All About Scopes
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for different environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about eleven parts which are located inside and outside 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. Learn about the eleven parts of rifle glass.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has establishes where the reticle or crosshair lies in regard to the scopes magnification. It literally implies the reticle is located behind or in front of the magnifying lens of the optic. Looking for the most desired kind of rifle glass depends upon what variety of hunting or shooting you plan on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at one hundred yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who know their aim point “hold over” and “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. This causes the reticle to stay at the very same scale relative to the volume of zoom being used. The result is that the reticle measurements adapt based upon the zoom applied to shoot over greater ranges given that the markings represent different increments which fluctuate with the zoom. 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. These sorts of optics work for:
- Long distance kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who select a clearer optic sight picture without space taken up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Zoom
The quantity of magnification a scope provides is identified 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.
Fixed Power Lens Optics
A single power rifle optic will have 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 magnification of this type of scope can not adjust because it is fixed.
About Variable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified levels. The power change is handled by using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Glass
Here are some recommended scope powers and the ranges where they can be effectively used. Bear in mind that higher power scopes and optics will not be as practical as lower powered scope and optics because too much zoom can be a detractor. The very same idea relates to longer distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Rifle Scope Lens Covering
All top of the line rifle optic lenses are coated. Lens finish is a crucial aspect of a shooting system when thinking about high end rifle optics and scope equipment.
ED Versus HD Scopes
Some scope makers also use “HD” or high-definition lens coatings which use various procedures, chemicals, polarizations, and aspects to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope developer and how much you paid for it. Both are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Finishing for Rifle Glass
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Installing Optics on Long Guns
Installing approaches for scopes come in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use toss levers which permit rifle operators to rapidly mount and dismount the glass.
Hex Key Glass Rings
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use double separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are developed for far away precision shooting. This type of scope mount is very good for rifles which need a resilient, unfailing mount which will not move no matter how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a specialized scope setup on a reach out and touch someone scouting or sniper competition long gun that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screw threads from wiggling out after they are installed safely in place. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles or are situationally focused.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by inducing fogging and creating residue inside of the scope’s tube. The majority of optics prevent humidity from getting in the scope tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness avoidance for standard use rifles, unless you intend on taking your rifle on boats and are concerned about the scope still functioning if it falls overboard and you can still salvage the firearm.
Gas Purged Glass Tubes
Another component of avoiding the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less affected by temperature shifts and pressure differences from the external environment which may potentially enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
