What You Need to Know About Scopes
Rifle scopes permit you to specifically align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adjusted to take into account various environmental things like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes have about eleven parts which are found inside and externally on the optic. These parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the finest type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Optics
First focal plane glass (FFP) feature the reticle before the zoom lens. This induces 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 range as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who recognize their target “hold over” as well as “lead” ratios for their firearms
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same dimensions relative to the volume of zoom being used. The result is that the reticle measurements shift based upon the zoom employed to shoot over lengthier distances because the reticle measurements present different increments which can vary with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These kinds of glass work for:
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who desire a clearer optic sight picture with less area used up by the enlarged FFP reticle
Optic Magnification
The quantity of magnification a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Scopes
A single power rifle optic and scope comes with a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust given that it is set from the factory.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will list the zoom level in a configuration such as 2-10×32. These numbers mean the magnification of the scope could be set in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power adaptation is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Optics
Here are some suggested scope power levels and the distances where they may be efficiently used. High power glass will not be as useful as lower magnification glass because too much magnification can be a negative aspect depending on your shooting distance. The same goes for extended ranges where the shooter needs enough power to see where to properly aim the rifle.
Lens Coating for Rifle Scopes
All modern-day rifle optic and scope lenses are covered in special coatings. There are various types and qualities of lens coverings. Lens finishing is an important element of a rifle when thinking about high-end rifle optics and targeting equipment. The lenses are one of the most crucial parts of the glass considering they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens surface area and also improves anti glare capabilities from refracted sunlight and color perception.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coverings which use different procedures, elements, chemicals, and polarizations to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Rifle Optic Lens Single Finish Versus Multi-Coating
Various scope lenses can also have different coverings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It needs to have a coating applied to it so that the lens will be optimally functional in lots of types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing 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 specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
What to Know About Hydrophobic Finish
Water on an optic’s lens doesn’t support keeping a clear sight picture through an optic at all. Many top of the line and high-end scope producers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Glass on Long Guns
Installing approaches for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically come in quick release variations which use manual levers which enable rifle operators to quickly install and dismount the scopes.
Glass Mounts with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These forms of scope mounts use a pair of detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This form of scope mount is effective for rifle systems which need to have a resilient, unfailing mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized scope system on a long distance scouting or tournament long gun that will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to stop the hex screws from wiggling out after they are installed safely in position. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day on the range and your costly optic by causing fogging and generating residue within the scope’s tube. Most optics 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 underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are concerned about the scope still working if it goes over the side and you can still find the rifle.
Rifle Optic Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope’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 altered by temperature level alterations and pressure distinctions from the outside environment which might potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
