Scope Details
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of varied natural things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have around eleven parts which are arranged inside and outside of the optic. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It simply means the reticle is located behind or in front of the magnifying lens of the scope. Picking the most effective sort of rifle glass depends on what form of shooting you plan on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are very little
- Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who desire a clearer optic sight picture with less area used up by the larger size FFP reticle
About Rifle Glass Magnification
The level of scope magnification you need depends upon the kind of shooting you want to do. Practically every style of rifle scope supplies some degree of magnification. The volume of zoom a scope delivers is established by the diameter, thickness, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This indicates what the shooter is observing through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate since it is a fixed power scope.
Info on Variable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power adjustment is handled by the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Glass
Here are some suggested scope powers and the ranges where they could be successfully used. Consider that higher power scopes and optics will not be as effective as lower magnification level scopes since excessive magnification can be a negative thing in certain situations. The very same idea relates to longer ranges where the shooter needs to have enough power to see where to best aim the rifle at the target.
Details on Rifle Glass Lens Finish
All modern-day rifle glass lenses are coated. Lens coating can be a significant aspect of a rifle system when thinking about high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle glass manufacturers also use “HD” or high-def lens finishes which employ different procedures, chemicals, polarizations, and components to extract various colors and viewable target visibility through the lens. This high-def finishing is typically used with greater density glass which decreases light’s potential to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over things with well defined shapes as light hits the object from certain angles.
Single Coating Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses normally have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing 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 designer and how much you spent on it. Both the make and cost are indicators of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Coverings
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Mounting Scopes on Long Guns
Mounting solutions for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use throw levers which enable rifle operators to quickly mount and remove the scope.
Hex Key Optic Ring Mounting Solutions
Standard, 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 is developed for long range precision shooting. This type of scope install is perfect for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a similar design mount, a number of scopes can often be swapped out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These kinds of mounts come in beneficial for shooting platforms which are hauled around a lot, to remove the optic from the rifle for protection, or for sight systems which are chosen for use in between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day on the range and your pricey optic by causing fogging and generating residue within the scope tube. Most optics protect against humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture avoidance for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the scope still performing if it goes overboard and you can still recover the gun.
Info Around Glass Tube Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the optic is less altered by temperature changes and pressure differences from the external environment which could possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
