What You Need to Know About Rifle Optics
Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnification by using a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate natural elements like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes and optics have about eleven parts which are located within and outside of the scope body. These parts include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other elements. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has determines where the reticle or crosshair lies in connection with the optic’s zoom. It literally suggests the reticle is behind or before the magnifying lens of the optic. Deciding on the most beneficial type of rifle glass is dependent on what kind of shooting you intend on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their target “hold over” as well as “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to remain at the exact same size in relation to the level of magnification being used. The outcome is that the reticle measurements change based on the magnification used to shoot over greater ranges given that the markings present various increments which vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These sorts of scopes work for:
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within much shorter distances and ranges
- Shooters who would like a clearer optic picture without space taken up by the larger sized FFP reticle
About Rifle Glass Zoom
The amount of magnification a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Single Power Lens Rifle Optics
A single power rifle scope or optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change since it is fixed.
Variable Power Lens Glass Info
Variable power rifle scopes can be tweaked between magnified levels. The power change is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Optics
Here are some recommended scope powers and the ranges where they may be successfully used. Consider that high power optics will not be as efficient as lower powered optics since too much zoom can be a bad thing. The same idea applies to extended ranges where the shooter needs to have enough power to see precisely where to properly aim the rifle at the target.
Optic Lens Covering
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of lens finishings. Lens coating can be an essential aspect of a rifle’s setup when thinking about high-end rifle optics and targeting equipment. The lenses are among the most significant pieces of the glass considering that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area and also assists with anti glare from excess sunrays and color visibility.
HD Versus ED Lens Coatings
Some rifle scope makers will also use “HD” or high-def lense finishings that use various processes, polarizations, rare earth compounds, and aspects to draw out separate color ranges and viewable target definition through the lens. This high-def finish is normally used with more costly high density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible around objects with hard edges and outlines as light hits the item from various angles.
Single Covering Versus Multi-Coating
Various optic lenses can also have different coatings applied to them. All lenses generally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finishing put on it so that the lens will be optimally functional in lots of kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can establish that a company is taking numerous steps to fight different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not necessarily mean the multi-coated lens is better than a single layered lens. Being “better” hinges on the producer’s lens treatment innovation and the quality of materials used in creating the rifle glass.
Anti-water Rifle Glass Lens Coating
Water on an optic’s lens does not assist with preserving a clear sight picture through an optic whatsoever. Many top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the surface of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Mounting options for scopes can be found in a few options. There are the basic scope rings which are individually mounted to the optic 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 permit rifle shooters to rapidly mount and dismount the optics.
Hex Key Rifle Glass Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is effective for rifle systems which need a durable, unfailing mount which will not change despite how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a specialized scope system on a far away scouting or tournament long gun which will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screws from backing out after they are installed securely in place. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Numerous scopes can also be switched out if they all use a similar style mount. These types of mounts come in handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another element of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less affected by condition alterations and pressure differences from the external environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
