Rifle Optic Information
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous ecological things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. Many modern rifle optics have around eleven parts which are arranged inside and outside of the scope. These scope parts include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other components. See all eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the perfect type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who prefer a clearer optic sight picture with less space taken up by the larger size FFP reticle
Zoom for Rifle Glass
The quantity of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Scopes
A single power rifle scope will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change because it is set from the factory.
Info About Variable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power modification is achieved by the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power Level and Range Correlation
Here are some suggested scope powers and the ranges where they can be efficiently used. Bear in mind that high power glass will not be as effective as lower magnification level scopes because too much zoom can be a negative thing in certain situations. The exact same idea relates to longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle.
Info on Rifle Glass Lens Coatings
All present day rifle scope lenses are covered. Lens finish can be an essential aspect of a rifle system when buying high end rifle optics and scope setups.
ED Versus HD Rifle Glass
Some scope brands also use “HD” or high-definition lens coatings which use different methods, polarizations, elements, and chemicals to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Glass
Various optic lenses can even have various finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a covering put on it so that it will be optimally functional in numerous types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering 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 manufacturer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Scope Lens Coating
Water on an optic’s lens does not help with preserving a clear sight picture through a scope whatsoever. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Optic Installing Alternatives
Installing solutions for scopes are available in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use manual levers which enable rifle operators to rapidly install and dismount the scopes.
Hex Key Optic Ring Mounts
Basic, clamp type mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is very good for rifle systems which require a durable, rock solid mount which will not shift no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a devoted optics setup on a far away scouting or sniper competition firearm which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used to keep the hex screws from wiggling out after they are mounted securely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly 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 precision. These types of mounts are useful and handy for shooting platforms which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for sight systems which are utilized in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can spoil a day of shooting and your highly-priced optic by inducing fogging and producing residue inside of the scope tube. A lot of scopes protect against humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the scope still functioning if it falls overboard and you can still rescue the rifle.
What to Know About Rifle Scope Tube Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less affected by temperature shifts and pressure differences from the outdoor environment which might potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
