Rifle Optic Info
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a set of lenses inside the scope. The scope’s alignment can be adapted to account for separate environmental things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around eleven parts which are arranged within and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the finest type of rifle glass is based on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who would like a clearer optic sight picture with less area used up by the larger sized FFP reticle
About Optic Zoom
The quantity of magnification a scope provides is identified 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 Rifle Glass Details
A single power rifle scope comes with 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 type of optic can not fluctuate since it is a set power scope.
Variable Power Lens Optics
Variable power rifle scopes can be modified between magnified settings. The power change is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some advised scope powers and the distances where they may be effectively used. Remember that high power optics will not be as effective as lower magnification level optics and scopes since increased zoom can be a detractor. The exact same idea goes for longer distances where the shooter needs to have increased power to see where to best aim the rifle at the target.
Lens Covering for Optics
All top teir rifle glass lenses are coated. Lens coating is an essential aspect of a rifle’s setup when considering high end rifle optics and scope setups.
ED Versus HD Glass
Some scope companies will also use “HD” or high-def lense coverings which take advantage of different procedures, chemicals, elements, and polarizations to extract different color ranges and viewable definition through lenses. This high-definition finish is frequently used with increased density glass which decreases light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over items with hard edges and outlines as light hits the object from various angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can even have different finishes applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a coating placed on it so that the lens will be efficiently usable in lots of types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Rifle Scope Lens Anti-water Coating
Water on an optical lens doesn’t improve preserving a clear sight picture through an optic at all. Numerous top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Options for Installing Glass on Long Guns
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release versions which use manual levers which enable rifle operators to quickly mount and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Basic, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This form of scope mount is great for rifle systems which need to have a long lasting, unfailing mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated scope system on a far away hunting or tournament long gun which will hardly ever need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to stop the hex screw threads from backing out after they are installed securely in position. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts come in beneficial for rifles which are moved a lot, to take off the glass from the rifle for protection, or for sight systems which are adopted between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your highly-priced optic by resulting in fogging and developing residue inside of the scope’s tube. Most scopes prevent moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are worried about the optic still performing if it is submerged in water and you can still salvage the firearm.
Rifle Scope Gas Purging
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less altered by condition alterations and pressure distinctions from the outdoor environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
