What You Need to Know About Rifle Optics
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of various environmental factors like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have around eleven parts which are located within and externally on the optic. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. See all eleven parts of a rifle scope.
About Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has decides where the reticle or crosshair lies in regard to the scopes zoom. It literally means the reticle is behind or in front of the magnifying lens of the optic. Deciding upon the most suitable type of rifle scope is based upon what kind of hunting or shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who have an idea for their target “hold over” and also “lead” ratios for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within much shorter proximities and ranges
- Shooters who would like a clearer optic picture without space taken up by the larger size FFP reticle
Magnification for Rifle Glass
The quantity of magnification a scope provides is identified by the size, 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 Rifle Scope Info
A single power rifle scope and optic will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate given that it is fixed.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration like 2-10×32. These numbers suggest 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 adaptation is accomplished utilizing the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some suggested scope power levels and the distances where they could be efficiently used. Highly magnified glass will not be as beneficial as lower magnification optics considering too much zoom can be a negative aspect depending on your shooting distance. The very same idea applies to longer distances where the shooter needs adequate power to see where to properly aim the rifle at the target.
Lens Coating for Rifle Scopes
All state-of-the-art rifle optic lenses are layered. Lens coating can be a significant element of a rifle when looking at high end rifle optics and scope setups.
HD Versus ED Glass Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coatings which use various processes, aspects, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Optics
Various optic lenses can also have different coatings applied to them. All lenses normally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has had numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can show that a producer is taking several steps to fight various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally does not necessarily suggest the multi-coated lens will perform better than a single coated lens. Being “better” depends upon the producer’s lens treatment solutions and the quality of materials used in constructing the rifle glass.
Anti-water Finishing for Glass
Water on a lens doesn’t improve retaining a clear sight picture through an optic at all. Numerous top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface area of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Options for Installing Optics on Long Guns
Installing approaches for scopes can be found in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use manual levers which permit rifle shooters to rapidly mount and remove the scope.
Hex Key Optic Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 is developed for long range accuracy shooting. This type of scope mount is perfect for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types 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, multiple scopes can also be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts are useful and convenient for shooting platforms which are hauled around a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are employed between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle optic can destroy a day on the range and your costly optic by inducing fogging and producing residue within the scope tube. A lot of scopes protect against moisture from getting in the optical tube with a series of sealing O-rings which are waterproof. Typically, 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 sufficient wetness prevention for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are concerned about the scope still performing if it falls overboard and you can still rescue the firearm.
Rifle Glass Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less affected by condition alterations and pressure differences from the external environment which could possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
