Rifle Optic Details
Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification using a series of lenses within the scope. The scope’s alignment can be dialed in to take into account different natural aspects like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle scopes and optics have around eleven parts which are found internally and outside of the scope body. These parts consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other components. Learn about the eleven parts of glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has determines where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It literally suggests the reticle is located behind or ahead of the magnification lens of the optic. Deciding on the most desired type of rifle optic is based on what style of shooting or hunting you anticipate undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their aim point “hold over” and also “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who choose a clearer optic picture without area used up by the enlarged FFP reticle
Ins and Outs of Glass Magnification
The extent of scope zoom you need on your scope depends upon the style of shooting you like to do. Practically every type of rifle optic supplies some level of magnification. The quantity of zoom a scope offers is identified by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnification level of the optic is the “power” of the scope. This indicates what the shooter is aiming at through the scope is magnified times the power element of what can typically be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle optic and scope uses a magnification number designator like 4×32. This implies 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 because it is a set power scope.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration like 2-10×32. These numbers mean the magnification of the scope could be adjusted between 2x and 10x power. This always involves the powers in-between 2 and 10. The power manipulation is achieved by applying the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Glass Power and Range Correlation
Here are some advised scope power settings and the distances where they can be efficiently used. High power rifle scope glass will not be as beneficial as lower powered optics since too much magnification can be a negative aspect depending on your shooting distance. The exact same concept goes for longer ranges where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Rifle Scope Lens Coating
All modern-day rifle glass lenses are coated. Lens coating can be an essential element of a rifle when looking into high end rifle optics and scope equipment.
ED Versus HD Scopes
Some glass manufacturers additionally use “HD” or high-def lens finishes that employ different processes, aspects, polarizations, and chemical applications to draw out numerous colors and viewable target visibility through lenses. This high-definition coating is often used with greater density glass which reduces light’s potential to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be noticeable around things with hard edges and shapes as light hits the item from certain angles.
Single Glass Lens Coating Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a covering placed on it so that it will be efficiently functional in lots of types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard 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 covered lens depends on the scope maker and the amount you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Rifle Scope Lens Finishing
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic covering.
Choices for Mounting Rifle Scopes on Firearms
Mounting solutions for scopes come in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Hex Key Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Glass Tube Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less affected by temp changes and pressure variations from the external environment which could potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
