Scope Facts
Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a set of lenses within the scope. The scope’s alignment can be adjusted to take into account numerous ecological things like wind and elevation increases 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 seeing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have about 11 parts which are located internally and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other components. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Optics
First focal plane glass (FFP) feature the reticle ahead of the magnifying lens. This causes the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their firearms
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same overall size in connection with the volume of zoom being used. The result is that the reticle measurements adjust based on the zoom used to shoot over longer ranges considering the markings represent different increments which can vary with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular types of scopes work for:
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who desire a clearer optic picture without room taken up by the bigger FFP reticle
Ins and Outs of Glass Magnification
The extent of scope magnification you require is based on the style of shooting you would like to do. Practically every style of rifle scope gives some degree of magnification. The level of magnification a scope delivers is determined by the dimension, density, and curves of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope. This implies what the shooter is looking at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Fixed Power Lens Rifle Scopes
A single power rifle scope or optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change since it is a fixed power scope.
Adjustable Power Lens Scope Details
Variable power rifle scopes use enhanced power. The power change is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power and Ranges
Here are some recommended scope powers and the distances where they can be successfully used. High power rifle scope glass will not be as effective as lower powered scopes since too much zoom can be a negative aspect depending on your shooting distance. The same idea relates to longer ranges where the shooter needs to have adequate power to see precisely where to best aim the rifle at the target.
Rifle Optic Lens Finish
All modern-day rifle optic lenses are covered in special coatings. There are different types and qualities of glass finishings. When looking at luxury rifle optics and scope setups, Lens finishing can be an essential element of a rifle. The lenses are one of the most significant parts of the scope because they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface and even helps with anti glare capabilities from excess sunrays and color recognition.
About Optic Lens Coatings – HD Versus ED
Some rifle glass companies also use “HD” or high-definition glass finishes that use various processes, polarizations, chemicals, and aspects to extract a wide range of colors and viewable definition through the lens. This high-def covering is typically used with more costly, high density glass which reduces light’s opportunity to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible over objects with hard shapes as light hits the object from particular angles.
Single Finish Versus Multi-Coating for Optics
Different scope lenses can also have different finishes applied to them. All lenses typically have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing 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 developer and just how much you spent on it. Both are indications of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” coated. This means the lens has had several treatments applied to them. If a lens gets multiple treatments, it can show that a producer is taking numerous actions to combat different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens is better than a single layered lens. Being “much better” depends upon the producer’s lens treatment techniques and the quality of products used in developing the rifle scope.
Hydrophobic Glass Lens Finishing
Water on an optical lens does not support keeping a clear sight picture through an optic at all. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Optic Installing Options
Installing approaches for scopes are available in a few options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use throw levers which permit rifle operators to rapidly mount and dismount the scope.
Hex Key Rifle Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope mount is excellent for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Glass Tubes
Another part of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less affected by condition changes and pressure distinctions from the external environment which might potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
