What You Need to Know About Optics
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to account for varied ecological factors like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have around 11 parts which are found internally and outside of the optic. These parts consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the best type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Optic Facts
First focal plane scopes (FFP) feature the reticle before the magnifying lens. This induces the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who know their target “hold over” and also “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind 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.
- Long distance types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who prefer a clearer optic picture with less room used up by the larger sized FFP reticle
Magnification for Rifle Glass
The level of scope magnification you need on your glass depends upon the form of shooting you want to do. Almost every type of rifle scope offers some level of magnification. The amount of zoom a scope supplies is established by the dimension, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the optic is the “power” of the opic. This indicates what the shooter is aiming at through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Single Power Lens Optics
A single power rifle scope uses 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 zoom of this type of optic can not fluctuate considering that it is a set power scope.
Info on Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power adjustment is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Range Correlation
Here are some recommended scope powers and the ranges where they can be efficiently used. Highly magnified optics will not be as beneficial as lower magnification level optics since too much zoom can be a negative aspect depending on your shooting distance. The very same idea goes for extended distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle at the target.
Info on Rifle Scope Lens Covering
All modern rifle glass lenses are covered. Lens covering can be an important aspect of a rifle system when looking at high end rifle optics and scope setups.
HD Versus ED Lenses
Some optic companies will also use “HD” or high-def lens finishings that use various procedures, rare earth compounds, aspects, and polarizations to enhance a wide range of color ranges and viewable target visibility through lenses. This HD coating is often used with greater density lens glass which brings down light’s opportunity to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over objects with defined shapes as light hits the item from various angles.
Single Finish Versus Multi-Coating
Various scope lenses can even have different finishes applied to them. All lenses usually have at least some type of treatment or covering applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It needs to have a finishing applied to it so that the lens will be optimally functional in lots of types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer 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” coated. This suggests the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can establish that a company is taking multiple steps to fight different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily suggest the multi-coated lens is much better than a single covered lens. Being “better” depends upon the manufacturer’s lens treatment technology and the quality of products used in creating the rifle glass.
Anti-water Lens Coatings
Water on an optical lens doesn’t support maintaining a clear sight picture through an optic whatsoever. Many top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior of the Steiner optic lens so the H2O molecules 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 Installing Rifle Scopes on Firearms
Installing solutions for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release versions which use throw levers which allow rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Glass Rings
Standard, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use double detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This type of scope mount is exceptional for rifles which require a durable, unfailing mount which will not shift no matter how much the scope is moved or abuse the rifle takes. These are the style of mounts you really want to have for a specialized scope setup on a reach out and touch someone scouting or competitors firearm that will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screw threads from wiggling out after they are installed securely in place. An example of these rings are the 30mm style made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
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. A wide range of scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten tightly 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 while preserving precision. These kinds of mounts come in practical for rifles which are carried a lot, to take off the glass from the rifle for protection, or for aiming systems which are chosen for use in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can mess up a day of shooting and your costly optic by resulting in fogging and making residue within the scope’s tube. The majority of optics protect against humidity from getting in the scope tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content prevention for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are worried about the scope still working if it falls overboard and you can still rescue the firearm.
Gas Purged Glass Tubes
Another element of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the optic is less impacted by climate changes and pressure differences from the external environment which may possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
