What You Need to Know About Rifle Glass

Rifle scopes permit you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be adapted to take into account different ecological considerations like wind and elevation increases or decreases to make up for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have around eleven parts which are arranged within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. See all eleven parts of scopes.

The Varieties of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the best type of rifle scope depends on what type of shooting you plan to do.

About First Focal Plane Optics

Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes are practical for:

  • Quick acquisition, long distance kinds of shooting
  • Shooting scenarios where computations are minor
  • Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their rifles
  • Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle

Info on Second Focal Plane Glass

Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This triggers the reticle to remain at the very same overall size relative to the volume of zoom being used. The final result is that the reticle dimensions change based on the zoom used to shoot over lengthier ranges since the reticle measurements present various increments which vary with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These types of optics are useful for:

  • Far away styles of shooting where shooters have extra time to make ballistic computations
  • Shooting where most shots take place within shorter spaces and ranges
  • Shooters who want a clearer optic sight picture with less area taken up by the larger sized FFP reticle

Magnification for Rifle Optics

The extent of scope zoom you need on your optic depends upon the sort of shooting you like to do. Practically every style of rifle optic provides some degree of magnification. The level of magnification a scope gives is established by the size, density, and curvatures of the lens glass within the rifle scope. The magnification of the scope is the “power” of the opic. This means what the shooter is observing through the scope is amplified times the power aspect of what can usually be seen by human eyes.

Fixed Power Lens Scopes

A single power rifle optic uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change since it is set from the factory.

Variable Power Lens Scope Details

Variable power rifle scopes can be changed between magnification levels. It will list the magnification degree in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be adjusted in between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power modification is achieved by working with the power ring component of the scope near the rear of the scope by the eye bell piece.

The Power Level and Range of Optics

Here are some recommended scope power settings and the distances where they may be effectively used. Bear in mind that high power glass will not be as effective as lower powered scope and optics because too much zoom can be a negative thing in certain situations. The very same idea goes for longer distances where the shooter needs increased power to see where to properly aim the rifle at the target.

Rifle Optic Lens Coating

All top of the line rifle optic lenses are coated. Lens covering can be a crucial aspect of a rifle when looking at high end rifle optics and scope setups.

HD Versus ED Rifle Glass Lens Coatings

Some glass manufacturers will also use “HD” or high-definition lense finishings that apply various processes, aspects, chemical substances, and polarizations to draw out a wide range of colors and viewable target definition through the lens. This high-definition covering is commonly used with more costly high density lens glass which drops light’s capability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how 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 visible around items with well defined shapes as light hits the item from certain angles.

Glass Lens Single Finish Versus Multi-Coating

Various scope lenses can also have different coverings applied to them. All lenses generally have at least some kind of treatment or covering applied to them before 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 becomes part of the carefully tuned optic. It needs to have a finishing applied to it so that the lens will be efficiently functional in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.

Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope maker and the amount you spent on it. Both are indications of the lens quality.

Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.

Details on Anti-water Coating

Water on an optical lens does not assist with retaining a clear sight picture through a scope whatsoever. Numerous top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.

Alternatives for Mounting Optics on Long Guns

Installing solutions for scopes are available in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use throw levers which allow rifle shooters to quickly mount and dismount the scope.

Hex Key Optic Ring Mounts

Basic, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use double individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This kind of scope mount is great for rifles which need a long lasting, rock solid mount which will not move despite just how much the scope is moved or jarring the rifle takes. These are the design of mounts you should have for a specialized scope system on a far away scouting or hard target interdiction firearm which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screw threads from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD

Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings

These kinds of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving the original sighting settings. These kinds of mounts come in handy for rifles which are shipped a lot, to remove the scope glass from the rifle for protection, or for sight systems which are adopted between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD

Rifle Optic Tube Sealing and Gas Purging

Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by bringing about fogging and producing residue inside of the scope tube. Many scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.

Gas Purged Glass Tubes

Another part of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the optic is less altered by temperature level alterations and pressure distinctions from the outdoor environment which could potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
