Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account many environmental elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand exactly 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. Many contemporary rifle scopes have about eleven parts which are arranged within and externally on the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. See all eleven parts of a scope.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has identifies where the reticle or crosshair lies in regard to the optic’s magnifying adjustments. It literally means the reticle is located behind or in front of the magnifying lens of the scope. Picking out the very best type of rifle optic depends on what form of shooting you intend on undertaking.
About First Focal Plane Optics
First focal plane optics (FFP) come with the reticle before the magnifying lens. This causes the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are very little
- Experienced shooters who know their aim point “hold over” and also “lead” equations for their long guns
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) feature the reticle behind 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 measurement.
- Far away kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots happen within shorter distances and ranges
- Shooters who select a clearer optic picture without area used up by the larger size FFP reticle
Zoom for Rifle Optics
The extent of scope zoom you need is based on the sort of shooting you would like to do. Just about every kind of rifle optic provides some degree of magnification. The quantity of magnification a scope supplies is determined by the diameter, thickness, and curves of the lenses inside of the rifle scope. The magnifying level of the optic is the “power” of the glass. This indicates what the shooter is aiming at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Single Power Lens Optics
A single power rifle scope will have a magnification 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 since it is a fixed power optic.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification levels. It will note the zoom level in a format such as 2-10×32. These numbers indicate the magnification of the scope could be changed in between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some suggested scope power levels and the ranges where they could be successfully used. Remember that higher magnification glass will not be as efficient as lower magnification level glass due to the fact that too much magnification can be a bad thing. The same concept relates to longer ranges where the shooter needs enough power to see precisely where to best aim the rifle.
About Lens Finishes
All modern rifle scope lenses are layered. There are different types and qualities of lens coatings. Lens coating is a crucial element of a rifle when looking into luxury rifle optics and scope units. The lenses are among the most essential parts of the optic because they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface and even helps with anti glare from refracted natural light and color exposure.
Details on Rifle Scope Lens Coatings – HD Versus ED
Some glass producers will also use “HD” or high-definition lense finishes that employ different procedures, rare earth compounds, aspects, and polarizations to draw out various color ranges and viewable target visibility through the lens. This high-definition coating is frequently used with more costly high density glass which decreases light’s capability to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard edges and shapes as light hits the item from particular angles.
Rifle Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can likewise have different finishes used to them. All lenses usually have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to 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 coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to them. If a lens receives numerous treatments, it can show that a maker is taking several actions to fight different environmental factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally doesn’t always suggest the multi-coated lens is better than a single layered lens. Being “better” depends upon the manufacturer’s lens treatment solutions and the quality of products used in constructing the rifle glass.
Hydrophobic Lens Coatings
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Options for Installing Glass on Long Guns
Installing approaches for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use manual levers which permit rifle shooters to quickly install and remove the glass.
Hex Key Glass Ring Mounts
Normal, clamp design 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 designed for long distance precision shooting. This type of scope install is fine for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable design 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 connect nicely to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These kinds of mounts come in convenient for shooting platforms which are moved around a lot, to take off the optic from the rifle for protection, or for optics which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle glass can ruin a day on the range and your highly-priced optic by resulting in fogging and making residue within the scope’s tube. Most scopes prevent humidity from getting in the scope tube with a series of sealing O-rings which are water resistant. Generally, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for basic use rifles, unless you anticipate taking your rifle aboard watercrafts and are worried about the scope still working if it is submerged in water and you can still recover the gun.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less affected by condition alterations and pressure differences from the external environment which could possibly permit water vapor to permeate 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.
