Optic Details
Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous ecological factors like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have around 11 parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of rifle glass.
About Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the perfect type of rifle glass is based on what type of shooting you plan on doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) include the reticle before the magnification lens. This triggers the reticle to increase in size based on 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 example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minimal
- Experienced shooters who have an idea for their target “hold over” as well as “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane scopes (SFP) feature the reticle behind 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.
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and distances
- Shooters who like a clearer optic picture without space taken up by the enlarged FFP reticle
Magnification for Scopes
The amount of zoom a scope offers is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Info
A single power rifle scope and optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust because it is a set power scope.
Info About Variable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power change is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some advised scope power levels and the ranges where they could be effectively used. High power glass will not be as useful as lower magnification level scopes given that too much magnification can be a bad thing. The same idea relates to longer distances where the shooter needs to have adequate power to see where to properly aim the rifle.
Details on Rifle Scope Lens Covering
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass finishes. When looking at high end rifle targeting setups, Lens covering can be a crucial component of a rifle. The glass lenses are one of the most critical parts of the scope considering that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses protects the lens exterior and even improves anti glare capabilities from refracted daylight and color presence.
HD Versus ED Glass Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coverings which use different methods, chemicals, polarizations, and elements to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finish Versus Multi-Coating
Different optic lenses can also have different finishings applied to them. All lenses generally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It must have a covering placed on it so that it will be efficiently functional in lots of types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope developer and the amount you spent on it. Both are signs of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Scope Lens Finish
Water on an optic’s lens does not assist with keeping a clear sight picture through an optic in any way. Lots of top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Glass on Long Guns
Installing approaches for scopes can be found in a couple of options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also normally come in quick release variations which use manual levers which allow rifle operators to quickly mount and dismount the scopes.
Rifle Scope Mounting Solutions with Hex Key Rings
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use a pair of separate rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are designed for long distance accuracy shooting. This form of scope mount is good for rifle systems which require a durable, hard use mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a faithful optics setup on a long distance hunting or tournament firearm that will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to protect against the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, a number of scopes can also be switched on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are carried a lot, to take off the scope from the rifle for protection, or for sight systems which are used in between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
About Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can spoil a day on the range and your pricey optic by triggering fogging and making residue within the scope tube. A lot of scopes protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture avoidance for standard use rifles, unless you intend on taking your rifle on a boat and are worried about the scope still working if it goes over the side and you can still find the gun.
Rifle Optic Gas Purging
Another component of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less influenced by temperature level changes and pressure variations from the external environment which might possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
