Rifle Glass Details
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses within the scope. The scope’s positioning can be dialed in to account for many ecological elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes and optics have around eleven parts which are found within and externally on the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other parts. Learn about the eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane a scope has decides where the reticle or crosshair lies in connection with the scopes magnification. It actually implies the reticle is located behind or before the magnification lens of the optic. Picking the most desired kind of rifle scope is dependent on what variety of shooting you anticipate doing.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are low
- Experienced shooters who understand their target “hold over” as well as “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the magnification 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.
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who choose a clearer optic picture with less space used up by the bigger FFP reticle
Ins and Outs of Rifle Scope Zoom
The measure of scope magnification you need is based on the style of shooting you want to do. Almost every style of rifle scope supplies some amount of magnification. The quantity of magnification a scope supplies is determined by the dimension, thickness, and curvatures of the lens glass inside of the rifle scope. The magnification of the scope is the “power” of the scope. This means what the shooter is aiming at through the scope is amplified times the power factor of what can generally be seen by human eyes.
Single Power Lens Rifle Glass Info
A single power rifle scope uses 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 kind of optic can not adjust since it is a fixed power optic.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will list the zoom level in a configuration like 2-10×32. These numbers mean the magnification of the scope could be changed in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adjustment is achieved by working with the power ring part of the scope near the back of the scope by the eye bell piece.
Glass Power Level and Ranges
Here are some recommended scope power settings and the distances where they can be successfully used. High power glass will not be as efficient as lower magnification glass considering that too much zoom can be a bad thing. The same concept goes for longer ranges where the shooter needs to have adequate power to see where to properly aim the rifle.
Info on Lens Finish
All top teir rifle optic lenses are covered. Lens coating can be a vital element of a shooting system when thinking about high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens coverings which use various procedures, chemicals, aspects, and polarizations to draw out a wide range of colors and viewable definition 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 Glass
Various optic lenses can even have various coverings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in many kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope company and how much money you spent paying for it. Both are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” coated. This indicates the lens has had multiple treatments applied to them. If a lens receives multiple treatments, it can prove that a maker is taking numerous actions to fight various environmental factors like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also doesn’t always suggest the multi-coated lens is better than a single coated lens. Being “much better” hinges on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle optic.
Hydrophobic Scope Lens Finishing
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Choices for Mounting Scopes on Firearms
Installing solutions for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release variations which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Rifle Optic Mounts with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are made for far away precision shooting. This kind of scope mount is great for rifle systems which need a resilient, unfailing mount which will not change regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized optics setup on a long distance scouting or competition rifle that will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to protect against the hex screw threads from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Multiple scopes can also be switched out if they all use a similar design mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can destroy a day of shooting and your highly-priced optic by causing fogging and developing residue within the scope’s tube. Most optics protect against wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Generally, these optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough wetness avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still functioning if it is submerged in water and you can still find the gun.
Optic Gas Purging
Another element of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less altered by temperature shifts and pressure distinctions from the outside environment which might potentially enable 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.
