Info About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by making use of a series of lenses within the scope. The scope’s positioning can be adapted to account for numerous ecological considerations like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on 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 contemporary rifle scopes have around 11 parts which are found inside and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
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 on what type of shooting you plan to do.
First Focal Plane Scope Info
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who understand their target “hold over” and “lead” correlations for their firearm
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within much shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without area used up by the bigger FFP reticle
Rifle Optic Magnification
The amount of magnification a scope offers is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not change because it is a fixed power scope.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power change is performed using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some suggested scope power settings and the distances where they could be efficiently used. High power glass will not be as efficient as lower magnification scopes considering that too much magnification can be a negative aspect depending on your shooting distance. The exact same idea goes for longer ranges where the shooter needs to have enough power to see precisely where to properly aim the rifle.
Details on Rifle Scope Lens Finishing
All modern-day rifle scope and optic lenses are coated. Lens finishing is an important element of a shooting platform when purchasing high end rifle optics and scope setups.
Info on Lens Coatings – HD Versus ED
Some optic manufacturers will also use “HD” or high-def glass coatings which apply various procedures, polarizations, chemicals, and elements to extract separate colors and viewable target definition through the lens. This HD finish is often used with increased density glass which decreases light’s opportunity to refract by means of the lens glass. Some scope vendors 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 similarly called color distortion or fringing. Chromatic aberration is often visible around things with defined outlines as light hits the object from various angles.
Rifle Optic Lens Single Finish Versus Multi-Coating
Different scope lenses can also have various finishings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in numerous kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing 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 spent on it. Both are indications of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Lens Finish
Water on a scope’s lens doesn’t help with retaining a clear sight picture through an optic whatsoever. Many top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic finish. 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 result is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Installing Rifle Scopes on Firearms
Mounting approaches for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually are made in quick release versions which use throw levers which enable rifle shooters to rapidly install and dismount the scope.
Hex Key Glass Rings
Basic, clamp-on design mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use two individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is exceptional for rifles which need a resilient, rock solid mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a specialized optics system on a far away hunting or competitors firearm that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to protect against the hex screws from wiggling out after they are mounted safely in place. An example of these rings are the 30mm type made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These kinds of mounts come in handy for rifles which are moved a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are used between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle scope can destroy a day of shooting and your expensive optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another part of preventing the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less impacted by condition shifts and pressure distinctions from the external environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
