Rifle Optic Info
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted for the consideration of varied environmental considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes and optics have about eleven parts which are located internally and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other parts. See all eleven parts of a scope.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has decides where the reticle or crosshair lies in relation to the optic’s magnification. It actually implies the reticle is located behind or in front of the magnification lens of the optic. Picking out the most reliable kind of rifle optic is based on what style of shooting or hunting you intend on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying 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 enhanced distance as they are at the non amplified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) come with the reticle behind the magnifying lens. This induces the reticle to stay at the exact same overall size in relation to the volume of zoom being used. The effect is that the reticle measurements adapt based on the zoom chosen to shoot over greater ranges because the reticle measurements present distinct increments which vary with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular kinds of scopes work for:
- Long distance types of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who prefer a clearer optic picture with less area taken up by the bigger FFP reticle
Ins and Outs of Rifle Glass Magnification
The amount of zoom 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.
Fixed Single Power Lens Rifle Scopes
A single power rifle scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power scope.
About Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power change is achieved by the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Glass
Here are some suggested scope power levels and the distances where they may be successfully used. Highly magnified optics will not be as effective as lower magnification optics because too much zoom can be a bad thing. The same relates to extended distances where the shooter needs enough power to see precisely where to best aim the rifle at the target.
Lens Coating for Rifle Glass
All state-of-the-art rifle scope lenses are coated. Lens covering is a significant aspect of a rifle system when looking into high end rifle optics and scope systems.
HD Versus ED Lenses
Some glass manufacturers additionally use “HD” or high-definition lense coatings that use different processes, polarizations, elements, and chemicals to enhance numerous color ranges and viewable definition through the lens. This high-definition finish is typically used with more costly, high density glass which brings down light’s capability to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often visible around things with hard edges and outlines as light hits the object from specific angles.
Single Finish Versus Multi-Coating for Scopes
Different optic lenses can likewise have various finishings applied to them. All lenses usually have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope developer and how much you spent paying for it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a company is taking several actions to fight various natural factors like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally does not always imply the multi-coated lens will perform better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of products used in creating the rifle glass.
Anti-water Lens Finishes
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Alternatives for Mounting Scopes on Firearms
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use manual levers which enable rifle shooters to quickly mount and remove the glass.
Hex Key Rifle Optic Ring Mounts
Normal, clamp style 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope mount is fine for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These types of mounts are useful and handy for shooting platforms which are transferred a lot, to remove the scope from the rifle for protection, or for optics which are chosen for use between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can mess up a day on the range and your expensive optic by inducing fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, these scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture content prevention for conventional use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the scope still functioning if it goes over the side and you can still rescue the gun.
Rifle Scope Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less influenced by temp alterations and pressure variations from the outdoor environment which may 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 good rifle scope to look for.
