What You Need to Know About Rifle Optics
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by making use of a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of varied ecological things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle optics have around 11 parts which are located inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other parts. See all eleven parts of a scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the finest type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who know their target “hold over” and “lead” equations for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle to the rear of the magnification lens. This causes the reticle to remain at the same dimensions in relation to the quantity of zoom being used. The result is that the reticle dimensions shift based on the zoom employed to shoot over greater ranges considering that the markings present distinct increments which fluctuate with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular sorts of optics are convenient for:
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who select a clearer optic sight picture with less space used up by the larger sized FFP reticle
Magnification for Optics
The amount of scope zoom you require depends upon the kind of shooting you choose to do. Almost every type of rifle scope provides some level of magnification. The level of zoom a scope provides is determined by the diameter, thickness, and curvatures of the lens glass inside of the rifle optic. The zoom of the scope is the “power” of the glass. This denotes what the shooter is looking at through the scope is amplified times the power factor of what can generally be seen by human eyes.
Single Power Lens Scope Facts
A single power rifle optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust since it is set from the factory.
Info on Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a configuration such as 2-10×32. These numbers mean the magnification of the scope can be set in between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power shift is achieved by employing the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Ranges
Here are some suggested scope power settings and the ranges where they can be effectively used. High power optics will not be as effective as lower magnification level rifle scope glass since too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to longer ranges where the shooter needs sufficient power to see where to properly aim the rifle at the target.
Lens Coating for Optics
All top teir rifle optic and scope lenses are layered. Lens finishing can be a crucial aspect of a rifle when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope producers also use “HD” or high-def lens finishings that take advantage of different procedures, chemicals, components, and polarizations to extract separate colors and viewable definition through lenses. This high-def finishing is often used with increased density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around things with well defined outlines as light hits the item from certain angles.
Single Finishing Versus Multi-Coating for Optics
Various scope lenses can even have various finishings applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finish applied to it so that it will be optimally functional in many kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering 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 maker and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can show that a producer is taking numerous actions to combat various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not necessarily indicate the multi-coated lens will perform better than a single layered lens. Being “much better” depends upon the producer’s lens treatment innovation and the quality of glass used in building the rifle glass.
Hydrophobic Coating for Optics
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finish.
Scope Installation Alternatives
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release variations which use throw levers which allow rifle operators to quickly install and dismount the optics.
Scope Mounts with Hex Key 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope install is wonderful for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly 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 retaining accuracy. These kinds of mounts are useful and beneficial for shooting platforms which are shipped a lot, to remove the scope glass from the rifle for protection, or for scopes which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle glass can wreck a day on the range and your pricey optic by resulting in fogging and producing residue inside of the scope’s tube. Most scopes protect against humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Normally, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content prevention for conventional use rifles, unless you anticipate taking your rifle on a boat and are concerned about the scope still working if it goes over the side and you can still rescue the firearm.
Glass Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the optic is less influenced by temperature level shifts and pressure distinctions from the outside environment which might possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
