Rifle Scope Information
Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification using a series of lenses within the scope. The scope’s positioning can be adjusted to account for separate environmental elements like wind and elevation decreases to account 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 via the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have around 11 parts which are found inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the optimal type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Glass Info
First focal plane glass (FFP) come with the reticle before the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without space taken up by the enlarged FFP reticle
About Rifle Optic Magnification
The amount of magnification a scope offers is identified 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 Glass Details
A single power rifle scope comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope power settings and the distances where they could be effectively used. Remember that high power scopes will not be as efficient as lower powered optics since increased zoom can be a bad thing. The very same idea relates to longer distances where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Rifle Scope Lens Coating
All modern rifle scope lenses are layered. There are different types and qualities of glass finishings. Lens covering can be a crucial element of a rifle when contemplating luxury rifle optics and targeting systems. The lenses are one of the most significant components of the optic considering they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface area and also improves anti glare from excess direct sunlight and color perception.
About Glass Lens Coatings – HD Versus ED
Some glass producers will also use “HD” or high-def lense finishes which take advantage of different processes, polarizations, aspects, and chemicals to draw out a wide range of color ranges and viewable definition through the lens. This high-definition finish is typically used with greater density lens glass which decreases light’s chance to refract through the lens glass. Some scope vendors use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable around objects with hard outlines as light hits the item from particular angles.
Single Coating Versus Multi-Coating for Glass
Various optic lenses can also have different coatings used to them. All lenses generally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can show that a company is taking multiple steps to fight different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally doesn’t necessarily imply the multi-coated lens is better than a single coated lens. Being “better” depends on the maker’s lens treatment technology and the quality of components used in developing the rifle scope.
Hydrophobic Optic Lens Covering
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Rifle Scope Mounting Alternatives
Mounting approaches for scopes come in a few options. There are the basic scope rings which are separately mounted 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 toss levers which permit rifle shooters to quickly mount and remove the optics.
Hex Key Rifle Optic Ring Mounting Solutions
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 made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope install is wonderful for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. Several scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping accuracy. These kinds of mounts come in convenient for shooting platforms which are transferred a lot, to remove the scope from the rifle for protection, or for optics which are adopted in between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. Most scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less altered by condition alterations and pressure differences from the outdoor environment which might potentially enable 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.
