Optic Info
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by making use of a set of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of different natural factors like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have about 11 parts which are located internally and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle scope depends on what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are small
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the magnification lens. This triggers the reticle to remain at the same scale in connection with the quantity of magnification being used. The outcome is that the reticle measurements shift based on the zoom chosen to shoot over greater ranges given that the markings represent distinct increments which can vary with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular sorts of glass work for:
- Far away kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who like a clearer optic picture without space taken up by the bigger FFP reticle
Magnification for Rifle Scopes
The quantity of scope zoom you need on your scope depends on the type of shooting you plan to do. Almost every style of rifle glass provides some level of magnification. The amount of zoom a scope delivers is established by the dimension, density, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the glass. This denotes what the shooter is observing through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Info About Fixed Single Power Lens Rifle Glass
A single power rifle optic uses a zoom number designator like 4×32. This suggests 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 given that it is a fixed power optic.
Info on Variable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification level in a configuration such as 2-10×32. These numbers suggest the magnification of the scope can be adjusted in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power manipulation is accomplished by applying the power ring component of the scope near the rear of the scope by the eye bell piece.
Scope Power and Ranges
Here are some recommended scope power levels and the distances where they may be efficiently used. High power glass will not be as effective as lower powered optics given that too much zoom can be a negative aspect depending on your shooting distance. The very same idea goes for extended ranges where the shooter needs increased power to see exactly where to properly aim the rifle.
Optic Lens Finishing
All modern-day rifle scope lenses are covered. Lens finish is a crucial aspect of a rifle when looking into high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope makers even use “HD” or high-def glass finishings that make the most of different procedures, components, chemical substances, and polarizations to extract a wide range of colors and viewable target definition through lenses. This high-def coating is frequently used with increased density glass which lowers light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be visible around items with defined shapes as light hits the item from particular angles.
Single Finishing Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a coating put on it so that the lens will be efficiently functional in many kinds of environments, degrees of light (full light VS shade), 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 coated lens depends on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Coating for Optics
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Scope Mounting Alternatives
Mounting solutions for scopes come 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 various kinds of mounts also usually come in quick release variations which use throw levers which permit rifle shooters to quickly mount and remove the scopes.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This kind of scope mount is exceptional for rifle systems which are in need of a long lasting, hard use mount which will not move no matter just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you want for a devoted scope setup on a reach out and touch someone hunting or competition firearm which will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from wiggling out after they are installed tightly in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used between numerous rifles.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day on the range and your pricey optic by resulting in fogging and developing residue inside of the scope’s tube. A lot of optics protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Generally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are worried about the scope still functioning if it is submerged in water and you can still retrieve the firearm.
Rifle Optic Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less altered by temperature alterations and pressure differences from the outside environment which might possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
