Optic Details
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted to account for various natural things like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle optics have around eleven parts which are located internally and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. 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” type of optics. Considering the perfect type of rifle optic is based on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who recognize their target “hold over” and “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This induces the reticle to remain at the same dimensions in connection with the amount of zoom being used. The effect is that the reticle dimensions change based on the zoom employed to shoot over greater distances considering that the reticle markings present different increments which can vary with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These particular types of optics work for:
- Far away types of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who like a clearer optic picture with less area used up by the larger sized FFP reticle
Ins and Outs of Rifle Glass Magnification
The quantity of scope magnification you need on your scope is based on the form of shooting you like to do. Almost every style of rifle scope delivers some amount of magnification. The amount of zoom a scope delivers is identified by the diameter, density, and curvatures of the lens glass within the rifle optic. The zoom of the scope is the “power” of the opic. This denotes what the shooter is aiming at through the scope is magnified times the power factor of what can typically be seen by human eyes.
About Single Power Lens Glass
A single power rifle scope and optic uses 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 change because it is fixed.
Info About Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification power levels. It will list the magnification amount in a format such as 2-10×32. These numbers indicate the magnification of the scope can be set between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adjustment is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some advised scope power levels and the ranges where they may be effectively used. Keep in mind that higher magnification optics will not be as effective as lower powered optics and scopes since increased magnification can be a negative thing in certain situations. The exact same idea applies to longer distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Lens Finishing for Optics
All modern rifle optic and scope lenses are layered. There are various types and qualities of glass finishes. Lens coating is an essential aspect of a rifle when contemplating luxury rifle optics and scope units. The lenses are one of the most critical parts of the scope considering they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface and improves anti glare capabilities from excess sunlight and color profiles.
About Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens coverings which use various procedures, elements, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating for Optics
Different optic lenses can likewise have different coverings used to them. All lenses normally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial 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 producers also make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has several treatments applied to the surfaces. If a lens gets multiple treatments, it can indicate that a company is taking multiple steps to combat different environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally doesn’t necessarily indicate the multi-coated lens is much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment techniques and the quality of glass used in building the rifle optic.
Hydrophobic Rifle Scope Lens Finishing
Water on a scope lens does not support retaining a clear sight picture through a scope at all. Lots of top of the line or premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Rifle Scope Installing Choices
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically are made in quick release variations which use manual levers which allow rifle operators to quickly mount and remove the optics.
Hex Key Scope Rings
Normal, clamp design 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 made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is fine for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be switched out if they all use a similar design mount. These types of mounts come in handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day on the range and your highly-priced optic by causing fogging and generating residue inside of the scope’s tube. Most scopes protect against humidity from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are worried about the scope still performing if it goes overboard and you can still recover the firearm.
Optic Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less affected by climate shifts and pressure distinctions from the outdoor environment which might potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
