What You Need to Know About Rifle Glass

Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of various natural things like wind speed and elevation increases to make up for bullet drop.

The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes and optics have around 11 parts which are found inside and outside of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other components. Learn about the eleven parts of optics.

The Varieties of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair is located relative to the scopes magnifying adjustments. It literally implies the reticle is located behind or before the magnification lens of the scope. Deciding on the most beneficial style of rifle glass is dependent on what form of shooting you anticipate undertaking.

First Focal Plane Glass Info

First focal plane optics (FFP) come with the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These types of scopes work for:

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where computations are very little
  • Experienced shooters who recognize their target “hold over” and also “lead” ratios for their weapon
  • Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle

Second Focal Plane Scopes

Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.

  • Far away styles of shooting where shooters have extra time to make ballistic estimations
  • Shooting where most shots occur within shorter ranges and proximities
  • Shooters who select a clearer optic sight picture without area used up by the bigger FFP reticle

Details on Rifle Optic Magnification

The quantity of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.

Info on Fixed Power Lens Rifle Glass

A single power rifle scope comes with a zoom 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 type of scope can not adjust given that it is a set power scope.

Variable Power Lens Glass

Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification degree in a configuration such as 2-10×32. These numbers imply the zoom of the scope could be changed in between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power shift is accomplished by operating the power ring part of the scope near the rear of the scope by the eye bell.

The Power Level and Range of Glass

Here are some advised scope powers and the distances where they may be efficiently used. Remember that higher power optics will not be as effective as lower powered glass because excessive zoom can be a negative thing in certain situations. The same applies to extended ranges where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.

Details on Lens Coverings

All modern rifle scope lenses are layered. There are different types and qualities of glass lens finishes. When thinking about luxury rifle targeting setups, Lens covering can be a crucial aspect of defining the rifle’s capability. The glass lenses are one of the most key components of the scope as they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens surface area and assists with anti glare from excess sunshine and color perception.

HD Versus ED Lens Coatings

Some scope producers also use “HD” or high-definition lens finishings which use various techniques, components, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.

Single Finishing Versus Multi-Coating

Different scope lenses can also have different coatings applied to them. All lenses normally have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer 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” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.

Anti-water Lens Finishes

Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface area of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.

Optic Installing Alternatives

Installing solutions for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally are made in quick release versions which use throw levers which enable rifle operators to rapidly install and remove the optics.

Hex Key Rifle Glass Ring Mounting Solutions

Basic, clamp style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use double individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This form of scope mount is good for rifle systems which need a resilient, unfailing mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the style of mounts you should have for a faithful optics system on a reach out and touch someone hunting or tournament rifle which will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screws from wiggling out after they are mounted tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD

Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a similar style mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.

About Rifle Scope Tube Sealing and Gas Purging

Moisture inside your rifle scope can spoil a day on the range and your highly-priced optic by triggering fogging and making residue inside of the scope tube. Most optics prevent wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Usually, these optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are concerned about the optic still performing if it goes over the side and you can still retrieve the rifle.

Gas Purged Rifle Glass Tubes

Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less impacted by temperature changes and pressure variations from the outside environment which could possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
