What You Need to Know About Rifle Optics

Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification by using a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of numerous ecological elements like wind and elevation decreases to account for bullet drop.

The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have around 11 parts which are found within and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle scopes.

Rifle Optic Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has determines where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It actually indicates the reticle is located behind or before the magnifying lens of the scope. Deciding on the most desired style of rifle glass depends upon what type of hunting or shooting you anticipate undertaking.

First Focal Plane Optic Info

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

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where computations are minimal
  • Experienced shooters who recognize their target “hold over” and “lead” correlations for their weapon
  • Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle

Second Focal Plane Optic Facts

Second focal plane scopes (SFP) include 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 types of shooting where shooters have increased time to make ballistic estimations
  • Shooting where most of the shots occur within shorter proximities and ranges
  • Shooters who want a clearer optic picture with less area taken up by the larger size FFP reticle

About Optic Zoom

The amount of scope magnification you require depends on the sort of shooting you like to do. Virtually every style of rifle glass offers some level of zoom. The volume of zoom a scope offers is identified by the dimension, density, and curves of the lenses inside of the rifle scope. The magnification level of the scope is the “power” of the scope. This signifies what the shooter is looking at through the scope is magnified times the power element of what can typically be seen by human eyes.

Fixed Power Lens Glass

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

Adjustable Power Lens Glass

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

Power Levels and Range Correlations

Here are some suggested scope power levels and the distances where they can be efficiently used. Bear in mind that higher power scopes will not be as practical as lower powered glass due to the fact that too much magnification can be a negative thing in certain situations. The exact same idea goes for longer distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.

Rifle Glass Lens Finish

All modern-day rifle scope lenses are coated. There are various types and qualities of coverings. When shopping for high end rifle targeting units, Lens covering can be a significant component of defining the capability of the rifle. The glass lenses are among the most crucial components of the optic considering they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens exterior and also helps with anti glare from refracted sunshine and color exposure.

HD Versus ED Scope Lens Coatings

Some optic producers will also use “HD” or high-def glass finishes which employ various processes, polarizations, rare earth compounds, and elements to extract numerous color ranges and viewable definition through the lens. This high-definition coating is frequently used with increased density glass which drops light’s ability to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around things with well defined shapes as light hits the item from particular angles.

Single Coating Versus Multi-Coating

Different optic lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finish placed on it so that the lens will be efficiently functional in numerous kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.

Single coated lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can shield 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 layered lens depends upon the scope manufacturer and how much money you spent for it. Both are indications of the lens quality.

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

Hydrophobic Optic Lens Coating

Water on a scope’s lens doesn’t assist with maintaining a clear sight picture through an optic whatsoever. Many top of the line and premium scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.

Alternatives for Installing Scopes on Firearms

Installing options for scopes come in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally can be found in quick release versions which use throw levers which allow rifle shooters to quickly mount and dismount the optics.

Optic Mounting Solutions with Hex Key Rings

Normal, 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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope mount is great for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Optic Mounting Solutions with Quick-Release Cantilever Rings

These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be swapped out on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These types of mounts come in practical for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for scopes which are used in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD

Info on Rifle Optic Tube Sealing and Gas Purging

Wetness inside your rifle scope can mess up a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Many scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.

Info Around Scope Tube Gas Purging

Another element of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the scope is less influenced by temperature alterations and pressure variations from the external environment which may potentially permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
