What You Need to Know About Scopes
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of numerous environmental considerations like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes have around eleven parts which are found inside and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. See all eleven parts of an optic.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the perfect type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are small
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who want a clearer optic sight picture without room taken up by the larger sized FFP reticle
Details on Scope Magnification
The quantity of magnification a scope provides is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Optics
A single power rifle optic comes with a magnification 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 type of optic can not adjust considering that it is set from the factory.
Info on Adjustable Power Lens Glass
Variable power rifle scopes use variable power levels. The power adjustment is handled by using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some suggested scope power levels and the distances where they may be effectively used. Consider that high magnification optics will not be as efficient as lower powered optics and scopes because too much zoom can be a detractor. The same concept relates to extended ranges where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.
Glass Lens Covering
All contemporary rifle scope and optic lenses are covered in special coatings. There are different types and qualities of lens coatings. Lens finish can be an important aspect of a rifle’s setup when looking at high-end rifle optics and targeting equipment. The glass lenses are one of the most critical parts of the optic since they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses offers protection to the lens surface and also helps with anti glare capabilities from excess daylight and color recognition.
ED Versus HD Rifle Scopes
Some glass suppliers also use “HD” or high-def lens finishes which employ various procedures, components, polarizations, and chemical applications to extract separate colors and viewable target definition through the lens. This high-definition covering is often used with more costly, high density lens glass which reduces light’s ability to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over items with hard edges and shapes as light hits the object from various angles.
Single Finishing Versus Multi-Coating
Different optic lenses can even have different coatings applied to them. All lenses typically have at least some type of treatment or coating applied to them before being used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It needs to have a finish placed on it so that it will be efficiently usable in lots of kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and how much you spent for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can establish that a maker is taking several steps to fight different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This additionally doesn’t necessarily indicate the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of products used in developing the rifle scope.
Anti-water Rifle Glass Lens Covering
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Optic Installation Options
Mounting options for scopes can be found in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Rifle Glass Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use a pair of individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are developed for far away precision shooting. This form of scope mount is exceptional for rifle systems which are in need of a long lasting, rock solid mount which will not change no matter how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a dedicated optics system on a reach out and touch someone scouting or sniper competition rifle which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to protect against the hex screws from backing out after they are mounted firmly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These types of mounts come in convenient for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for optics which are adopted between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can spoil a day of shooting and your highly-priced optic by causing fogging and making residue within the scope’s tube. Most optics protect against moisture from entering the scope tube with a system of sealing O-rings which are waterproof. Usually, these 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 avoidance for common use rifles, unless you plan on taking your rifle aboard watercrafts and are worried about the optic still performing if it is submerged in water and you can still retrieve the rifle.
Gas Purged Optic Tubes
Another component of preventing the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less altered by temp changes and pressure differences from the external environment which may potentially 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 seek out.
