Glass Info
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by utilizing a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of various natural elements like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have around eleven parts which are arranged inside and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. See all eleven parts of a scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. This triggers the reticle to remain at the exact same scale in connection with the volume of zoom being used. The outcome is that the reticle measurements adjust based upon the magnification employed to shoot over lengthier ranges given that the markings present various increments which can vary with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular types of glass are handy for:
- Far away styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who choose a clearer optic sight picture with less area used up by the larger sized FFP reticle
Rifle Glass Zoom
The quantity of zoom a scope supplies is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Optics
A single power rifle scope or optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change because it is set from the factory.
Variable Power Lens Scope Details
Variable power rifle scopes have adjustable power. It will list the magnification amount in a format such as 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always includes the powers in-between 2 and 10. The power modification is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some advised scope power levels and the ranges where they could be successfully used. Consider that higher magnification scopes and optics will not be as effective as lower magnification level scope and optics because increased magnification can be a negative thing in certain situations. The exact same concept applies to longer distances where the shooter needs enough power to see precisely where to best aim the rifle.
Lens Covering for Rifle Glass
All modern-day rifle scope lenses are coated. There are different types and qualities of lens finishes. Lens finish is an essential element of a rifle’s setup when considering high-end rifle optics and scope equipment. The lenses are one of the most essential pieces of the optic given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens surface area and also helps with anti glare from excess sunlight and color perception.
About Scope Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use various processes, aspects, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating for Optics
Different optic lenses can also have various finishings applied to them. All lenses usually have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
This lens treatment can protect 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 coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Finish for Rifle Glass
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Installing Glass on Firearms
Installing options 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 scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use toss levers which allow rifle shooters to rapidly install and remove the glass.
Hex Key Rifle Scope Ring Mounting Solutions
Basic, clamp type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are made 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 shift no matter just how much the scope is moved or abuse the rifle takes. These are the style of mounts you really want to have for a faithful optics setup on a reach out and touch someone scouting or sniper competition firearm that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screws from backing out after they are mounted safely in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, a number of scopes can often be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining the original sighting settings. These kinds of mounts are useful and handy for shooting platforms which are carried a lot, to take off the glass from the rifle for protection, or for scopes which are chosen for use in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle optic can spoil a day on the range and your pricey optic by triggering fogging and generating residue within the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof. Generally, these scopes can be submerged under 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 conventional use rifles, unless you intend on taking your rifle sailing and are concerned about the scope still working if it falls overboard and you can still recover the rifle.
Glass Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the optic is less impacted by climate changes and pressure variations from the external environment which might possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
