What You Need to Know About Rifle Optics
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by making use of a series of lenses within the scope. The scope’s alignment can be adjusted to account for different environmental things like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes and optics have around eleven parts which are located within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials or turrets, 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. Opting for the optimal type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at one hundred yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who desire a clearer optic picture with less area used up by the bigger FFP reticle
Rifle Optic Magnification
The quantity of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info on Fixed Single Power Lens Scopes
A single power rifle optic and scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate given that it is a fixed power optic.
Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a format such as 2-10×32. These numbers imply the magnification of the scope could be set between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power manipulation is accomplished utilizing the power ring component of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power levels and the ranges where they can be effectively used. Highly magnified scopes will not be as efficient as lower powered optics because too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs enough power to see precisely where to properly aim the rifle.
Rifle Glass Lens Covering
All modern-day rifle optic and scope lenses are coated. There are different types and qualities of lens coatings. When considering luxury rifle scope devices, Lens coating can be a very important aspect of a rifle. The glass lenses are one of the most significant components of the glass because they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface and assists with anti glare capabilities from excess sunlight and color recognition.
HD Versus ED Lens Coatings
Some glass manufacturers also use “HD” or high-def lens finishings which employ different procedures, elements, polarizations, and chemical applications to enhance a wide range of color ranges and viewable definition through lenses. This high-def coating is normally used with greater density glass which brings down light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around items with defined shapes as light hits the item from various angles.
Single Coating Versus Multi-Coating
Different optic lenses can even have different coatings applied to them. All lenses typically have at least some type of treatment or finishing 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 finely tuned optic. It must have a finish put on it so that it will be efficiently functional in numerous kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope designer and how much you spent for it. Both are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Lens Coverings
Water on a lens doesn’t support maintaining a clear sight picture through a scope in any way. Many top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the surface area of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Scope Mounting Choices
Installing solutions for scopes are available in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use manual levers which allow rifle operators to rapidly mount and remove the glass.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp-on type mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use a pair of independent rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is effective for rifles which need to have a durable, rock solid mount which will not change no matter how much the scope is moved or jarring the rifle takes. These are the style of mounts you really want to have for a faithful optics system on a far away hunting or competition firearm that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from backing out after they are installed firmly in place. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Multiple scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
What to Know About Rifle Optic Tube Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less influenced by climate alterations and pressure differences from the external environment which may potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
