Scope Info
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account separate ecological aspects like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle optics have around 11 parts which are arranged internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. See all eleven parts of an optic.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the best type of rifle scope depends on what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who understand their target “hold over” and “lead” relationships for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who choose a clearer optic sight picture without area used up by the larger size FFP reticle
Glass Zoom
The measure of scope magnification you need on your scope depends on the style of shooting you like to do. Practically every kind of rifle glass offers some amount of magnification. The level of zoom a scope gives is established by the dimension, thickness, and curves of the lens glass within the rifle optic. The magnification level of the scope is the “power” of the scope. This means what the shooter is checking out through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle scope uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification levels. It will note the zoom degree in a format like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power shift is accomplished by operating the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the ranges where they can be effectively used. Remember that higher magnification glass will not be as efficient as lower magnification level optics and scopes because excessive magnification can be a detractor. The exact same idea goes for longer ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
About Glass Lens Coatings
All modern rifle glass lenses are coated. Lens finishing can be a significant element of a rifle’s setup when looking at high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coverings which use different processes, elements, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can even have various coverings applied to them. All lenses normally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Because 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 efficiently functional in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope producer and just how much you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Details on Anti-water Finishing
Water on a scope lens doesn’t support keeping a clear sight picture through a scope whatsoever. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Glass on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the optics.
Hex Key Optic Ring Mounts
Normal, clamp design 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is fine for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounting Solutions 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. If they all use a comparable style mount, multiple scopes can often be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining accuracy. These types of mounts come in practical for rifles which are moved around a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized in between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Glass Tubes
Another part of preventing the accumulation of wetness 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 altered by climate shifts and pressure differences from the outside environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
