What You Need to Know About Rifle Optics
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of different ecological aspects like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes have about 11 parts which are found within and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other elements. See all eleven parts of an optic.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the finest type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scope Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who understand their target “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of 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 reticle measurement.
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who choose a clearer optic picture with less area taken up by the larger size FFP reticle
Rifle Scope Magnification
The amount of magnification a scope provides is figured out by the size, 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 Optics
A single power rifle scope or optic will have a magnification number designator like 4×32. This suggests 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 because it is set from the factory.
Adjustable Power Lens Glass Facts
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some recommended scope power settings and the ranges where they can be efficiently used. Always remember that higher magnification scopes and optics will not be as practical as lower magnification level glass because increased magnification can be a negative thing in certain situations. The same relates to extended ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Finish for Rifle Scopes
All contemporary rifle optic and scope lenses are layered. There are different types and qualities of lens coverings. When researching luxury rifle targeting setups, Lens coating can be a critical component of a rifle. The glass lenses are among the most key components of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens exterior and helps with anti glare from refracted sunshine and color visibility.
Info on Lens Coatings – HD Versus ED
Some glass producers also use “HD” or high-definition glass finishes which take advantage of various procedures, elements, compounds, and polarizations to draw out different color ranges and viewable target visibility through the lens. This HD coating is often used with higher density lens glass which reduces light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible around things with hard edges and shapes as light hits the object from certain angles.
Single Glass Lens Coating Versus Multi-Coating
Various optic lenses can likewise have various coverings used to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 coated lens depends on the scope maker and how much money you spent paying for it. Both the make and cost are signs of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Scope Lens Finishing
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Optic Installing Options
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also typically can be found in quick release versions which use throw levers which allow rifle shooters to rapidly install and remove the scope.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use double independent rings to support the optic, and are normally made from 7075 T6 billet aluminum which are developed for far away precision shooting. This kind of scope mount is great for rifle systems which require a resilient, unfailing mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the style of mounts you should have for a dedicated optics setup on a long distance hunting or competitors rifle that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to protect against the hex screw threads from backing out after they are installed firmly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These kinds of mounts come in beneficial for shooting platforms which are moved a lot, to take off the optic from the rifle for protection, or for aiming systems which are adopted between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Optic Tube Gas Purging
Another component of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less affected by temperature shifts and pressure variations from the external environment which may possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
