Rifle Scope Info
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification using a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of different natural elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have about 11 parts which are found within and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. Learn about the eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located relative to the optic’s zoom. It actually implies the reticle is located behind or ahead of the magnifying lens of the optic. Deciding upon the most desired kind of rifle glass depends upon what kind of shooting or hunting you anticipate undertaking.
Info About First Focal Plane Optics
First focal plane glass (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are low
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same size in connection with the amount of magnification being used. The final result is that the reticle dimensions adjust based upon the zoom chosen to shoot over longer ranges since the reticle markings represent different increments which vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These types of glass work for:
- Far away forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who like a clearer optic sight picture without space used up by the enlarged FFP reticle
About Rifle Optic Magnification
The quantity of magnification a scope provides is determined by the diameter, 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 Optics
A single power rifle optic or scope will have 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 type of scope can not adjust considering that it is set from the factory.
Variable Power Lens Optics
Variable power rifle scopes have adjustable power. It will note the magnification amount in a configuration such as 2-10×32. These numbers mean the magnification of the scope can be changed in between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adjustment is achieved by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Scope Power Level and Range Correlation
Here are some suggested scope power settings and the distances where they may be efficiently used. Consider that higher magnification optics and scopes will not be as practical as lower powered glass due to the fact that too much magnification can be a detractor. The same concept relates to extended distances where the shooter needs adequate power to see precisely where to properly aim the rifle.
Lens Covering for Rifle Scopes
All cutting-edge rifle scope and optic lenses are covered. Lens coating is an important aspect of a rifle’s setup when buying high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, chemicals, and elements to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Glass
Different optic lenses can likewise have various finishings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and how much you spent on it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Finishing for Rifle Optics
Water on a lens does not help with preserving 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 covering.
Optic Mounting Choices
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use manual levers which enable rifle operators to rapidly mount and dismount the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope install is great for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Several scopes can also be swapped 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 fasten nicely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving the original sighting settings. These types of mounts are useful and beneficial for rifles which are moved around a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day on the range and your costly optic by resulting in fogging and generating residue inside of the scope’s tube. A lot of optics prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are concerned about the scope still performing if it is submerged in water and you can still retrieve the rifle.
Rifle Glass Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less impacted by condition shifts and pressure differences from the external environment which may potentially enable 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.
