What You Need to Know About Rifle Scopes
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 zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted to take into account many ecological considerations like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes have about eleven parts which are found inside and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other elements. See all eleven parts of optics.
About Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has identifies where the reticle or crosshair lies in connection with the scopes magnification. It literally means the reticle is located behind or before the magnifying lens of the scope. Picking out the most beneficial kind of rifle glass depends upon what type of shooting or hunting you plan on undertaking.
First Focal Plane Optics
First focal plane glass (FFP) include the reticle before the magnification lens. This triggers 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 enhanced distance as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are low
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who prefer a clearer optic picture without room used up by the larger sized FFP reticle
Ins and Outs of Rifle Glass Zoom
The quantity of magnification a scope supplies is identified by the size, density, 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 Info
A single power rifle optic or scope comes with a magnification 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 kind of scope can not adjust because it is a fixed power optic.
Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the zoom degree in a configuration like 2-10×32. These numbers imply the zoom of the scope can be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Glass Power Level and Ranges
Here are some suggested scope powers and the distances where they can be successfully used. Consider that higher power scopes and optics will not be as efficient as lower powered optics and scopes since excessive magnification can be a detractor. The very same idea goes for longer distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
About Lens Covering
All contemporary rifle scope and optic lenses are coated. Lens finishing is an important aspect of a shooting system when looking at high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some optic suppliers will also use “HD” or high-def lense coatings that make the most of different procedures, aspects, chemical substances, and polarizations to extract separate colors and viewable target visibility through lenses. This high-definition finish is often used with more costly, high density lens glass which lowers light’s ability to refract through the lens glass. Some scope corporations use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around things with hard shapes as light hits the item from particular angles.
Details on Single Covering Versus Multi-Coating
Various optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
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 covered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had multiple treatments applied to the surfaces. If a lens gets several treatments, it can establish that a maker is taking multiple steps to fight different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not always indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the maker’s lens treatment technology and the quality of products used in developing the rifle glass.
Anti-water Covering for Rifle Scopes
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water finishing.
Choices for Installing Rifle Glass on Long Guns
Installing options for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release variations which use toss levers which permit rifle operators to rapidly install and dismount the scope.
Hex Key Scope Rings
Normal, 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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope install is wonderful 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.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. Multiple scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top type 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 preserving accuracy. These kinds of mounts come in convenient for rifles which are transferred a lot, to take off the glass from the rifle for protection, or for optics which are utilized in between several rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day on the range and your highly-priced optic by triggering fogging and developing residue within the scope’s tube. The majority of scopes protect against humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Normally, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are worried about the optic still functioning if it goes over the side and you can still recover the gun.
Gas Purged Rifle Glass Tubes
Another element of preventing the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the scope is less affected by condition alterations and pressure differences from the outdoor environment which could possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
