What You Need to Know About Scopes
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification using a set of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle scopes and optics have about 11 parts which are arranged within and on the exterior of the optic. These parts include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scope Facts
First focal plane glass (FFP) come with the reticle before the magnifying lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This induces the reticle to remain at the exact same scale in connection with the amount of magnification being used. The effect is that the reticle dimensions change based on the zoom employed to shoot over longer distances considering that the reticle markings represent different increments which change with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These varieties of glass are handy for:
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and spaces
- Shooters who would like a clearer optic picture with less area taken up by the larger size FFP reticle
Zoom for Glass
The amount of magnification a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Single Power Lens Optics
A single power rifle scope and optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change since it is set from the factory.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power change is handled using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they could be successfully used. Highly magnified scopes will not be as effective as lower powered glass since too much zoom can be a bad thing. The exact same concept relates to extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Optic Lens Coating
All modern-day rifle scope lenses are coated. There are different types and qualities of glass lens finishings. When shopping for high end rifle optical units, Lens finish can be an essential element of defining the rifle’s capability. The glass lenses are one of the most essential components of the optic given that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens exterior and helps with anti glare from excess sunrays and color presence.
About Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens finishings which use various processes, chemicals, aspects, and polarizations to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Details on Single Coating Versus Multi-Coating
Different optic lenses can also have different finishes used to them. All lenses typically have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This means the lens has several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can prove that a maker is taking several actions to fight different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily mean the multi-coated lens is better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment techniques and the quality of components used in building the rifle scope.
About Hydrophobic Finish
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Mounting Glass on Firearms
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally are made in quick release versions which use manual levers which permit rifle operators to quickly mount and dismount the glass.
Hex Key Scope Rings
Normal, clamp style 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long range accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched 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 allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining accuracy. These types of mounts are useful and practical for rifles which are shipped a lot, to remove the scope glass from the rifle for protection, or for optics which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the glass is less affected by condition changes and pressure variations from the outdoor environment which may possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
