Rifle Glass Facts
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses inside the scope. The scope’s alignment can be adapted to take into account different environmental considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. Many modern rifle scopes have about eleven parts which are arranged internally and outside of the scope. These parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the perfect type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optic Details
First focal plane glass (FFP) feature the reticle before the magnifying lens. This triggers the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to remain at the same scale in relation to the quantity of magnification being used. The result is that the reticle dimensions change based upon the magnification applied to shoot over lengthier distances since the reticle measurements represent distinct increments which fluctuate with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of glass work for:
- Long distance kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who desire a clearer optic picture without room taken up by the bigger FFP reticle
Glass Magnification
The quantity of magnification a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Single Power Lens Optics
A single power rifle optic and scope will have a magnification 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 kind of optic can not change considering that it is a fixed power optic.
Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power change is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Ranges
Here are some suggested scope powers and the ranges where they may be effectively used. Highly magnified scopes will not be as useful as lower magnification rifle scope glass due to the fact that too much zoom can be a bad thing. The exact same idea applies to extended distances where the shooter needs adequate power to see precisely where to properly aim the rifle.
Lens Coating for Rifle Glass
All present day rifle scope and optic lenses are layered. Lens coating can be an important element of a rifle’s setup when looking at high end rifle optics and scope systems.
About Optic Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens finishes which use different procedures, components, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Optic Lens Finishing Versus Multi-Coating
Different scope lenses can even have different finishes applied to them. All lenses normally have at least some kind of treatment or finish applied to them before they are used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It must have a coating applied to it so that the lens will be optimally functional in many kinds of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can offer protection to 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 covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Rifle Glass Lens Hydrophobic Finish
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 high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Optic Installing Options
Installing options for scopes come in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release variations which use toss levers which enable rifle shooters to quickly mount and dismount the optics.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use double independent rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This type of scope mount is good for rifle systems which are in need of a long lasting, unfailing mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you should have for a dedicated optics setup on a far away scouting or competitors rifle which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from wiggling out after they are installed safely in position. An example of these rings are the 30mm style made by the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be switched out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving precision. These types of mounts come in convenient for rifles which are transferred a lot, to take off the glass from the rifle for protection, or for aiming systems which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your costly optic by causing fogging and making residue inside of the scope tube. The majority of scopes prevent humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Normally, these optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for common use rifles, unless you plan on taking your rifle aboard a watercraft and are concerned about the scope still functioning if it goes overboard and you can still retrieve the firearm.
Optic Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less influenced by temperature shifts and pressure variations from the external environment which might potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
