Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target over a range. They do this through magnification using a series of lenses within the scope. The scope’s positioning can be dialed in for consideration of numerous environmental aspects like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle scopes and optics have about eleven parts which are located internally and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification dials, focus rings, and other parts. Learn about the eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has identifies where the reticle or crosshair is located in regard to the optic’s magnification. It simply means the reticle is behind or before the magnification lens of the optic. Considering the very best type of rifle glass is based on what variety of shooting you anticipate doing.
First Focal Plane Scope Facts
First focal plane glass (FFP) include the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are low
- Experienced shooters who recognize their target “hold over” as well as “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within much shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture with less space taken up by the bigger FFP reticle
The amount of magnification a scope offers is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass
A single power rifle optic will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change since it is fixed.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power modification is handled by using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power Level and Range Correlation
Here are some suggested scope power settings and the ranges where they may be successfully used. High power optics will not be as beneficial as lower powered optics because too much magnification can be a bad thing. The same relates to extended distances where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Lens Covering for Rifle Scopes
All present day rifle scope lenses are layered. Lens finish can be an important element of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some glass producers additionally use “HD” or high-def glass coatings which apply various processes, chemical applications, polarizations, and aspects to extract different colors and viewable definition through lenses. This high-definition finishing is typically used with increased density glass which brings down light’s ability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with hard shapes as light hits the object from particular angles.
Single Finishing Versus Multi-Coating for Glass
Different optic lenses can likewise have various finishings used to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard 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 coated lens depends on the scope producer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Scope Lens Hydrophobic Finish
Water on a scope’s lens doesn’t assist with keeping a clear sight picture through an optic at all. Numerous top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the exterior of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Rifle Glass Installation Options
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on the tops of rifles. These types of scope mounts use a pair of separate rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This type of scope mount is good for rifle systems which need a resilient, hard use mount which will not move despite just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you want for a specialized scope system on a far away hunting or hard target interdiction rifle which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to keep the hex screws from backing out after they are mounted securely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can wreck a day on the range and your highly-priced optic by causing fogging and developing residue within the scope’s tube. Most optics prevent moisture from getting in the optical tube with a series of sealing O-rings which are water resistant. Typically, these water resistant 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 more than enough moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are concerned about the scope still working if it falls overboard and you can still find the firearm.
What to Know About Rifle Optic Tube Gas Purging
Another part of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the glass is less altered by condition changes and pressure variations from the outside environment which may possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
