Information About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom using a set of lenses within the scope. The scope’s alignment can be dialed in to account for numerous ecological elements like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have about eleven parts which are arranged inside and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal 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) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who want a clearer optic sight picture without space taken up by the bigger FFP reticle
About Glass Zoom
The amount of magnification a scope provides is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Scopes
A single power rifle scope will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is a fixed power scope.
Variable Power Lens Rifle Optic Facts
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom level in a format such as 2-10×32. These numbers indicate the zoom of the scope can be adjusted in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adjustment is accomplished by employing the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope power settings and the distances where they could be efficiently used. Bear in mind that higher power scopes will not be as practical as lower magnification level glass because increased zoom can be a negative thing in certain situations. The very same idea goes for longer distances where the shooter needs sufficient power to see where to properly aim the rifle.
Details on Rifle Glass Lens Finishes
All contemporary rifle scope and optic lenses are coated. Lens coating is an important aspect of a rifle when considering high end rifle optics and scope systems.
ED Versus HD Glass
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use various techniques, polarizations, chemicals, and components to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Rifle Scope Lens Coating Versus Multi-Coating
Different optic lenses can even have different finishings applied 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. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a coating applied to it so that the lens will be optimally functional in numerous kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less beneficial 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 makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Scope Lens Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Installing Rifle Scopes on Firearms
Installing approaches for scopes can be found in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use manual levers which permit rifle shooters to quickly install and remove the scopes.
Hex Key Glass Rings
Basic, clamp-on type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use a pair of separate rings to support the optic, and are normally made from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This form of scope mount is exceptional for rifles which are in need of a durable, hard use mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a devoted scope system on a long distance hunting or tournament long gun that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screws from wiggling out after they are mounted safely in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a comparable style mount, a number of scopes can also be switched on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These types of mounts come in handy for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount type is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can spoil a day of shooting and your highly-priced optic by inducing fogging and developing residue within the scope tube. A lot of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, these water resistant optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are concerned about the scope still functioning if it is submerged in water and you can still rescue the gun.
Info Around Scope Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the scope is less impacted by temperature level changes and pressure variations from the outside environment which may 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.
