What You Need to Know About Glass

Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to account for numerous environmental factors like wind and elevation 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 via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes have around 11 parts which are found within and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.

Rifle Scope Types

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the optimal type of rifle glass is based around what type of shooting you plan on doing.

First Focal Plane Scope Info

Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:

  • Quick acquisition, long distance types of shooting
  • Shooting circumstances where calculations are very little
  • Experienced shooters who know their target “hold over” plus “lead” relationships for their long gun
  • Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle

Second Focal Plane Scope Facts

Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This triggers the reticle to stay at the very same overall size relative to the quantity of magnification being used. The final result is that the reticle dimensions adjust based upon the zoom used to shoot over longer ranges because the markings represent distinct increments which vary with the zoom level. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of optics work for:

  • 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 would like a clearer optic picture with less area taken up by the larger sized FFP reticle

Optic Magnification

The level of scope magnification you need on your optic is based on the style of shooting you intend to do. Pretty much every style of rifle glass supplies some level of zoom. The quantity of zoom a scope offers is identified by the diameter, density, and curves of the lenses within the rifle optic. The magnifying level of the optic is the “power” of the opic. This denotes what the shooter is observing through the scope is magnified times the power aspect of what can usually be seen by human eyes.

Single Power Lens Scope Info

A single power rifle optic or scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is set from the factory.

Info About Variable Power Lens Rifle Glass

Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification amount in a format such as 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This always involves the power levels in-between 2 and 10. The power shift is accomplished by employing the power ring component of the scope near the rear of the scope by the eye bell piece.

Power and Range Correlations

Here are some suggested scope power levels and the distances where they can be efficiently used. Consider that higher magnification optics will not be as efficient as lower powered optics due to the fact that excessive zoom can be a bad thing. The exact same concept relates to extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle.

Lens Covering for Rifle Glass

All top of the line rifle glass lenses are covered. Lens finishing can be an important aspect of a rifle when looking into high end rifle optics and scope systems.

HD Versus ED Lenses

Some glass producers additionally use “HD” or high-def lense finishings that make the most of different processes, polarizations, chemicals, and elements to enhance different color ranges and viewable target definition through lenses. This high-definition finish is typically used with higher density glass which brings down light’s ability to refract through the lens glass. Some scope vendors use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be noticeable around things with hard edges and shapes as light hits the object from various angles.

Info on Single Coating Versus Multi-Coating

Different optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.

Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing 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 upon the scope developer and how much you spent for it. The scope’s maker and cost are indications of the lens quality.

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

Hydrophobic Lens Finishes

Water on a lens does not assist with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.

Rifle Optic Mounting Choices

Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally come in quick release variations which use toss levers which permit rifle shooters to quickly mount and remove the scope.

Hex Key Rifle Optic Rings

Standard, clamp-on style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This type of scope mount is good for rifle systems which need to have a long lasting, rock solid mount which will not change regardless of how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a faithful optics setup on a long distance scouting or interdiction rifle which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD

Quick-Release Cantilever Scope Ring Mounting Solutions

These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles.

Glass Tube Sealing and Gas Purging

Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. The majority of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.

Rifle Glass Gas Purging

Another component of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less impacted by temperature level shifts and pressure variations from the external environment which may possibly permit 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.
