What You Need to Know About Rifle Scopes
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be adapted for consideration of different environmental things 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 seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes and optics have about 11 parts which are found within and outside of the optic. These optic pieces include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other components. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has identifies where the reticle or crosshair lies in regard to the optic’s magnification. It actually means the reticle is behind or in front of the magnifying lens of the scope. Deciding upon the most effective type of rifle glass is based on what variety of hunting or shooting you plan on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the extent 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 range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who recognize their target “hold over” as well as “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who select a clearer optic picture with less area used up by the enlarged FFP reticle
Glass Zoom
The measure of scope magnification you need on your scope depends upon the sort of shooting you desire to do. Just about every style of rifle scope provides some degree of magnification. The quantity of zoom a scope offers is determined by the size, density, and curves of the lens glass within the rifle optic. The magnifying level of the optic is the “power” of the opic. This means what the shooter is observing through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle scope and optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust given that it is a set power scope.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes use enhanced power. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some recommended scope powers and the ranges where they could be effectively used. Keep in mind that high power optics and scopes will not be as effective as lower powered glass due to the fact that excessive magnification can be a detractor. The same goes for extended distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Lens Covering for Glass
All modern rifle scope and optic lenses are coated. Lens finish can be an essential aspect of a shooting system when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle glass producers additionally use “HD” or high-def lens finishings that use different processes, polarizations, chemicals, and elements to enhance different colors and viewable target definition through lenses. This high-def coating is frequently used with greater density lens glass which brings down light’s capability to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often visible over things with hard edges and outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating for Glass
Various optic lenses can also have different coverings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope company and just how much you spent for it. Both are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has multiple treatments applied to the surfaces. If a lens gets numerous treatments, it can prove that a manufacturer is taking numerous steps to combat different environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also does not always indicate the multi-coated lens will perform better than a single covered lens. Being “better” depends upon the producer’s lens treatment solutions and the quality of products used in developing the rifle optic.
Anti-water Finish for Optics
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finish which is water repellent.
Alternatives for Mounting Glass on Firearms
Mounting options for scopes can be found in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use throw levers which permit rifle operators to rapidly mount and remove the glass.
Hex Key Optic Ring Mounting Solutions
Standard, clamp style 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is great for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. Several scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These types of mounts come in convenient for shooting platforms which are hauled around a lot, to take off the optic from the rifle for protection, or for optics which are employed between multiple rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your highly-priced optic by resulting in fogging and making residue within the scope tube. The majority of optics protect against humidity from going into the scope tube with a system of sealing O-rings which are water resistant. Typically, these water resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity prevention for conventional use rifles, unless you plan on taking your rifle sailing and are worried about the scope still performing if it goes overboard and you can still find the gun.
Gas Purged Rifle Glass Tubes
Another part of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less influenced by temp shifts and pressure distinctions from the outside environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
