What You Need to Know About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom by using a set of lenses inside the scope. The scope’s positioning can be dialed in to account for varied environmental considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes and optics have about 11 parts which are arranged within and externally on the scope. These parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. See all eleven parts of an optic.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle scope is based on what type of shooting you plan to do.
First Focal Plane Glass
First focal plane glass (FFP) include the reticle ahead of 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 amplified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who know their target “hold over” as well as “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. This induces the reticle to remain at the very same size relative to the volume of magnification being used. The outcome is that the reticle dimensions evolve based on the zoom used to shoot over longer distances considering that the reticle measurements represent various increments which can vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of glass work for:
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who choose a clearer optic sight picture without area used up by the larger size FFP reticle
The quantity of magnification a scope provides is identified by the size, thickness, 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 Glass Facts
A single power rifle optic and scope will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate given that it is a set power scope.
Variable Power Lens Optic Info
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification level in a format such as 2-10×32. These numbers imply the magnification of the scope could be set in between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is achieved by applying the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Optics
Here are some suggested scope power levels and the ranges where they could be efficiently used. High power scopes will not be as effective as lower magnification level glass because too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to longer distances where the shooter needs adequate power to see where to best aim the rifle.
Lens Finishing for Glass
All contemporary rifle optic and scope lenses are coated. There are various types and qualities of lens coverings. When considering luxury rifle optics and scope systems, Lens covering can be a vital component of defining the rifle’s capability. The lenses are among the most vital pieces of the optic since they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens exterior and improves anti glare capabilities from excess daylight and color profiles.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens finishes which use different techniques, chemicals, polarizations, and elements to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Info on Single Covering Versus Multi-Coating
Different optic lenses can likewise have various finishes applied to them. All lenses typically have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
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 lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope developer and how much money you spent for it. Both the manufacturer and amount are indicators 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 technology and the quality of products used in constructing the rifle scope.
About Hydrophobic Finish
Water on an optic’s lens does not improve retaining a clear sight picture through an optic at all. Lots of top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Choices for Mounting Scopes on Firearms
Mounting options for scopes come in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release versions which use toss levers which allow rifle operators to quickly mount and remove the glass.
Rifle Scope Mounting Solutions with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope mount is wonderful for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. A wide range of scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts are useful and convenient for rifles which are moved a lot, to remove the optic from the rifle for protection, or for scopes which are utilized in between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can mess up a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another part of preventing the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less impacted by condition shifts and pressure differences from the outdoor environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
