Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be adjusted to account for numerous ecological aspects like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern rifle scopes have around 11 parts which are arranged inside and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other parts. See all eleven parts of optics.
About Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has determines where the reticle or crosshair is located relative to the scopes magnification. It literally means the reticle is behind or in front of the magnifying lens of the scope. Picking out the most suitable kind of rifle optic depends upon what type of shooting or hunting you intend on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who understand their target “hold over” plus “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Glass Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within shorter spaces and ranges
- Shooters who desire a clearer optic sight picture with less room used up by the enlarged FFP reticle
About Rifle Glass Magnification
The amount of zoom a scope supplies is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Optic Info
A single power rifle optic or scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power optic.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes use enhanced power. The power modification is performed using the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power Level and Range Correlation
Here are some advised scope power settings and the ranges where they may be successfully used. High power glass will not be as effective as lower magnification level rifle scope glass given that too much magnification can be a bad thing. The same relates to extended distances where the shooter needs to have enough power to see exactly where to properly aim the rifle.
About Lens Coverings
All modern-day rifle optic and scope lenses are layered. There are different types and qualities of lens coverings. Lens covering is an essential aspect of a rifle when thinking of high-end rifle optics and scope equipment. The lenses are among the most important pieces of the scope since 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 exterior and even assists with anti glare from excess sunshine and color visibility.
ED Versus HD Glass
Some rifle scope makers also use “HD” or high-definition lense finishings which apply various procedures, polarizations, elements, and chemicals to enhance numerous colors and viewable target definition through lenses. This HD finishing is normally used with increased density glass which decreases light’s ability to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over items with well defined shapes as light hits the item from various angles.
Single Scope Lens Finishing Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope manufacturer and how much money you paid for it. The scope’s maker and cost are indications of the lens quality.
Some scope makers also make it a point to define 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.
Anti-water Finishing for Optics
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water finish.
Alternatives for Installing Rifle Glass on Long Guns
Installing approaches for scopes come in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release versions which use throw levers which enable rifle operators to rapidly install and dismount the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This kind of scope mount is great for rifle systems which are in need of a resilient, rock solid mount which will not change no matter how much the scope is moved about or abuse the rifle takes. These are the style of mounts you want for a faithful scope system on a long distance scouting or competition long gun that will almost never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from backing out after they are mounted tightly in place. An example of these rings are the 30mm style from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms 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 or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle glass can mess up a day of shooting and your costly optic by inducing fogging and generating residue within the scope’s tube. Many scopes protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Normally, these water-resistant optics 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 wetness prevention for common use rifles, unless you plan on taking your rifle aboard a watercraft and are concerned about the scope still functioning if it goes over the side and you can still retrieve the gun.
Gas Purged Rifle Optic Tubes
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less influenced by temperature changes and pressure variations from the outside environment which might possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
