Facts About Rifle Scopes
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target over a range. They do this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s alignment can be dialed in for consideration of numerous environmental factors like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes have around eleven parts which are arranged internally and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. See all eleven parts of optics.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle optic depends on what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This induces the reticle to remain at the exact same size in connection with the level of magnification being used. The outcome is that the reticle dimensions shift based upon the magnification used to shoot over greater distances since the markings represent different increments which can vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular varieties of glass are beneficial for:
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who want a clearer optic sight picture with less space taken up by the enlarged FFP reticle
Zoom for Rifle Scopes
The quantity of zoom a scope provides is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Rifle Optics
A single power rifle optic or scope comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust since it is fixed.
About Adjustable Power Lens Scopes
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some advised scope power settings and the distances where they could be efficiently used. High power rifle scope glass will not be as effective as lower magnification glass considering that too much zoom can be a bad thing. The same concept goes for extended ranges where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
Scope Lens Finish
All present day rifle optic and scope lenses are coated. Lens finishing can be a vital element of a rifle when purchasing high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some rifle scope companies even use “HD” or high-def lense finishes that take advantage of different procedures, chemicals, components, and polarizations to extract various color ranges and viewable target definition through the lens. This high-definition covering is commonly used with increased density lens glass which decreases light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with well defined shapes as light hits the object from certain angles.
Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses typically have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less useful 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 manufacturers similarly make it a point to specify if their optic lenses are covered 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 Finishing
Water on a lens does not help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finish.
Optic Installing Choices
Mounting solutions for scopes come in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use throw levers which allow rifle shooters to quickly mount and dismount the optics.
Hex Key Rifle Glass Rings
Normal, 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope install is wonderful for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar design mount, several scopes can often be swapped on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts come in handy for shooting platforms which are transferred between vehicles a lot, to take off the optic from the rifle for protection, or for optics which are adopted in between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less affected by temperature level changes and pressure differences from the outside environment which might possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
