What You Need to Know About Scopes
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by making use of a series of lenses within the scope. The scope’s positioning can be adapted to account for various ecological considerations like wind speed and elevation to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have about 11 parts which are found inside and externally on the scope body. These parts include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of a scope.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the best type of rifle glass is based on what type of shooting you plan to do.
About First Focal Plane Scopes
First focal plane optics (FFP) include the reticle ahead of the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who have an idea for their target “hold over” plus “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture with less room taken up by the enlarged FFP reticle
Rifle Scope Magnification
The quantity of scope magnification you need on your scope is based on the type of shooting you want to do. Almost every style of rifle optic gives some amount of zoom. The volume of zoom a scope supplies is determined by the dimension, thickness, and curves of the lenses within the rifle scope. The magnification level of the scope is the “power” of the glass. This denotes what the shooter is observing through the scope is magnified times the power factor of what can generally be seen by human eyes.
About Fixed Power Lens Rifle Glass
A single power rifle optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate given that it is set from the factory.
Variable Power Lens Scope Facts
Variable power rifle scopes use enhanced power. The power change is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Range Correlation
Here are some advised scope powers and the distances where they can be effectively used. Remember that higher magnification scopes and optics will not be as effective as lower magnification level scope and optics because excessive zoom can be a negative thing in certain situations. The exact same idea applies to longer distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
About Optic Lens Finishes
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of glass lens finishings. When thinking about high end rifle targeting devices, Lens finish can be a critical aspect of a rifle. The glass lenses are among the most key components of the optic considering 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 exterior and even assists with anti glare from refracted sunrays and color recognition.
ED Versus HD Rifle Glass
Some scope brands likewise use “HD” or high-definition lens coatings which use various processes, chemicals, polarizations, and components to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different coatings used to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope developer and the amount you paid for it. Both the manufacturer and amount are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. This means the lens has numerous treatments applied to the surfaces. If a lens gets several treatments, it can establish that a manufacturer is taking multiple actions to fight different natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not necessarily mean the multi-coated lens is better than a single covered lens. Being “better” is dependent on the producer’s lens treatment technology and the quality of glass used in constructing the rifle glass.
Hydrophobic Optic Lens Covering
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic coating.
Glass Mounting Choices
Mounting solutions for scopes can be found 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 different kinds of mounts also generally come in quick release variations which use manual levers which allow rifle operators to quickly install and dismount the glass.
Hex Key Rifle Glass Ring Mounting Solutions
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 two different 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 excellent for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. If they all use a similar design mount, several scopes can often be swapped out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in convenient for rifles which are transferred a lot, to remove the scope from the rifle for protection, or for aiming systems which are adopted between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It generally costs around $250 USD
What to Know About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Info on Glass Tube Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less impacted by temp shifts and pressure differences from the external environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
