Rifle Glass Info
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom using a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account many natural things like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around eleven parts which are arranged inside and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. See all eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies in regard to the optic’s magnifying adjustments. It simply suggests the reticle is behind or ahead of the magnifying lens of the scope. Considering the most ideal style of rifle scope depends on what style of shooting or hunting you intend on undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who know their target “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This induces the reticle to remain at the exact same dimensions in connection with the volume of zoom being used. The result is that the reticle dimensions shift based on the magnification applied to shoot over longer distances due to the fact that the reticle markings represent distinct increments which fluctuate with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular types of scopes are beneficial for:
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who desire a clearer optic sight picture without room taken up by the bigger FFP reticle
Rifle Optic Zoom
The quantity of scope zoom you need depends on the kind of shooting you wish to do. Virtually every kind of rifle glass provides some amount of zoom. The quantity of zoom a scope provides is determined by the dimension, thickness, and curvatures of the lens glass within the rifle scope. The magnification level of the scope is the “power” of the glass. This signifies what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Fixed Single Power Lens Optic Info
A single power rifle optic uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust since it is fixed.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification levels. It will note the magnification amount in a configuration like 2-10×32. These numbers mean the zoom of the scope can be changed in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power adaptation is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Optics
Here are some recommended scope power levels and the ranges where they can be efficiently used. Highly magnified scopes will not be as beneficial as lower magnification level glass because too much magnification can be a negative aspect depending on your shooting distance. The same relates to extended distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
About Scope Lens Coverings
All present day rifle optic and scope lenses are layered. Lens covering can be an essential element of a shooting platform when buying high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens coverings which use various processes, aspects, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can likewise have different coverings applied to them. All lenses generally have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope maker and the amount you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Lens Coatings
Water on an optic’s lens does not support keeping a clear sight picture through a scope whatsoever. Lots of top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Rifle Optics on Firearms
Mounting solutions for scopes come in a few options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically are made in quick release versions which use manual levers which permit rifle operators to rapidly install and remove the optics.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style 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 are developed for long distance precision shooting. This type of scope install is great for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove 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 design mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day of shooting and your highly-priced optic by resulting in fogging and creating residue within the scope tube. Many scopes prevent humidity from going into the optical tube with a system of sealing O-rings which are water resistant. Normally, these water resistant optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity prevention for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on a boat and are worried about the scope still performing if it goes over the side and you can still recover the rifle.
Rifle Scope Gas Purging
Another element of preventing the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the optic is less influenced by condition shifts and pressure differences from the outside environment which may possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
