Rifle Scope Details
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 zoom by making use of a series of lenses inside the scope. The scope’s positioning can be adapted to take into account many environmental factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are arranged internally and outside of the optic. These optic pieces include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the best type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scopes
First focal plane optics (FFP) include the reticle before the zoom lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who know their target “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnification 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.
- Far away forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who select a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Zoom for Rifle Glass
The amount of scope magnification you need is based on the type of shooting you want to do. Just about every kind of rifle optic provides some level of magnification. The amount of zoom a scope delivers is established by the dimension, density, and curvatures of the lenses inside of the rifle scope. The magnification level of the optic is the “power” of the opic. This implies what the shooter is aiming at through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Single Power Lens Scopes
A single power rifle scope uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate considering that it is a fixed power scope.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power Level and Range Correlation
Here are some advised scope power levels and the distances where they can be effectively used. Remember that high power scopes and optics will not be as efficient as lower magnification level scope and optics because increased magnification can be a negative thing in certain situations. The same idea applies to extended distances where the shooter needs enough power to see where to properly aim the rifle at the target.
Info on Lens Finishing
All state-of-the-art rifle optic and scope lenses are coated. Lens coating can be a significant element of a shooting system when purchasing high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle glass producers also use “HD” or high-definition lens finishes which use various processes, rare earth compounds, elements, and polarizations to draw out different colors and viewable target definition through the lens. This HD finishing is frequently used with more costly high density lens glass which reduces light’s capability to refract by means of the lens glass. Some scope corporations 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 aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with defined shapes as light hits the object from various angles.
About Single Finish Versus Multi-Coating
Different scope lenses can also have various finishes applied to them. All lenses normally have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. This means the lens has several treatments applied to them. If a lens receives numerous treatments, it can indicate that a company is taking multiple steps to fight various natural elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally does not necessarily indicate the multi-coated lens will perform better than a single coated lens. Being “much better” is dependent on the producer’s lens treatment techniques and the quality of glass used in developing the rifle scope.
What to Know About Anti-water Finish
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic covering.
Rifle Optic Installing Choices
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use throw levers which permit rifle shooters to quickly install and remove the optics.
Optic Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This kind of scope mount is very good for rifle systems which need a durable, hard use mount which will not shift despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a faithful scope system on a far away hunting or competitors firearm that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to stop the hex screws from backing out after they are installed securely in place. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining accuracy. These types of mounts come in practical for shooting platforms which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are used between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day of shooting and your expensive optic by resulting in fogging and producing residue within the scope tube. A lot of optics protect against wetness from entering the optical tube with a system of sealing O-rings which are water resistant. Typically, these water resistant optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for basic use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it goes over the side and you can still find the gun.
Gas Purged Rifle Optic Tubes
Another component of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less altered by condition alterations and pressure differences from the outdoor environment which might possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
