What You Need to Know About Scopes
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom using a set of lenses within the scope. The scope’s alignment can be dialed in to account for various environmental considerations like wind speed and elevation 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 viewing via the scope as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes and optics have about eleven parts which are arranged within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of glass.
About Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle glass is based around what type of shooting you plan to do.
Info on First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. This induces the reticle to stay at the very same scale in relation to the quantity of magnification being used. The effect is that the reticle measurements adapt based upon the zoom used to shoot over greater distances considering the markings present distinct increments which fluctuate with the magnification level. 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 measurement. These particular varieties of glass work for:
- Long distance styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who want a clearer optic picture with less space taken up by the larger size FFP reticle
Scope Zoom
The measure of scope magnification you need on your scope depends upon the form of shooting you wish to do. Nearly every style of rifle glass delivers some degree of magnification. The level of zoom a scope provides is determined by the dimension, thickness, and curves of the lenses within the rifle scope. The magnification level of the scope is the “power” of the opic. This signifies what the shooter is aiming at through the scope is magnified times the power element of what can generally be seen by human eyes.
Fixed Single Power Lens Optic Facts
A single power rifle scope and optic comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power scope.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some suggested scope power levels and the distances where they may be effectively used. High power scopes will not be as beneficial as lower magnification glass due to the fact that too much zoom can be a bad thing. The same goes for longer ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Coating for Rifle Glass
All present day rifle optic and scope lenses are coated. Lens covering can be a vital element of a rifle when looking at high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some glass companies will also use “HD” or high-definition glass finishings which use different procedures, chemicals, components, and polarizations to extract a wide range of colors and viewable target visibility through the lens. This high-def coating is commonly used with more costly high density glass which decreases light’s capability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be visible over items with hard edges and shapes as light hits the item from specific angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can even have different finishings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in numerous types of environments, degrees of light (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve 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 layered lens depends on the scope company and how much you spent on it. Both are signs of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can indicate that a producer is taking multiple steps to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This additionally does not always mean the multi-coated lens is much better than a single covered lens. Being “much better” depends on the producer’s lens treatment techniques and the quality of components used in constructing the rifle scope.
Scope Lens Anti-water Finishing
Water on a scope’s lens does not assist with maintaining a clear sight picture through an optic whatsoever. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Rifle Scope Installing Options
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use toss levers which allow rifle operators to rapidly install and remove the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
Basic, clamp-on type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use double individual rings to support the optic, and are made from 7075 T6 billet aluminum which are made for far away precision shooting. This form of scope mount is ideal for rifle systems which require a resilient, hard use 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 really want to have for a specialized scope setup on a long distance scouting or tournament long gun which will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to prevent the hex screw threads from wiggling out after they are mounted safely in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
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. Several scopes can even be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles.
Info Around Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can spoil a day on the range and your expensive optic by causing fogging and making residue inside of the scope’s tube. The majority of optics prevent moisture from entering the optical tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are concerned about the optic still working if it falls overboard and you can still find the firearm.
Gas Purged Rifle Scope Tubes
Another component of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less affected by temp alterations and pressure distinctions from the outdoor environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
