What You Need to Know About Scopes

Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by making use of a series of lenses within the scope. The scope’s alignment can be adapted to take into account varied environmental things like wind speed and elevation increases or decreases to account for bullet drop.

The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes have around 11 parts which are found within and outside of the scope. These parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.

Rifle Optic Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair is located in regard to the scopes magnification. It simply implies the reticle is situated behind or before the magnifying lens of the optic. Picking out the most suitable kind of rifle glass depends upon what kind of hunting or shooting you plan on undertaking.

Info About First Focal Plane Optics

Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:

  • Quick acquisition, long distance types of shooting
  • Shooting circumstances where calculations are small
  • Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their long gun
  • Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle

Second Focal Plane Optic Info

Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This induces the reticle to stay at the same scale in relation to the level of zoom being used. The result is that the reticle measurements shift based on the zoom employed to shoot over lengthier distances given that the reticle measurements present different increments which differ with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of optics are beneficial for:

  • Far away types of shooting where shooters have extra time to make ballistic computations
  • Shooting where most shots happen within shorter ranges and proximities
  • Shooters who select a clearer optic picture without area taken up by the enlarged FFP reticle

Ins and Outs of Rifle Optic Magnification

The amount of scope magnification you require depends upon the kind of shooting you would like to do. Nearly every style of rifle optic delivers some amount of zoom. The level of zoom a scope supplies is determined by the dimension, density, and curvatures of the lens glass inside of the rifle scope. The magnification level 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 element of what can usually be seen by human eyes.

Info About Fixed Power Lens Rifle Scopes

A single power rifle scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change considering that it is set from the factory.

Variable Power Lens Optic Details

Variable power rifle scopes use variable power levels. The power change is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.

Rifle Scope Power Level and Range Correlation

Here are some suggested scope power settings and the distances where they could be effectively used. Consider that high magnification scopes and optics will not be as effective as lower powered glass because too much zoom can be a bad thing. The same goes for extended distances where the shooter needs increased power to see exactly where to best aim the rifle.

Optic Lens Finishing

All top of the line rifle optic lenses are coated. Lens finishing is a vital element of a rifle system when purchasing high end rifle optics and scope equipment.

About Lens Coatings – HD Versus ED

Some scope companies even use “HD” or high-def lense finishings which make the most of various processes, polarizations, chemicals, and elements to enhance numerous colors and viewable definition through lenses. This HD coating is often used with higher density glass which drops light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be noticeable over items with hard edges and shapes as light hits the object from various angles.

Glass Lens Single Finish Versus Multi-Coating

Different scope lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or coating applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a coating applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.

Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it. Both the make and cost are indicators of the lens quality.

Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.

Anti-water Lens Finishing

Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic coating.

Options for Mounting Glass on Long Guns

Mounting approaches for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally can be found in quick release versions which use manual levers which permit rifle operators to rapidly mount and dismount the optics.

Hex Key Rifle Optic Ring Mounts

Standard, clamp-on style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These types of scope mounts use two independent rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This kind of scope mount is good for rifles which need to have a long lasting, rock solid mount which will not shift no matter just how much the scope is moved or abuse the rifle takes. These are the type of mounts you should get for a faithful scope setup on a reach out and touch someone hunting or tournament rifle that will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from wiggling out after they are installed firmly in place. An example of these mounting rings are the 30mm style from the Vortex Optics company. The set normally costs around $200 USD

Rifle Scope Mounts with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are handy for long guns which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between multiple rifles.

Rifle Scope Tube Sealing and Gas Purging

Wetness inside your rifle optic can destroy a day of shooting and your pricey optic by inducing fogging and producing residue inside of the scope’s tube. A lot of optics prevent humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Normally, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for basic use rifles, unless you intend on taking your rifle on boats and are worried about the optic still working if it goes over the side and you can still find the rifle.

Details on Rifle Glass Tube Gas Purging

Another component of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less affected by condition shifts and pressure variations from the outdoor environment which may possibly allow 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 look for.
