What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by making use of a set of lenses within the scope. The scope’s positioning can be adapted to take into account separate ecological considerations like wind and elevation increases 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 using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes and optics have about eleven parts which are arranged internally and externally on the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. See all eleven parts of a scope.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the optimal type of rifle glass depends on what type of shooting you plan on doing.
Info About First Focal Plane Glass
First focal plane scopes (FFP) include the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are low
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their weapon
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
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 would be 1/5th of the non “zoom” tick measurement.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who would like a clearer optic picture with less room taken up by the larger sized FFP reticle
Magnification for Scopes
The extent of scope magnification you need on your glass depends upon the type of shooting you intend to do. Pretty much every type of rifle scope provides some amount of zoom. The volume of magnification a scope delivers is identified by the diameter, thickness, and curves of the lens glass within the rifle optic. The magnification of the scope is the “power” of the glass. This means what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Power Lens Rifle Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change considering that it is a fixed power optic.
Info on Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is handled by using the power ring part of the scope near the back of the scope by the eye bell.
Scope Power Level and Ranges
Here are some advised scope powers and the ranges where they can be efficiently used. Remember that higher magnification optics and scopes will not be as efficient as lower magnification level optics due to the fact that increased zoom can be a negative thing in certain situations. The same concept goes for longer ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
About Lens Coatings
All modern rifle optic lenses are coated. Lens covering is an essential aspect of a rifle system when looking into high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some glass companies will also use “HD” or high-definition glass coverings that make the most of various processes, polarizations, chemicals, and aspects to enhance separate color ranges and viewable target visibility through the lens. This high-definition coating is often used with greater density glass which lowers light’s potential to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often visible over items with hard edges and outlines as light hits the object from certain angles.
Single Scope Lens Covering Versus Multi-Coating
Various optic lenses can likewise have different coatings applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing glare and other less advantageous 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 you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Rifle Glass Lens Hydrophobic Finishing
Water on a scope lens doesn’t improve keeping a clear sight picture through an optic in any way. Lots of top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Alternatives for Mounting Glass on Firearms
Installing approaches for scopes come in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release variations which use throw levers which allow rifle operators to rapidly mount and dismount the scope.
Glass Mounting Solutions with Hex Key Rings
Normal, clamp design 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 made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is great for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounts with Quick-Release Cantilever 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 comparable design 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 fasten tightly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These types of mounts come in beneficial for shooting platforms which are carried a lot, to remove 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 manufacturer. It typically costs around $250 USD
Info Around Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day on the range and your pricey optic by resulting in fogging and creating residue within the scope’s tube. A lot of optics protect against moisture from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard watercrafts and are worried about the optic still functioning if it falls overboard and you can still salvage the rifle.
Gas Purged Optic Tubes
Another component of avoiding the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the glass is less altered by temperature changes and pressure distinctions from the external environment which could potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
