Information About Scopes
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be dialed in to take into account many natural elements like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle optics have around eleven parts which are located internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who have an idea for their target “hold over” as well as “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who would like a clearer optic picture with less space used up by the bigger FFP reticle
Details on Scope Zoom
The level of scope magnification you need on your optic is based on the sort of shooting you wish to do. Nearly every style of rifle optic offers some amount of magnification. The amount of magnification a scope delivers is established by the dimension, thickness, and curves of the lens glass inside of the rifle scope. The zoom of the scope is the “power” of the glass. This suggests what the shooter is aiming at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Single 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 and the objective lens is 32mm. The zoom of this type of optic can not change because it is a fixed power scope.
About Variable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Range Correlation
Here are some advised scope power settings and the ranges where they can be successfully used. Highly magnified rifle scope glass will not be as useful as lower magnification scopes given that too much magnification can be a negative aspect depending on your shooting distance. The same idea goes for longer ranges where the shooter needs sufficient power to see where to best aim the rifle.
About Scope Lens Covering
All contemporary rifle scope lenses are layered. Lens finishing is a significant aspect of a shooting platform when buying high end rifle optics and scope equipment.
Info on Lens Coatings – HD Versus ED
Some scope suppliers also use “HD” or high-definition glass coverings which use various procedures, aspects, chemicals, and polarizations to enhance various color ranges and viewable target visibility through lenses. This high-def finishing is often used with more costly, high density lens glass which reduces light’s opportunity to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be obvious around items with hard edges and outlines as light hits the item from certain angles.
Info on Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishings used to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope maker and how much money you paid 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 covered or “multi” covered. This means the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can indicate that a maker is taking multiple actions to fight various environmental factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also does not always mean the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the producer’s lens treatment innovation and the quality of glass used in constructing the rifle optic.
Rifle Optic Lens Anti-water Finishing
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic covering which is water repellent.
Options for Installing Rifle Optics on Long Guns
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use toss levers which allow rifle operators to quickly install and remove the glass.
Rifle Scope Mounting Solutions with Hex Key Rings
Normal, clamp design 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope mount is fine for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a similar style mount, several scopes can also be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top style Picatinny rail. This permits 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 shooting platforms which are moved a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are adopted between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another element of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less impacted by temp changes and pressure variations from the external environment which might possibly allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
