About Scopes
Rifle scopes permit you to exactly align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adapted to take into account separate environmental considerations like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have about 11 parts which are found inside and outside of the optic. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other elements. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in relation to the optic’s magnification. It simply suggests the reticle is situated behind or before the magnifying lens of the scope. Picking out the most ideal kind of rifle glass depends on what sort of shooting or hunting you anticipate undertaking.
Info About First Focal Plane Glass
First focal plane optics (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who know their target “hold over” and “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick 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 estimations
- Shooting where most of the shots occur within much shorter distances and ranges
- Shooters who like a clearer optic picture without room taken up by the enlarged FFP reticle
Magnification for Rifle Optics
The amount of magnification a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Fixed Single Power Lens Scopes
A single power rifle optic and scope uses a magnification number designator like 4×32. This suggests 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 a fixed power optic.
Info on Variable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Glass
Here are some suggested scope powers and the ranges where they could be efficiently used. Always remember that high magnification optics will not be as practical as lower powered scope and optics since increased zoom can be a detractor. The same concept goes for longer ranges where the shooter needs enough power to see where to properly aim the rifle.
Details on Lens Coatings
All contemporary rifle optic and scope lenses are layered. There are different types and qualities of glass lens coatings. Lens finish can be an important element of a rifle’s setup when considering high end rifle optics and scope units. The glass lenses are among the most essential parts of the optic because 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 surface as well as assists with anti glare capabilities from excess light and color exposure.
ED Versus HD Scopes
Some scope producers also use “HD” or high-definition lens finishings which use different procedures, aspects, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Glass Lens Covering Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses typically have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard 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 layered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets several treatments, it can prove that a maker is taking multiple actions to combat various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally doesn’t necessarily imply the multi-coated lens is better than a single covered lens. Being “much better” depends upon the producer’s lens treatment solutions and the quality of materials used in building the rifle glass.
Optic Lens Anti-water Coating
Water on an optical lens doesn’t support retaining a clear sight picture through an optic at all. Numerous 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 fine example of this kind of treatment. It treats the surface area of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Long Guns
Mounting approaches for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use manual levers which enable rifle shooters to rapidly mount and dismount the glass.
Hex Key Rifle Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope install is excellent for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles.
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day on the range and your highly-priced optic by inducing fogging and developing residue within the scope tube. The majority of scopes protect against moisture from entering the scope tube with a series of sealing O-rings which are water resistant. Typically, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough humidity avoidance for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are concerned about the scope still working if it is submerged in water and you can still recover the rifle.
Gas Purged Optic Tubes
Another element 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 taken up by the gas, the glass is less influenced by climate alterations and pressure distinctions from the outside environment which might potentially enable water vapor to seep 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.
