Rifle Optic Details
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account different natural things like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have around eleven parts which are arranged within and outside of the scope. These parts include the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the perfect type of rifle optic is based around what type of shooting you plan on doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the level of zoom being used. The result 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 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minor
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the same overall size in relation to the quantity of zoom being used. The final result is that the reticle measurements alter based upon the zoom applied to shoot over longer distances given that the reticle markings present distinct increments which differ with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular types of scopes are beneficial for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who desire a clearer optic sight picture without space used up by the enlarged FFP reticle
Magnification for Rifle Optics
The extent of scope zoom you need is based on the kind of shooting you intend to do. Almost every style of rifle optic supplies some degree of zoom. The quantity of magnification a scope gives is established by the dimension, thickness, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Info About Single Power Lens Glass
A single power rifle optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate considering that it is a fixed power optic.
Variable Power Lens Scope Info
Variable power rifle scopes can be modified between magnified levels. The power adjustment is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some suggested scope power settings and the ranges where they may be efficiently used. Highly magnified optics will not be as useful as lower magnification scopes because too much magnification can be a bad thing. The same concept applies to extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Info on Rifle Glass Lens Covering
All modern rifle scope lenses are covered in special coatings. There are different types and qualities of lens coatings. When considering luxury rifle targeting setups, Lens finishing can be a significant component of defining the rifle’s capability. The glass lenses are one of the most key pieces of the optic because they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses safeguards the lens surface area as well as helps with anti glare capabilities from refracted direct sunlight and color perception.
HD Versus ED Lenses
Some glass companies even use “HD” or high-def glass finishings that use different processes, elements, polarizations, and chemical applications to enhance different colors and viewable definition through lenses. This high-definition coating is normally used with increased density glass which lowers light’s ability to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over items with hard shapes as light hits the item from various angles.
Single Coating Versus Multi-Coating
Different scope lenses can also have various coatings applied to them. All lenses normally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” covered. This means the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can show that a maker is taking numerous steps to fight various natural elements like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily indicate the multi-coated lens is better than a single layered lens. Being “better” depends upon the producer’s lens treatment technology and the quality of materials used in creating the rifle optic.
Anti-water Glass Lens Finishing
Water on an optic’s lens does not improve maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface area of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Options for Mounting Rifle Scopes on Firearms
Installing solutions for scopes come in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release variations which use throw levers which permit rifle operators to rapidly install and remove the optics.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount 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 abuse the rifle takes.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles.
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of optics protect against moisture from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity avoidance for conventional use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the scope still performing if it is submerged in water and you can still rescue the gun.
Gas Purged Rifle Scope Tubes
Another element of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less altered by climate changes and pressure differences from the outdoor environment which could possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
