What You Need to Know About Scopes
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by making use of a set of lenses within the scope. The scope’s alignment can be adapted to take into account various ecological factors like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely 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 point of impact. Many modern-day rifle scopes and optics have around 11 parts which are located within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” equations for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who select a clearer optic sight picture with less area used up by the larger size FFP reticle
Zoom for Glass
The quantity of zoom a scope provides is identified by the diameter, 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 Scope Facts
A single power rifle scope comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change considering that it is a fixed power scope.
Info on Adjustable Power Lens Optics
Variable power rifle scopes use variable power levels. The power modification is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some recommended scope powers and the distances where they can be efficiently used. High power glass will not be as efficient as lower magnification rifle scope glass since too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to longer distances where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Coating for Optics
All contemporary rifle scope and optic lenses are coated. There are different types and qualities of glass coatings. When shopping for luxury rifle optics and scope systems, Lens finish can be a very important element of defining the capability of the rifle. The glass lenses are one of the most important parts of the optic since they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses shields the lens exterior and improves anti glare capabilities from refracted natural light and color recognition.
HD Versus ED Rifle Scope Lens Coatings
Some rifle glass makers also use “HD” or high-definition lens finishings that apply different procedures, elements, polarizations, and chemicals to draw out different color ranges and viewable target definition through the lens. This high-definition coating is often used with greater density glass which brings down light’s chance to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often obvious around items with well defined shapes as light hits the item from certain angles.
Single Glass Lens Finishing Versus Multi-Coating
Various optic lenses can also have various finishings used to them. All lenses generally have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope developer and how much you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This implies the lens has had numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a company is taking multiple actions to combat various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not always suggest the multi-coated lens will perform better than a single coated lens. Being “better” is dependent on the maker’s lens treatment solutions and the quality of materials used in constructing the rifle scope.
Info on Anti-water Finish
Water on a lens doesn’t improve maintaining a clear sight picture through a scope in any way. Lots of top of the line or premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Rifle Glass Installation Choices
Installing solutions for scopes can be found in a few choices. 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 can be found in quick release versions which use throw levers which enable rifle shooters to rapidly install and remove the optics.
Rifle Scope Mounting Solutions with Hex Key Rings
Normal, clamp style 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 often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope install is wonderful for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining precision. These types of mounts are useful and convenient for shooting platforms which are moved a lot, to remove the scope from the rifle for protection, or for sight systems which are chosen for use in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope Tubes
Another element of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less affected by temperature level alterations and pressure distinctions from the outdoor environment which might potentially allow 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 seek out.
