Rifle Glass Details

Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of separate environmental things like wind speed and elevation increases or decreases to account for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes and optics have about 11 parts which are found internally and outside of the optic. These parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other components. See all eleven parts of an optic.

The Styles of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle glass depends on what type of shooting you plan to do.

First Focal Plane Optic Info

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

  • Quick acquisition, far away kinds of shooting
  • Shooting situations where calculations are minor
  • Experienced shooters who recognize their aim point “hold over” plus “lead” correlations for their rifles
  • Shooters who don’t mind the reticle is bigger and uses up more visual sight space than a SFP reticle

About Second Focal Plane Scopes

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

  • Far away kinds of shooting where shooters have more time to make ballistic calculations
  • Shooting where most shots happen within much shorter ranges and proximities
  • Shooters who would like a clearer optic sight picture without area used up by the larger sized FFP reticle

Glass Zoom

The quantity of zoom a scope offers is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.

Fixed Single Power Lens Rifle Glass

A single power rifle optic will have a zoom number designator like 4×32. This suggests 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 considering that it is set from the factory.

Adjustable Power Lens Optics

Variable power rifle scopes have adjustable power. It will list the magnification level in a configuration like 2-10×32. These numbers indicate the magnification of the scope could be set in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power adjustment is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell piece.

Rifle Glass Power Level and Ranges

Here are some recommended scope powers and the ranges where they may be effectively used. Remember that high power scopes and optics will not be as practical as lower powered optics and scopes since excessive zoom can be a detractor. The very same idea relates to extended distances where the shooter needs to have increased power to see precisely where to best aim the rifle.

About Rifle Glass Lens Finish

All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass finishes. Lens finishing is an important element of a rifle’s setup when contemplating high-end rifle optics and targeting equipment. The glass lenses are among the most critical components of the glass considering they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses protects the lens exterior and even assists with anti glare capabilities from refracted direct sunlight and color visibility.

HD Versus ED Lenses

Some rifle scope makers additionally use “HD” or high-definition lense coatings that employ different processes, rare earth compounds, elements, and polarizations to draw out various color ranges and viewable target definition through the lens. This HD finish is commonly used with higher density glass which decreases light’s opportunity to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious around items with hard outlines as light hits the object from certain angles.

Single Covering Versus Multi-Coating for Optics

Various optic lenses can also have different coverings 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.

This lens treatment can safeguard the lens from scratches while decreasing 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 producer and how much you paid for it.

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

Anti-water Lens Coatings

Water on a scope’s lens does not support keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior surfaces of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.

Options for Installing Rifle Scopes on Long Guns

Installing approaches for scopes come in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically are made in quick release versions which use throw levers which enable rifle shooters to quickly mount and dismount the scopes.

Hex Key Glass Ring Mounts

Standard, 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 forms of scope mounts use double independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This type of scope mount is excellent for rifle systems which need to have a durable, unfailing mount which will not move no matter just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a devoted optics setup on a far away scouting or interdiction rifle that will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to protect against the hex screws from wiggling out after they are installed firmly in position. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD

Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transferred 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.

Optic Tube Sealing and Gas Purging

Moisture inside your rifle scope can wreck a day on the range and your highly-priced optic by resulting in fogging and developing residue within the scope tube. Most optics protect against wetness from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles, unless you intend on taking your rifle on boats and are worried about the optic still performing if it is submerged in water and you can still recover the gun.

Rifle Optic Gas Purging

Another part of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less impacted by condition alterations and pressure distinctions from the external environment which could possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
