Info Rifle Scopes
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification using a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate ecological considerations like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have around 11 parts which are arranged internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other elements. See all eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has determines where the reticle or crosshair lies in relation to the optic’s magnification. It actually indicates the reticle is located behind or before the magnification lens of the optic. Selecting the most reliable form of rifle scope is dependent on what variety of shooting you plan on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who have an idea for their target “hold over” plus “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnifying lens. This causes the reticle to stay at the exact same dimensions in relation to the quantity of magnification being used. The result is that the reticle dimensions shift based on the zoom employed to shoot over lengthier distances because the reticle markings represent different increments which change with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular styles of scopes are convenient for:
- Far away forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who desire a clearer optic sight picture without space used up by the enlarged FFP reticle
Rifle Glass Zoom
The quantity of zoom a scope supplies is determined 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 Glass Info
A single power rifle scope will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust since it is a fixed power optic.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification amount in a format such as 2-10×32. These numbers suggest the zoom of the scope can be set between 2x and 10x power. This also includes the powers in-between 2 and 10. The power shift is achieved by operating the power ring component of the scope near the back of the scope by the eye bell.
Rifle Optic Power Level and Range Correlation
Here are some suggested scope power levels and the ranges where they can be efficiently used. High power glass will not be as effective as lower magnification optics considering that too much magnification can be a bad thing. The same relates to extended distances where the shooter needs enough power to see where to properly aim the rifle.
Rifle Optic Lens Finishing
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of lens finishings. Lens finishing can be an important element of a rifle’s setup when thinking about high-end rifle optics and targeting systems. The lenses are one of the most significant pieces of the glass due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens exterior as well as helps with anti glare from refracted direct sunlight and color exposure.
ED Versus HD Glass
Some optic suppliers will also use “HD” or high-def lense coatings that take advantage of various procedures, rare earth compounds, polarizations, and components to extract separate colors and viewable definition through lenses. This high-def finish is often used with higher density glass which lowers light’s capability to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over items with well defined outlines as light hits the object from certain angles.
Glass Lens Single Finish Versus Multi-Coating
Different scope lenses can even have different finishes applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing placed on it so that it will be optimally functional in numerous types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing 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 upon the scope maker and how much you spent paying for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Scope Lens Coating
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water finish.
Options for Installing Rifle Glass on Firearms
Mounting options for scopes are available in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use toss levers which permit rifle shooters to quickly mount and remove the scopes.
Hex Key Rifle Glass Ring Mounting Solutions
Basic, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This form of scope mount is ideal for rifles which are in need of a durable, unfailing mount which will not change regardless of just how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a specialized optics system on a reach out and touch someone hunting or interdiction firearm that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to protect against the hex screws from backing out after they are mounted firmly in position. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. Several scopes can also be switched out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top type Picatinny rail. This permits 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 beneficial for rifles which are transferred a lot, to remove the scope from the rifle for protection, or for optics which are employed between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can wreck a day on the range and your pricey optic by inducing fogging and creating residue within the scope tube. The majority of optics protect against wetness from getting in the scope tube with a system of sealing O-rings which are waterproof. Generally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle boating and are worried about the optic still working if it goes overboard and you can still recover the rifle.
Optic Gas Purging
Another element of avoiding the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less altered by condition changes and pressure variations from the external environment which may potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
