Information Scopes
Rifle scopes enable you to specifically align a rifle at various 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 positioning can be adjusted for the consideration of various natural elements like wind and elevation 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 scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have about 11 parts which are found internally and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the finest type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their aim point “hold over” and also “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who desire a clearer optic picture without space used up by the enlarged FFP reticle
Rifle Optic Magnification
The measure of scope zoom you need on your scope depends upon the type of shooting you want to do. Virtually every type of rifle optic delivers some degree of magnification. The level of zoom a scope supplies is established by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is magnified times the power factor of what can normally be seen by human eyes.
Single Power Lens Scope Facts
A single power rifle optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is a fixed power optic.
Variable Power Lens Rifle Optic Info
Variable power rifle scopes use variable power levels. The power change is handled by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some advised scope power levels and the ranges where they could be effectively used. Consider that high magnification glass will not be as effective as lower powered optics and scopes since increased magnification can be a detractor. The very same idea goes for extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle at the target.
Rifle Optic Lens Coating
All present day rifle scope lenses are covered. Lens covering can be an important aspect of a shooting system when purchasing high end rifle optics and scope setups.
About Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens finishings which use various techniques, polarizations, components, and chemicals to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finish Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses usually have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a covering placed on it so that it will be efficiently functional in many kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you spent on it. Both are indicators of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Glass Lens Anti-water Finishing
Water on a scope’s lens doesn’t help with preserving a clear sight picture through a scope in any way. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Scope Installation Options
Installing solutions for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use manual levers which allow rifle shooters to quickly mount and remove the optics.
Hex Key Optic Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design 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 distance precision shooting. This type of scope mount is perfect for rifles which require a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a similar style mount. These types of mounts are handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day of shooting and your pricey optic by inducing fogging and generating residue inside of the scope’s tube. The majority of scopes protect against wetness from entering the scope tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are worried about the optic still functioning if it goes over the side and you can still retrieve the rifle.
Info Around Optic Tube Gas Purging
Another part of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the scope is less affected by temperature level alterations and pressure distinctions from the outside environment which could possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
