope is less altered by condition alterations and pressure variations from the outside environment which could possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
