Rifle Scope Details
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of numerous environmental considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle optics have about 11 parts which are located within and externally on the scope. These scope parts include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It simply suggests the reticle is located behind or before the magnifying lens of the optic. Deciding on the most beneficial form of rifle optic depends on what type of hunting or shooting you intend on undertaking.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their rifles
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include 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 types of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who would like a clearer optic picture with less room used up by the larger size FFP reticle
Zoom for Glass
The amount of magnification a scope provides is figured out 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.
Info on Fixed Power Lens Scopes
A single power rifle scope uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust since it is a fixed power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will list the zoom amount in a configuration like 2-10×32. These numbers imply the zoom of the scope could be adjusted in between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Optics
Here are some suggested scope power levels and the distances where they may be effectively used. Keep in mind that higher magnification scopes and optics will not be as effective as lower powered optics and scopes since excessive magnification can be a negative thing in certain situations. The very same idea applies to extended ranges where the shooter needs increased power to see where to properly aim the rifle at the target.
Rifle Scope Lens Covering
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of glass lens finishes. When shopping for high end rifle optics and scope setups, Lens finishing can be a vital element of defining the rifle’s capability. The lenses are one of the most important pieces of the optic since they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens surface and also helps with anti glare capabilities from excess sunshine and color presence.
ED Versus HD Glass
Some scope manufacturers also use “HD” or high-definition lens coatings which use different procedures, chemicals, aspects, and polarizations to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Glass Lens Single Finishing Versus Multi-Coating
Different optic lenses can likewise have different finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope company and just how much you spent paying for it. Both the manufacturer and amount are signs of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can indicate that a company is taking several steps to combat different environmental factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not necessarily suggest the multi-coated lens will perform much better than a single layered lens. Being “better” hinges on the manufacturer’s lens treatment solutions and the quality of glass used in creating the rifle scope.
Anti-water Glass Lens Finish
Water on a scope’s lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Rifle Optic Installation Options
Mounting approaches for scopes can be found in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use throw levers which allow rifle operators to rapidly mount and remove the scope.
Hex Key Scope Ring Mounts
Standard, clamp-on type mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of independent rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This kind of scope mount is great for rifles which need to have a long lasting, hard use mount which will not change regardless of how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a faithful scope setup on a far away hunting or hard target interdiction firearm that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screw threads from backing out after they are mounted firmly in place. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove 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 handy for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less influenced by condition changes and pressure differences from the outdoor environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
