What You Need to Know About Scopes
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by employing a series of lenses inside the scope. The scope’s positioning can be adapted to take into account different natural things like wind and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes and optics have around eleven parts which are located internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other components. See all eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has identifies where the reticle or crosshair is located in regard to the scopes magnifying adjustments. It simply means the reticle is behind or ahead of the magnifying lens of the scope. Picking the best form of rifle optic is based on what type of shooting or hunting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who understand their target “hold over” plus “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the exact same dimensions in relation to the amount of magnification being used. The effect is that the reticle measurements evolve based on the zoom chosen to shoot over longer ranges considering the markings represent different increments which differ with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular types of glass work for:
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who would like a clearer optic picture without space used up by the larger sized FFP reticle
Zoom for Rifle Optics
The quantity of magnification a scope supplies 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 Scopes
A single power rifle optic will have a zoom 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 kind of scope can not adjust considering that it is a set power scope.
Variable Power Lens Optic Facts
Variable power rifle scopes use enhanced power. 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 ranges where they may be efficiently used. High power rifle scope glass will not be as beneficial as lower magnification level optics because too much zoom can be a negative aspect depending on your shooting distance. The same relates to longer ranges where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
About Glass Lens Finish
All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of glass coverings. Lens coating is an essential element of a rifle when contemplating high-end rifle optics and targeting units. The lenses are among the most significant parts of the glass given that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses protects the lens exterior and also improves anti glare capabilities from excess light and color presence.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some rifle glass suppliers additionally use “HD” or high-def lense coatings that apply different procedures, chemicals, elements, and polarizations to extract numerous colors and viewable target definition through lenses. This high-def finishing is often used with higher density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope producers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable around things with defined outlines as light hits the item from specific angles.
Rifle Optic Lens Single Covering Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses normally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope manufacturer and how much money you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has several treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a manufacturer is taking several steps to combat various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens will perform better than a single layered lens. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle optic.
Hydrophobic Lens Coverings
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water covering.
Rifle Glass Installation Options
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release variations which use toss levers which permit rifle shooters to quickly mount and remove the glass.
Hex Key Glass Rings
Basic, clamp-on type mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This type of scope mount is good for rifles which require a resilient, unfailing mount which will not move despite how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated scope setup on a reach out and touch someone scouting or sniper competition firearm which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screw threads from backing out after they are mounted tightly in position. An example of these rings are the 30mm type from the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass 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. Multiple scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifles which are transported a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can ruin a day on the range and your highly-priced optic by triggering fogging and creating residue within the scope’s tube. Most scopes protect against humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for conventional use rifles, unless you anticipate taking your rifle aboard a watercraft and are concerned about the optic still functioning if it falls overboard and you can still rescue the rifle.
Gas Purged Rifle Optic Tubes
Another part of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the scope is less affected by temperature changes and pressure variations from the outside environment which could possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
