What You Need to Know About Scopes
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses within the scope. The scope’s positioning can be adapted to take into account various natural considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have about 11 parts which are found within and externally on the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
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 is located relative to the optic’s zoom. It simply means the reticle is behind or ahead of the magnification lens of the scope. Picking the most reliable kind of rifle scope is dependent on what style of shooting you anticipate undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” ratios for their rifles
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnifying lens. This induces the reticle to remain at the very same overall size in relation to the volume of zoom being used. The effect is that the reticle measurements shift based on the zoom used to shoot over lengthier ranges considering that the markings represent various increments which vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of optics are convenient for:
- Far away types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who like a clearer optic picture without space used up by the bigger FFP reticle
Rifle Glass Zoom
The quantity of scope magnification you need is based on the style of shooting you want to do. Nearly every style of rifle scope offers some level of magnification. The volume of magnification a scope offers is established by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnification level of the optic is the “power” of the scope. This suggests what the shooter is aiming at through the scope is amplified times the power factor of what can usually be seen by human eyes.
Single Power Lens Glass
A single power rifle optic or 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 scope can not change since it is a fixed power scope.
About Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. These types of scopes will note the magnification degree in a configuration like 2-10×32. These numbers mean the magnification of the scope could be adjusted in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adaptation is accomplished by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Optics
Here are some advised scope power settings and the ranges where they could be successfully used. Highly magnified glass will not be as useful as lower magnification level rifle scope glass considering that too much magnification can be a negative aspect depending on your shooting distance. The exact same idea relates to extended ranges where the shooter needs to have sufficient power to see where to best aim the rifle.
Rifle Optic Lens Finishing
All contemporary rifle scope and optic lenses are covered in special coatings. There are various types and qualities of glass lens finishings. When researching high end rifle targeting units, Lens finishing can be an essential component of defining the capability of the rifle. The glass lenses are one of the most significant components of the glass as they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface area and also improves anti glare from excess light and color exposure.
HD Versus ED Lenses
Some scope producers likewise use “HD” or high-definition lens finishes which use various techniques, polarizations, chemicals, and aspects 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.
Single Optic Lens Finish Versus Multi-Coating
Different optic lenses can also have different finishes 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. This is since the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a covering applied to it so that the lens will be optimally functional in many kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Covering
Water on an optical lens doesn’t support preserving a clear sight picture through a scope in any way. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Rifle Optic Mounting Choices
Mounting solutions for scopes come in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release variations which use toss levers which permit rifle shooters to rapidly install and dismount the glass.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 are created for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day on the range and your highly-priced optic by triggering fogging and producing residue within the scope’s tube. Most optics protect against humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Normally, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still functioning if it goes overboard and you can still salvage the gun.
Details on Optic Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by condition changes and pressure differences from the outside environment which might potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
