What You Need to Know About Rifle Glass
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of various natural things like wind and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle optics have about 11 parts which are found within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has determines where the reticle or crosshair lies relative to the scopes zoom. It literally indicates the reticle is located behind or in front of the magnification lens of the scope. Picking out the very best form of rifle optic is based upon what style of hunting or shooting you anticipate undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Scope Details
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.
- Long distance styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who want a clearer optic sight picture without room used up by the bigger FFP reticle
Zoom for Rifle Scopes
The amount 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.
Single Power Lens Optics
A single power rifle optic or scope comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change since it is fixed.
About Adjustable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some recommended scope powers and the distances where they may be efficiently used. Keep in mind that higher magnification optics will not be as effective as lower magnification level glass since increased zoom can be a negative thing in certain situations. The same applies to longer ranges where the shooter needs sufficient power to see precisely where to properly aim the rifle.
Glass Lens Finishing
All contemporary rifle scope and optic lenses are coated. There are various types and qualities of lens finishings. When shopping for luxury rifle scope devices, Lens covering can be a critical aspect of defining the capability of the rifle. The glass lenses are among the most critical parts of the optic because they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens exterior as well as assists with anti glare from refracted light and color discernibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens coatings which use different processes, chemicals, polarizations, and components to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Coating Versus Multi-Coating
Various scope lenses can even have different coatings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered 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 lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and the amount you paid for it. Both the make and cost are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Covering for Glass
Water on a lens does not improve preserving a clear sight picture through an optic whatsoever. Lots of top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Scope Mounting Options
Installing solutions for scopes come in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also typically can be found in quick release variations which use toss levers which allow rifle operators to rapidly mount and dismount the scopes.
Scope Mounts with Hex Key Rings
Standard, clamp design 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope install is wonderful for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounts
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. A wide range of scopes can also be swapped 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 connect tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving the original sighting settings. These types of mounts are useful and convenient for shooting platforms which are hauled around a lot, to remove the optic from the rifle for protection, or for scopes which are utilized between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
What to Know About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your highly-priced optic by triggering fogging and developing residue within the scope tube. A lot of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Normally, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture avoidance for basic use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still working if it goes over the side and you can still find the firearm.
Scope Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less influenced by temperature level shifts and pressure differences from the outside environment which might possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
