What You Need to Know About Scopes
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through zoom by using a series of lenses inside the scope. The scope’s positioning can be dialed in to account for many natural considerations like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have around eleven parts which are found within and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other components. See all eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle glass is based on what type of shooting you plan to do.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have additional 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 space used up by the larger sized FFP reticle
Rifle Optic Zoom
The quantity of zoom a scope provides is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Optic Info
A single power rifle scope will have a magnification number designator like 4×32. This means 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 since it is a fixed power scope.
Variable Power Lens Optic Details
Variable power rifle scopes can be adjusted between magnification increments. It will list the magnification amount in a format like 2-10×32. These numbers mean the magnification of the scope could be adjusted in between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power modification is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the distances where they may be efficiently used. High power scopes will not be as useful as lower magnification level rifle scope glass since too much magnification can be a bad thing. The same applies to extended distances where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Finishing for Rifle Glass
All modern rifle optic and scope lenses are coated. There are various types and qualities of lens finishings. When thinking about luxury rifle optics and scope units, Lens finishing can be a very important aspect of defining the capability of the rifle. The lenses are among the most critical parts of the optic given that they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens surface as well as assists with anti glare capabilities from excess daylight and color recognition.
ED Versus HD Optics
Some scope manufacturers likewise use “HD” or high-definition lens finishes which use various procedures, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Rifle Glass Lens Covering Versus Multi-Coating
Different optic lenses can also have various finishings used to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Rifle Scope Lens Coating
Water on a scope lens doesn’t help with keeping a clear sight picture through a scope in any way. Many top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Optic Installation Options
Mounting options for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use toss levers which allow rifle operators to quickly mount and remove the glass.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope install is fine for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Several 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 protection, or for optics which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day on the range and your pricey optic by resulting in fogging and developing residue within the scope tube. Many optics prevent moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be submerged within 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 anticipate taking your rifle boating and are worried about the optic still performing if it goes over the side and you can still salvage the gun.
Optic Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the glass is less influenced by condition alterations and pressure distinctions from the outdoor environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
