Rifle Optic Info

Rifle scopes permit you to precisely aim a rifle at various 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 inside the scope. The scope’s alignment can be dialed in for consideration of numerous environmental elements like wind and elevation to account for bullet drop.

The scope’s purpose is to help the shooter understand exactly 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 point of impact. Many contemporary rifle scopes and optics have about 11 parts which are located within and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.

Rifle Glass Varieties

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

First Focal Plane Optic Facts

First focal plane optics (FFP) include the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:

  • Quick acquisition, far away types of shooting
  • Shooting situations where computations are small
  • Experienced shooters who understand their target “hold over” and also “lead” equations for their long gun
  • Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle

About Second Focal Plane Optics

Second focal plane scopes (SFP) include the reticle behind 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 measurement.

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

Details on Optic Zoom

The extent of scope magnification you need on your optic is based on the form of shooting you intend to do. Nearly every kind of rifle optic offers some degree of magnification. The quantity of zoom a scope delivers is established by the size, density, and curvatures of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the scope. This implies what the shooter is observing through the scope is magnified times the power factor of what can generally be seen by human eyes.

Single Power Lens Glass Details

A single power rifle optic and scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is fixed.

Variable Power Lens Rifle Glass Facts

Variable power rifle scopes can be tweaked between magnified settings. The power modification is achieved by using the power ring part of the scope near the back of the scope by the eye bell.

The Power Level and Range Correlation of Optics

Here are some suggested scope power levels and the distances where they can be effectively used. Keep in mind that higher magnification glass will not be as effective as lower magnification level optics and scopes due to the fact that excessive zoom can be a bad thing. The same goes for extended distances where the shooter needs increased power to see where to best aim the rifle at the target.

About Rifle Glass Lens Finish

All top of the line rifle scope and optic lenses are covered. Lens finishing can be an essential aspect of a shooting platform when looking at high end rifle optics and scope systems.

Details on Scope Lens Coatings – HD Versus ED

Some glass manufacturers additionally use “HD” or high-definition lens finishes that make the most of different processes, chemicals, aspects, and polarizations to enhance various colors and viewable target definition through the lens. This HD covering is normally used with increased density glass which decreases light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be obvious around items with defined outlines as light hits the item from particular angles.

Single Coating Versus Multi-Coating

Different optic lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before they are 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 carefully tuned optic. It must have a covering placed on it so that the lens will be efficiently functional in numerous kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.

This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.

Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This implies the lens has several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can establish that a company is taking several actions to fight various environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the producer’s lens treatment innovation and the quality of glass used in building the rifle optic.

Hydrophobic Lens Finishes

Water on a scope lens does not support preserving a clear sight picture through an optic at all. Numerous top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.

Choices for Mounting Rifle Optics on Firearms

Installing options for scopes can be found in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use toss levers which permit rifle operators to quickly mount and dismount the scope.

Hex Key Rifle Scope Ring Mounting Solutions

Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This type of scope mount is very good for rifles which need a durable, rock solid mount which will not shift despite how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful scope system on a long distance scouting or sniper competition rifle that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screw threads from wiggling out after they are mounted safely in place. An example of these rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD

Quick-Release Cantilever Glass Rings

These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a similar style mount, a number of scopes can also be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts come in handy for rifles which are transported a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are used between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD

Rifle Optic Tube Sealing and Gas Purging

Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.

What to Know About Optic Tube Gas Purging

Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less influenced by temperature changes and pressure differences from the outside environment which could possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
