Info Rifle Scopes
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a series of lenses within the scope. The scope’s alignment can be adjusted for the consideration of many natural considerations like wind and elevation increases or decreases 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 via the scope as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have about 11 parts which are located within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, elevation turrets, focus rings, and other elements. Learn about the eleven parts of rifle glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the best type of rifle optic is based on what type of shooting you plan on doing.
About First Focal Plane Glass
First focal plane optics (FFP) include the reticle before the magnification lens. This causes the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who know their target “hold over” plus “lead” correlations for their rifles
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This triggers the reticle to stay at the same scale in connection with the quantity of magnification being used. The final result is that the reticle dimensions evolve based on the magnification applied to shoot over greater ranges because the markings present various increments which fluctuate with the zoom. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular sorts of glass are useful for:
- Far away types of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who want a clearer optic sight picture with less room used up by the larger sized FFP reticle
Details on Rifle Scope Magnification
The level of scope zoom you need on your scope depends upon the sort of shooting you want to do. Nearly every style of rifle optic delivers some level of magnification. The quantity of zoom a scope provides is established by the diameter, density, and curvatures of the lens glass inside of the rifle optic. The zoom of the scope is the “power” of the opic. This suggests what the shooter is looking at through the scope is amplified times the power factor of what can generally be seen by human eyes.
Fixed Power Lens Scope Facts
A single power rifle optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is a fixed power scope.
Info on Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power adjustment is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some advised scope powers and the ranges where they may be efficiently used. Highly magnified rifle scope glass will not be as beneficial as lower magnification level rifle scope glass considering too much magnification can be a bad thing. The same goes for longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.
Optic Lens Covering
All top of the line rifle glass lenses are covered. Lens finish can be a crucial element of a rifle system when looking into high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some optic suppliers additionally use “HD” or high-def glass coatings which employ various processes, polarizations, rare earth compounds, and components to enhance separate colors and viewable definition through lenses. This high-def covering is commonly used with higher density lens glass which drops light’s capability to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often obvious around objects with well defined shapes as light hits the item from particular angles.
Single Finishing Versus Multi-Coating
Different optic lenses can also have different coverings used to them. All lenses typically have at least some type of treatment or covering applied 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 enhancing multi-purpose treatment. This lens treatment can shield 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 upon the scope producer and how much you paid for it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has numerous treatments applied to them. If a lens gets numerous treatments, it can indicate that a manufacturer is taking numerous actions to fight different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally doesn’t necessarily mean the multi-coated lens will perform better than a single covered lens. Being “better” hinges on the manufacturer’s lens treatment innovation and the quality of glass used in constructing the rifle glass.
Hydrophobic Rifle Scope Lens Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic coating.
Alternatives for Installing Rifle Scopes on Long Guns
Installing solutions for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use throw levers which allow rifle operators to quickly install and dismount the glass.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is great for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a similar style mount, several scopes can often be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping accuracy. These kinds of mounts come in beneficial for shooting platforms which are transferred a lot, to take off the scope from the rifle for protection, or for optics which are chosen for use between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day of shooting and your pricey optic by inducing fogging and developing residue inside of the scope’s tube. Many optics prevent humidity from getting in the scope tube with a system of sealing O-rings which are waterproof. Generally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness prevention for conventional use rifles, unless you anticipate taking your rifle on a boat and are worried about the optic still working if it goes overboard and you can still retrieve the gun.
Rifle Scope Gas Purging
Another part of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less influenced by temperature alterations and pressure differences from the outside environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
