Rifle Optic Details
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by using a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account separate natural considerations like wind and elevation decreases to account 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 seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have about eleven parts which are arranged within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. Learn about the eleven parts of glass.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has determines where the reticle or crosshair lies in regard to the optic’s magnification. It literally indicates the reticle is behind or in front of the magnifying lens of the optic. Deciding on the most suitable sort of rifle optic depends upon what sort of hunting or shooting you plan on doing.
First Focal Plane Glass
First focal plane glass (FFP) include the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who understand their aim point “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter distances and ranges
- Shooters who like a clearer optic picture with less room taken up by the enlarged FFP reticle
Ins and Outs of Scope Zoom
The measure of scope zoom you need on your scope depends upon the style of shooting you want to do. Pretty much every type of rifle optic gives some amount of zoom. The amount of magnification a scope offers is determined by the dimension, thickness, and curvatures of the lenses within the rifle optic. The magnifying level of the scope is the “power” of the scope. This denotes what the shooter is looking at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Single Power Lens Glass
A single power rifle optic and scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change given that it is a fixed power optic.
Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will note the magnification level in a format like 2-10×32. These numbers indicate the zoom of the scope could be set in between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power adaptation is achieved using the power ring part of the scope near the rear of the scope by the eye bell piece.
Scope Power Level and Ranges
Here are some advised scope powers and the distances where they may be effectively used. Highly magnified rifle scope glass will not be as useful as lower magnification level optics since too much magnification can be a negative aspect depending on your shooting distance. The same concept relates to extended distances where the shooter needs enough power to see where to properly aim the rifle.
About Lens Coatings
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of lens coverings. When looking at luxury rifle optics and scope units, Lens finishing can be a very important element of a rifle. The glass lenses are one of the most essential pieces of the scope given that they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface as well as improves anti glare capabilities from excess natural light and color exposure.
Details on Optic Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens finishes which use different methods, components, chemicals, 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.
Details on Single Coating Versus Multi-Coating
Various optic lenses can even have various coatings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing 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 makers likewise make it a point to define if their optic lenses are covered or “multi” coated. This means the lens has had several treatments applied to the surfaces. If a lens receives multiple treatments, it can prove that a manufacturer is taking several actions to fight various natural factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also doesn’t always indicate the multi-coated lens is much better than a single coated lens. Being “much better” depends on the maker’s lens treatment technology and the quality of glass used in constructing the rifle scope.
About Anti-water Finishing
Water on an optical lens doesn’t assist with preserving a clear sight picture through an optic at all. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Optic Installation Choices
Installing options for scopes can be found in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use toss levers which allow rifle operators to quickly install and remove the scopes.
Hex Key Optic Rings
Standard, 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope install is excellent for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a similar design mount. These types of mounts are handy for rifle platforms which are transported a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Optic Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less affected by climate shifts and pressure variations from the external environment which may possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
