Information Rifle Optics

Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of different environmental aspects like wind and elevation decreases to account for bullet drop.

The scope’s purpose is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have about eleven parts which are found within and externally on the optic. These scope parts include the rifle scope’s body, lenses, windage turrets, 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. Opting for the best type of rifle scope is based on what type of shooting you plan to do.

First Focal Plane Glass Info

Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:

  • Quick acquisition, far away types of shooting
  • Shooting scenarios where computations are very little
  • Experienced shooters who know their aim point “hold over” and also “lead” relationships for their rifles
  • Shooters who do not mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle

Info on Second Focal Plane Scopes

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

  • Long distance forms of shooting where shooters have additional time to make ballistic estimations
  • Shooting where most of the shots happen within shorter ranges and distances
  • Shooters who prefer a clearer optic sight picture without area used up by the enlarged FFP reticle

Scope Zoom

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

About Single Power Lens Rifle Glass

A single power rifle scope and optic comes with a zoom 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 optic can not fluctuate considering that it is set from the factory.

Adjustable Power Lens Optics

Variable power rifle scopes can be tweaked between magnified levels. The power change is handled using the power ring part of the scope near the back of the scope by the eye bell.

Power and Range

Here are some suggested scope power settings and the ranges where they can be efficiently used. Keep in mind that high power optics will not be as effective as lower powered glass because increased magnification can be a negative thing in certain situations. The same goes for extended distances where the shooter needs to have increased power to see where to properly aim the rifle at the target.

Info on Rifle Optic Lens Coating

All top of the line rifle scope lenses are layered. Lens finish is a crucial aspect of a shooting platform when buying high end rifle optics and scope setups.

Info on Optic Lens Coatings – HD Versus ED

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

Single Finishing Versus Multi-Coating

Various scope lenses can even have different finishings applied to them. All lenses normally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.

This lens treatment can offer protection to 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 layered lens depends on the scope manufacturer and how much you paid for it.

Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This means the lens has had multiple treatments applied to them. If a lens receives several treatments, it can indicate that a manufacturer is taking several actions to fight different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally doesn’t necessarily suggest the multi-coated lens is much better than a single coated lens. Being “better” depends upon the manufacturer’s lens treatment techniques and the quality of products used in building the rifle optic.

Hydrophobic Lens Finishes

Water on an optical lens doesn’t help with preserving a clear sight picture through an optic at all. Numerous top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.

Choices for Mounting Scopes on Long Guns

Mounting solutions for scopes can be found in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release versions which use toss levers which allow rifle shooters to quickly install and remove the glass.

Rifle Glass Mounts with Hex Key Rings

Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.

Scope Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Numerous scopes can even be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.

What to Know About Rifle Scope Tube Sealing and Gas Purging

Wetness inside your rifle optic can spoil a day on the range and your costly optic by resulting in fogging and creating residue within the scope tube. The majority of scopes prevent moisture from entering the scope 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 avoidance for basic use rifles, unless you intend on taking your rifle sailing and are concerned about the scope still working if it is submerged in water and you can still salvage the firearm.

Scope Gas Purging

Another element of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the scope is less impacted by temperature level alterations and pressure distinctions from the outside environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
