What You Need to Know About Rifle Glass
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a range. They do this through magnification by using a set of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of many environmental elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around 11 parts which are found within and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has determines where the reticle or crosshair is located relative to the optic’s zoom. It literally implies the reticle is situated behind or ahead of the magnifying lens of the optic. Looking for the most suitable sort of rifle glass depends on what variety of shooting you plan on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who know their target “hold over” and “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and requires more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who select a clearer optic picture without area taken up by the enlarged FFP reticle
Magnification for Rifle Glass
The amount of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Optics
A single power rifle scope or optic uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change given that it is set from the factory.
Variable Power Lens Scope Info
Variable power rifle scopes can be adjusted between magnification increments. It will note the zoom degree in a format such as 2-10×32. These numbers indicate the magnification of the scope could be set between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adjustment is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some advised scope powers and the distances where they may be successfully used. Bear in mind that high magnification scopes and optics will not be as effective as lower magnification level glass because excessive zoom can be a negative thing in certain situations. The very same idea goes for extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
Details on Lens Coating
All modern-day rifle scope and optic lenses are covered in special coatings. There are different types and qualities of lens coverings. Lens covering is an important element of a rifle when considering luxury rifle optics and targeting systems. The glass lenses are among the most vital parts of the glass given that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses safeguards the lens surface and even improves anti glare from refracted sunlight and color discernibility.
ED Versus HD Optics
Some scope producers likewise use “HD” or high-definition lens finishings which use various procedures, elements, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating for Optics
Different optic lenses can likewise have various coverings applied to them. All lenses normally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing 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 manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a producer is taking numerous steps to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally doesn’t always indicate the multi-coated lens is better than a single layered lens. Being “better” depends on the maker’s lens treatment innovation and the quality of glass used in creating the rifle optic.
Rifle Optic Lens Anti-water Covering
Water on an optical lens does not assist with preserving a clear sight picture through an optic at all. Numerous top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Options for Mounting Rifle Scopes on Firearms
Installing solutions for scopes come in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use toss levers which allow rifle shooters to rapidly install and dismount the scopes.
Hex Key Rifle Scope Ring Mounts
Basic, clamp design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This type of scope mount is excellent for rifles which need to have a resilient, rock solid mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized optics system on a reach out and touch someone hunting or hard target interdiction firearm that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used to protect against the hex screw threads from backing out after they are mounted securely in position. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 back on the rifle while keeping accuracy. These types of mounts come in beneficial for rifles which are moved a lot, to remove the scope glass from the rifle for protection, or for scopes which are chosen for use between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day on the range and your costly optic by triggering fogging and developing residue within the scope’s tube. Many scopes protect against humidity from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these scopes can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the optic still functioning if it falls overboard and you can still salvage the firearm.
Gas Purged Scope Tubes
Another component of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the optic is less affected by condition shifts and pressure distinctions from the outside environment which may possibly permit water vapor to seep 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.
