What You Need to Know About Scopes
Rifle scopes permit you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through magnification using a series of lenses within the scope. The scope’s positioning can be adjusted to account for many environmental factors like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have around eleven parts which are arranged inside and on the exterior of the optic. These parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has decides where the reticle or crosshair lies relative to the scopes zoom. It literally means the reticle is situated behind or before the magnifying lens of the scope. Considering the best sort of rifle glass is based upon what sort of shooting you anticipate undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who know their target “hold over” plus “lead” relationships for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle to the rear of the magnifying lens. This induces the reticle to stay at the same overall size relative to the quantity of zoom being used. The end result is that the reticle measurements change based upon the magnification chosen to shoot over lengthier distances considering the reticle measurements present various increments which change with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular kinds of scopes are handy for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within much shorter proximities and ranges
- Shooters who want a clearer optic picture without room used up by the larger sized FFP reticle
Details on Optic Zoom
The amount of magnification a scope provides is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Single Power Lens Rifle Scopes
A single power rifle scope comes with a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power scope.
Adjustable Power Lens Optic Details
Variable power rifle scopes have adjustable power. It will list the magnification level in a format like 2-10×32. These numbers suggest the zoom of the scope can be set in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some recommended scope power settings and the ranges where they could be effectively used. Consider that higher power optics and scopes will not be as efficient as lower powered optics since excessive magnification can be a bad thing. The same concept relates to longer distances where the shooter needs sufficient power to see precisely where to best aim the rifle at the target.
Lens Covering for Glass
All top of the line rifle scope and optic lenses are coated. Lens finishing can be an essential element of a rifle when looking into high end rifle optics and scope setups.
HD Versus ED Rifle Scope Lens Coatings
Some glass makers also use “HD” or high-definition lense finishes which take advantage of various procedures, polarizations, aspects, and chemicals to draw out a wide range of color ranges and viewable target definition through lenses. This HD finishing is commonly used with more costly high density lens glass which reduces light’s potential to refract through the lens glass. Some scope brands use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over objects with hard outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It must have a coating applied to it so that it will be efficiently usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope designer and how much money you paid for it. Both the make and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can indicate that a manufacturer is taking numerous actions to combat different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not always suggest the multi-coated lens will perform better than a single covered lens. Being “better” is dependent on the manufacturer’s lens treatment technology and the quality of materials used in creating the rifle scope.
Anti-water Coating for Rifle Scopes
Water on a scope’s lens doesn’t support keeping a clear sight picture through a scope in any way. Many top of the line and high-end optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface 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.
Options for Installing Rifle Optics on Firearms
Installing options for scopes come 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 types of mounts also normally come in quick release variations which use toss levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Optic Rings
Standard, 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Numerous scopes can even be switched out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles.
Info on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your expensive optic by inducing fogging and creating residue inside of the scope’s tube. A lot of scopes prevent wetness from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the scope still working if it goes over the side and you can still recover the gun.
Details on Rifle Optic Tube Gas Purging
Another component of preventing the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less affected by temperature shifts and pressure distinctions from the outside environment which could potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
