Info Rifle Scopes
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom using a series of lenses inside the scope. The scope’s alignment can be adapted for the consideration of varied environmental considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about eleven parts which are located within and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. See all eleven parts of an optic.
About Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has determines where the reticle or crosshair is located relative to the optic’s zoom. It literally suggests the reticle is located behind or in front of the magnifying lens of the scope. Looking for the most suitable form of rifle glass depends on what form of hunting or shooting you intend on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “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 circumstances where computations are very little
- Experienced shooters who understand their target “hold over” as well as “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This causes the reticle to stay at the same overall size relative to the level of zoom being used. The final result is that the reticle measurements alter based on the magnification applied to shoot over lengthier distances since the markings represent various increments which can vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of scopes are handy for:
- Long distance kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who like a clearer optic picture with less area used up by the larger size FFP reticle
Details on Glass Zoom
The quantity of zoom a scope offers 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.
Info on Fixed Single Power Lens Rifle Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is a fixed power optic.
Adjustable Power Lens Glass Details
Variable power rifle scopes can be modified between magnified levels. The power modification is handled using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the distances where they could be effectively used. Keep in mind that high magnification optics and scopes will not be as practical as lower powered scope and optics due to the fact that excessive magnification can be a detractor. The same concept applies to extended distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
About Lens Finishing
All modern rifle scope and optic lenses are covered in special coatings. There are various types and qualities of lens coatings. Lens finishing is an essential aspect of a rifle’s setup when thinking about high-end rifle optics and scope systems. The lenses are among the most vital components of the glass due to the fact that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and even improves anti glare capabilities from excess light and color profiles.
ED Versus HD Glass
Some scope companies even use “HD” or high-def glass coatings which employ different procedures, components, chemicals, and polarizations to enhance numerous color ranges and viewable target definition through the lens. This high-def finish is frequently used with greater density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often noticeable around objects with well defined shapes as light hits the object from specific angles.
What to Know About Single Finish Versus Multi-Coating
Different optic lenses can likewise have various finishes used to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope producer and how much money you paid for it. Both the make and cost are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Finish for Rifle Optics
Water on an optical lens does not assist with retaining a clear sight picture through a scope whatsoever. Many top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the exterior of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Installing Optics on Firearms
Mounting options for scopes are available in a few options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Optic Mounts with Hex Key Rings
Standard, clamp-on design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These types of scope mounts use double separate rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are manufactured for long distance accuracy shooting. This type of scope mount is effective for rifles which need a long lasting, rock solid mount which will not shift despite just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a dedicated optics setup on a reach out and touch someone hunting or tournament rifle that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screws from backing out after they are installed tightly in position. An example of these rings are the 30mm style made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a similar style mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle glass can destroy a day of shooting and your expensive optic by resulting in fogging and creating residue within the scope tube. A lot of scopes protect against moisture from going into the optical tube with a system of sealing O-rings which are water resistant. Usually, these scopes 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 prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are concerned about the optic still working if it falls overboard and you can still salvage the gun.
Rifle Glass Gas Purging
Another element of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the optic is less altered by temp shifts and pressure variations from the external environment which could potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
