Scope Facts
Rifle scopes permit you to specifically aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s alignment can be adapted to take into account varied environmental factors like wind and elevation to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the target. Most modern rifle optics have about 11 parts which are arranged internally and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has establishes where the reticle or crosshair lies in connection with the scopes magnification. It simply implies the reticle is located behind or ahead of the magnification lens of the optic. Picking the most effective kind of rifle optic depends on what style of hunting or shooting you intend on doing.
First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who know their aim point “hold over” and also “lead” ratios for their firearm
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who choose a clearer optic picture without space used up by the enlarged FFP reticle
Ins and Outs of Rifle Glass Magnification
The quantity of zoom a scope provides is identified by the size, thickness, 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 Optic Info
A single power rifle scope comes with 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 kind of optic can not fluctuate because it is a fixed power scope.
Variable Power Lens Scope Facts
Variable power rifle scopes can be changed between magnification increments. It will note the zoom level in a format like 2-10×32. These numbers indicate the magnification of the scope can be adjusted between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power modification is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some suggested scope power levels and the distances where they could be effectively used. Highly magnified scopes will not be as beneficial as lower powered rifle scope glass due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same concept relates to longer ranges where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
Rifle Glass Lens Covering
All contemporary rifle scope and optic lenses are layered. Lens coating can be a vital aspect of a rifle’s setup when looking into high end rifle optics and scope equipment.
HD Versus ED Rifle Optic Lens Coatings
Some optic companies additionally use “HD” or high-definition lense coatings that take advantage of various processes, polarizations, chemicals, and aspects to draw out numerous colors and viewable target visibility through lenses. This high-def finishing is normally used with greater density lens glass which brings down light’s capability to refract through the lens glass. Some scope brands use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard outlines as light hits the item from certain angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just 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 functional in lots of types of environments, degrees of light (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope company and the amount you paid for it. Both are indications of the lens quality.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finishing
Water on a lens does not assist with preserving 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 hydrophobic or hydrophilic finish which is water repellent.
Rifle Scope Installing Options
Installing approaches for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use toss levers which permit rifle operators to quickly mount and dismount the scopes.
Hex Key Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is perfect for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
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 before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Many scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Info on Glass Tube Gas Purging
Another component of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less impacted by temp shifts and pressure differences from the external environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
