Optic Details
Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of different natural elements like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters 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 optics have around 11 parts which are located within and externally on the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. Learn about the eleven parts of glass.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the finest type of rifle optic depends 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 helpful for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This causes the reticle to remain at the same size in relation to the quantity of magnification being used. The end result is that the reticle measurements adapt based upon the magnification applied to shoot over lengthier ranges because the markings present different increments which vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular styles of glass work for:
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who like a clearer optic picture without area taken up by the larger sized FFP reticle
Scope Zoom
The extent of scope zoom you require is based on the type of shooting you desire to do. Virtually every kind of rifle optic supplies some amount of zoom. The volume of zoom a scope supplies is established by the dimension, thickness, and curves of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the opic. This denotes what the shooter is aiming at through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Scope Info
A single power rifle optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change considering that it is fixed.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification increments. It will list the magnification level in a format such as 2-10×32. These numbers mean the magnification of the scope could be set in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power manipulation is achieved by working with the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Optic Power Level and Ranges
Here are some advised scope power levels and the ranges where they could be successfully used. Bear in mind that higher power glass will not be as efficient as lower powered optics and scopes because excessive zoom can be a negative thing in certain situations. The exact same concept applies to longer distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Lens Finishing for Rifle Glass
All contemporary rifle optic and scope lenses are layered. There are different types and qualities of lens finishings. When considering luxury rifle targeting setups, Lens finishing can be an essential component of defining the capability of the rifle. The lenses are among the most essential pieces of the optic considering they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface and assists with anti glare from excess sunrays and color presence.
ED Versus HD Rifle Glass
Some scope brands likewise use “HD” or high-definition lens coatings which use various procedures, aspects, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Optic Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses usually have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope developer and how much you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Finishing for Scopes
Water on a scope lens doesn’t help with maintaining a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface area of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Optic Mounting Choices
Installing approaches for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally come in quick release versions which use toss levers which enable rifle shooters to quickly mount and dismount the scopes.
Hex Key Rifle Scope Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is fine for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can spoil a day on the range and your costly optic by causing fogging and developing residue inside of the scope’s tube. Many scopes protect against moisture from going into the optical tube with a system of sealing O-rings which are waterproof. 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 plenty of moisture content avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are concerned about the scope still performing if it falls overboard and you can still salvage the gun.
Rifle Optic Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less altered by condition shifts and pressure variations from the outdoor environment which may possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
