Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be adapted to account for separate ecological considerations like wind and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle optics have around 11 parts which are found within and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has decides where the reticle or crosshair is located in regard to the scopes zoom. It actually suggests the reticle is located behind or ahead of the magnifying lens of the scope. Selecting the most effective style of rifle glass is based on what sort of shooting you anticipate undertaking.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the level of zoom being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who have an idea for their target “hold over” and also “lead” correlations for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This triggers the reticle to remain at the exact same scale in connection with the level of zoom being used. The result is that the reticle measurements evolve based upon the magnification employed to shoot over longer distances considering that the reticle markings represent various increments which vary with the magnification. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular kinds of optics are handy for:
- Far away forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who select a clearer optic picture without space taken up by the larger size FFP reticle
Zoom for Rifle Glass
The quantity of magnification a scope supplies is figured out 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.
Info About Fixed Power Lens Rifle Glass
A single power rifle scope and optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a fixed power optic.
Info on Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power change is accomplished by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some suggested scope powers and the distances where they could be successfully used. High power glass will not be as efficient as lower powered glass because too much zoom can be a negative aspect depending on your shooting distance. The same idea relates to extended distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle at the target.
Lens Finishing for Optics
All top teir rifle optic and scope lenses are layered. Lens finish is a vital aspect of a rifle when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some optic makers even use “HD” or high-def lense coatings which employ different procedures, elements, chemicals, and polarizations to extract various colors and viewable target visibility through the lens. This high-definition covering is commonly used with greater density glass which brings down light’s ability to refract through the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be visible around objects with well defined shapes as light hits the item from certain angles.
Single Coating Versus Multi-Coating
Various scope lenses can even have different finishings applied to them. All lenses usually have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It needs to have a finish put on it so that the lens will be optimally usable in numerous kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Coating for Optics
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Optic Installing Options
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use manual levers which permit rifle operators to quickly mount and dismount the optics.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transported a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles.
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by inducing fogging and creating residue within the scope’s tube. Many optics prevent humidity from entering the scope tube with a system 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 sufficient moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the scope still performing if it is submerged in water and you can still rescue the rifle.
Details on Optic Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less affected by temperature alterations and pressure distinctions from the outdoor environment which could possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
