Rifle Optic Facts
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target over a range. They do this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adjusted for the consideration of numerous environmental considerations like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes and optics have about eleven parts which are arranged internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. See all eleven parts of a rifle optical system.
The Varieties 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 determines where the reticle or crosshair is located in connection with the optic’s zoom. It simply suggests the reticle is located behind or in front of the magnification lens of the scope. Selecting the very best form of rifle glass is based on what variety of shooting or hunting you anticipate undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” ratios for their firearms
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots happen within shorter spaces and ranges
- Shooters who prefer a clearer optic picture with less room used up by the enlarged FFP reticle
Scope Zoom
The quantity of zoom a scope provides is figured out 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.
Single Power Lens Glass
A single power rifle optic or scope will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change since it is a fixed power scope.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power modification is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some advised scope power settings and the distances where they can be successfully used. Highly magnified scopes will not be as useful as lower powered glass considering too much magnification can be a negative aspect depending on your shooting distance. The very same idea applies to extended ranges where the shooter needs to have enough power to see precisely where to best aim the rifle.
Info on Rifle Optic Lens Coating
All contemporary rifle scope and optic lenses are covered. Lens coating is an important element of a shooting platform when considering high end rifle optics and scope equipment.
HD Versus ED Lenses
Some rifle scope companies will also use “HD” or high-definition lense finishings that employ various processes, chemicals, polarizations, and components to enhance different color ranges and viewable target visibility through the lens. This high-def finishing is normally used with higher density glass which decreases light’s ability to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over objects with hard edges and shapes as light hits the object from particular angles.
Info on Single Finishing Versus Multi-Coating
Various scope lenses can even have various finishes applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. 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 needs to have a coating applied to it so that it will be efficiently usable in numerous kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives several treatments, it can indicate that a company is taking several steps to combat various natural factors like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment technology and the quality of materials used in creating the rifle optic.
Hydrophobic Lens Finishing
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Options for Mounting Rifle Scopes on Firearms
Installing options for scopes come in a couple of choices. 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 can be found in quick release versions which use throw levers which enable rifle shooters to rapidly mount and remove the scopes.
Scope Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope mount is wonderful for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped 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 fasten firmly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are transferred a lot, to take off the glass from the rifle for protection, or for scopes which are used in between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by resulting in fogging and generating residue within the scope tube. Many scopes prevent moisture from entering the optical tube with a system of sealing O-rings which are water resistant. Normally, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are concerned about the optic still functioning if it goes over the side and you can still find the gun.
Details on Scope Tube Gas Purging
Another part of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less impacted by temperature level changes and pressure variations from the outdoor environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
