Rifle Optic Facts
Rifle scopes enable you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be adjusted to account for different environmental factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have about 11 parts which are arranged within and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair is located in relation to the scopes zoom. It simply suggests the reticle is behind or in front of the magnification lens of the scope. Considering the very best style of rifle scope is dependent on what sort of shooting you anticipate undertaking.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their target “hold over” and also “lead” equations for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature 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 reticle measurement.
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic sight picture without area used up by the larger size FFP reticle
Details on Rifle Optic Zoom
The amount of zoom a scope supplies is determined 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.
Single Power Lens Rifle Scope Info
A single power rifle scope or optic will have a zoom number designator like 4×32. This implies the magnification 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 a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes use variable power levels. The power modification is accomplished 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 Scopes
Here are some suggested scope power settings and the ranges where they could be successfully used. Highly magnified optics will not be as beneficial as lower magnification rifle scope glass given that too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to longer distances where the shooter needs to have increased power to see where to properly aim the rifle.
Rifle Scope Lens Coating
All modern-day rifle scope lenses are covered in special coatings. There are various types and qualities of coatings. Lens finish can be an essential aspect of a rifle when looking at high end rifle optics and targeting equipment. The lenses are one of the most critical components of the optic considering that they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens exterior and improves anti glare capabilities from refracted direct sunlight and color discernibility.
HD Versus ED Lenses
Some rifle scope makers also use “HD” or high-definition lense coatings which apply various procedures, elements, rare earth compounds, and polarizations to draw out separate color ranges and viewable target visibility through the lens. This HD coating is normally used with greater density glass which reduces light’s opportunity to refract through the lens glass. Some scope producers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be visible around objects with defined shapes as light hits the item from particular angles.
Rifle Optic Lens Single Finish Versus Multi-Coating
Various optic lenses can likewise have different finishings applied to them. All lenses generally have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope designer and how much money you spent paying for it. Both are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has multiple treatments applied to the surfaces. If a lens gets numerous treatments, it can prove that a producer is taking numerous steps to combat different environmental elements like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally does not necessarily imply the multi-coated lens is better than a single covered lens. Being “better” is dependent on the maker’s lens treatment innovation and the quality of materials used in building the rifle optic.
Anti-water Lens Finishes
Water on a scope lens does not help with retaining a clear sight picture through an optic in any way. Many top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for 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 slide off of the scope to preserve a clear, water free sight picture.
Optic Installing Alternatives
Installing options for scopes come in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use toss levers which allow rifle shooters to quickly mount and dismount 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is perfect for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day on the range and your costly optic by resulting in fogging and producing residue within the scope tube. A lot of optics prevent moisture from entering the optical tube with a system of sealing O-rings which are water resistant. Normally, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity prevention for conventional use rifles, unless you intend on taking your rifle on boats and are worried about the scope still functioning if it is submerged in water and you can still find the rifle.
Info Around Rifle Optic Tube Gas Purging
Another element of avoiding the buildup of wetness 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 scope is less affected by condition alterations and pressure distinctions from the outdoor environment which might potentially 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.
