About Glass
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through zoom by making use of a series of lenses within the scope. The scope’s positioning can be dialed in to account for various environmental factors like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle scopes and optics have about 11 parts which are found inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the best type of rifle glass depends on what type of shooting you plan to do.
Info About First Focal Plane Optics
First focal plane optics (FFP) come with the reticle before the zoom lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include 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 reticle measurement.
- Long distance types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who select a clearer optic picture with less space used up by the enlarged FFP reticle
Rifle Optic Zoom
The amount of zoom a scope supplies is figured out 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 Power Lens Rifle Optic Details
A single power rifle scope uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is a fixed power optic.
Adjustable Power Lens Glass Facts
Variable power rifle scopes have adjustable power. It will note the zoom level in a configuration such as 2-10×32. These numbers mean the zoom of the scope could be changed between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adaptation is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Range Correlation
Here are some advised scope powers and the ranges where they may be effectively used. Keep in mind that high power optics will not be as practical as lower powered optics and scopes due to the fact that increased magnification can be a bad thing. The same goes for extended distances where the shooter needs sufficient power to see precisely where to best aim the rifle.
Details on Lens Coatings
All state-of-the-art rifle optic and scope lenses are layered. Lens coating is an important aspect of a rifle when thinking about high end rifle optics and scope setups.
About Rifle Scope Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coatings which use various methods, polarizations, chemicals, and aspects to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Scope Lens Single Coating Versus Multi-Coating
Various optic lenses can even have different finishes applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. 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 numerous types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 on the scope company and how much you spent on it. The scope’s maker and cost are indications of the lens quality.
Some scope producers similarly 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 technology and the quality of products used in building the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on a lens does not improve retaining a clear sight picture through a scope in any way. Many top of the line or premium 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 provides protection for the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installing Options
Installing approaches for scopes come in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use throw levers which permit rifle operators to quickly install and dismount the scope.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use double independent rings to support the scope, and are normally made from 7075 T6 billet aluminum which are manufactured for long distance accuracy shooting. This type of scope mount is exceptional for rifles which need to have a long lasting, hard use mount which will not change no matter just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful scope system on a long distance scouting or interdiction rifle that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are mounted firmly in position. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
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. A wide range of scopes can also be switched out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These types of mounts are useful and beneficial for rifles which are shipped a lot, to take off the scope glass from the rifle for protection, or for optics which are utilized in between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
What to Know About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another element of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less altered by temperature alterations and pressure distinctions from the outside environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
