Scope Facts
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through zoom by using a series of lenses within the scope. The scope’s alignment can be adapted to account for many environmental aspects like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have around eleven parts which are arranged internally and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has determines where the reticle or crosshair is located in regard to the scopes zoom. It literally means the reticle is located behind or before the magnification lens of the scope. Deciding on the most effective type of rifle scope is based on what form of shooting or hunting you intend on undertaking.
First Focal Plane Optic Info
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. This induces the reticle to remain at the exact same size in connection with the quantity of zoom being used. The end result is that the reticle measurements evolve based on the magnification used to shoot over lengthier distances considering that the reticle measurements present different increments which differ with the zoom. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular styles of scopes are convenient for:
- Far away forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture without space taken up by the larger sized FFP reticle
Rifle Glass Magnification
The extent of scope magnification you need on your scope depends on the type of shooting you wish to do. Virtually every kind of rifle glass offers some level of zoom. The level of magnification a scope delivers is identified by the dimension, thickness, and curves of the lens glass inside of the rifle scope. The magnification level of the optic is the “power” of the scope. This signifies what the shooter is observing through the scope is magnified times the power aspect of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power optic.
Info About Adjustable Power Lens Scopes
Variable power rifle scopes can be changed between magnification power levels. It will list the zoom degree in a configuration like 2-10×32. These numbers imply the zoom of the scope could be adjusted in between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adaptation is accomplished utilizing the power ring component of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Scopes
Here are some recommended scope powers and the distances where they can be effectively used. Always remember that higher power scopes and optics will not be as efficient as lower powered optics since increased zoom can be a bad thing. The exact same concept goes for extended distances where the shooter needs enough power to see where to best aim the rifle at the target.
Info on Scope Lens Finishes
All modern-day rifle optic lenses are covered in special coatings. There are various types and qualities of glass finishes. When researching high end rifle optical setups, Lens finish can be a vital element of a rifle. The glass lenses are among the most crucial pieces of the glass given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface and helps with anti glare capabilities from refracted sunrays and color recognition.
HD Versus ED Rifle Scope Lens Coatings
Some scope producers also use “HD” or high-definition lens coverings which use various techniques, aspects, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Details on Single Finish Versus Multi-Coating
Different scope lenses can even have different coatings applied to them. All lenses usually have at least some kind of treatment or covering applied to them before they are 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 carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope developer and the amount you spent for it. The scope’s maker and cost are signs of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Rifle Glass Installing Options
Installing solutions for scopes are available in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which allow rifle operators to quickly install and dismount the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This kind of scope mount is great for rifles which require a durable, rock solid mount which will not shift despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you want for a devoted optics system on a reach out and touch someone scouting or tournament rifle that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screw threads from wiggling out after they are installed securely in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever 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. Numerous scopes can also be switched out if they all use a similar design mount. These types of mounts are handy 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 numerous rifles.
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle scope can wreck a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope’s tube. Most optics protect against wetness from entering the scope tube with a system of sealing O-rings which are waterproof. Typically, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture prevention for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are worried about the scope still functioning if it goes overboard and you can still recover the gun.
Details on Scope Tube Gas Purging
Another part of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the optic is less influenced by condition shifts and pressure variations from the outdoor environment which may possibly permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
