Optic Information
Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through zoom using a series of lenses inside the scope. The scope’s alignment can be adapted for the consideration of numerous environmental considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes and optics have about 11 parts which are located inside and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle glass depends on what type of shooting you plan on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This causes the reticle to remain at the same overall size in connection with the quantity of zoom being used. The end result is that the reticle dimensions alter based upon the magnification employed to shoot over greater distances due to the fact that the markings represent various increments which fluctuate with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of scopes are convenient for:
- Far away forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who like a clearer optic picture with less room used up by the bigger FFP reticle
Zoom for Glass
The amount of magnification a scope offers 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 Power Lens Optics
A single power rifle optic or scope will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a set power scope.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification power levels. It will list the zoom amount in a format such as 2-10×32. These numbers suggest the magnification of the scope can be set between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adaptation is accomplished by working with the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Scopes
Here are some advised scope powers and the ranges where they could be efficiently used. Highly magnified optics will not be as beneficial as lower magnification glass considering that too much zoom can be a bad thing. The exact same concept relates to extended ranges where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Rifle Optic Lens Coating
All current rifle optic and scope lenses are layered. Lens finishing is a vital element of a shooting system when looking at high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens coatings which use various procedures, polarizations, elements, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” covered. This suggests the lens has had numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can prove that a maker is taking multiple steps to fight different environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also doesn’t always suggest the multi-coated lens is better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment innovation and the quality of components used in constructing the rifle optic.
Anti-water Finishing for Rifle Scopes
Water on an optic’s lens doesn’t assist with maintaining a clear sight picture through an optic whatsoever. Many top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Glass on Long Guns
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use manual levers which allow rifle operators to quickly install and remove the scopes.
Hex Key Glass Rings
Basic, clamp-on type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This kind of scope mount is ideal for rifles which need a durable, rock solid mount which will not shift no matter just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should get for a dedicated optics system on a far away hunting or interdiction firearm that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screws from wiggling out after they are installed securely in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts are handy for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between numerous rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your expensive optic by inducing fogging and generating residue inside of the scope tube. The majority of optics prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Generally, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles, unless you plan on taking your rifle on a boat and are concerned about the scope still working if it is submerged in water and you can still salvage the firearm.
Glass Gas Purging
Another component of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less influenced by temp alterations and pressure variations from the external environment which could potentially 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.
