Rifle Scope Facts
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by using a set of lenses within the scope. The scope’s positioning can be adjusted to take into account different ecological elements like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes and optics have around eleven parts which are found inside and outside of the scope. These parts include the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has decides where the reticle or crosshair lies in relation to the scopes magnification. It literally implies the reticle is behind or ahead of the magnification lens of the scope. Deciding upon the most ideal type of rifle glass is dependent on what variety of shooting you plan on undertaking.
First Focal Plane Glass Details
First focal plane optics (FFP) feature the reticle before the magnifying lens. This causes the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are small
- Experienced shooters who understand their target “hold over” plus “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) feature the reticle behind the zoom 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 occur within shorter proximities and ranges
- Shooters who like a clearer optic picture without area used up by the larger size FFP reticle
Rifle Scope Zoom
The quantity of scope zoom you need on your glass is based on the sort of shooting you wish to do. Pretty much every style of rifle optic supplies some amount of zoom. The amount of magnification a scope delivers is established by the size, density, and curves 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 amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Glass
A single power rifle optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate because it is a set power scope.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the zoom amount in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be adjusted between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power modification is accomplished by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some advised scope power settings and the distances where they may be successfully used. High power optics will not be as efficient as lower powered scopes due to the fact that too much zoom can be a bad thing. The exact same idea relates to longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Rifle Glass Lens Finish
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of glass lens finishes. Lens covering is an important aspect of a rifle’s setup when contemplating high-end rifle optics and scope units. The lenses are one of the most vital components of the scope given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface as well as assists with anti glare from excess sunshine and color perception.
About Lens Coatings – HD Versus ED
Some rifle glass manufacturers additionally use “HD” or high-def glass finishes which apply various processes, polarizations, chemicals, and components to extract different color ranges and viewable target definition through lenses. This high-def covering is often used with more costly high density lens glass which drops light’s chance to refract through the lens glass. Some scope corporations use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often visible over objects with well defined outlines as light hits the object from specific angles.
Single Covering Versus Multi-Coating
Different optic lenses can also have different finishes used to them. All lenses normally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope designer and the amount you paid for it. The scope’s maker and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can establish that a producer is taking several steps to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This additionally does not always mean the multi-coated lens is better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of components used in creating the rifle scope.
Anti-water Rifle Scope Lens Covering
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic anti-water finish.
Glass Installing Choices
Mounting options for scopes are available in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use toss levers which permit rifle operators to quickly mount and dismount the scopes.
Hex Key Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope mount is great for rifles which require a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between several rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your highly-priced optic by triggering fogging and generating residue within the scope’s tube. Most scopes prevent moisture from getting in the scope tube with a series of sealing O-rings which are waterproof. Typically, these optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for basic use rifles, unless you anticipate taking your rifle aboard watercrafts and are concerned about the scope still functioning if it is submerged in water and you can still salvage the gun.
What to Know About Scope Tube Gas Purging
Another component of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the glass is less impacted by climate alterations and pressure differences from the outside environment which might possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
