Scope Info
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by making use of a series of lenses within the scope. The scope’s positioning can be dialed in to account for varied environmental aspects like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have around eleven parts which are located inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, windage turrets, focus rings, and other components. Learn about the eleven parts of glass.
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 optic depends on what type of shooting you plan on doing.
First Focal Plane Scope Details
First focal plane optics (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the very same scale in relation to the quantity of zoom being used. The result is that the reticle measurements adjust based on the zoom chosen to shoot over longer ranges considering that the reticle measurements present different increments which can vary with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These particular sorts of scopes work for:
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who choose a clearer optic picture without room taken up by the larger size FFP reticle
Rifle Optic Magnification
The quantity of zoom a scope provides is identified by the diameter, density, 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 Optic Facts
A single power rifle optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change given that it is a set power scope.
About Variable Power Lens Scopes
Variable power rifle scopes can be modified between magnified settings. The power adjustment is handled using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Range Correlation
Here are some suggested scope power settings and the distances where they may be effectively used. Highly magnified rifle scope glass will not be as useful as lower powered glass given that too much zoom can be a negative aspect depending on your shooting distance. The same concept applies to extended distances where the shooter needs to have increased power to see precisely where to properly aim the rifle.
About Lens Finish
All modern rifle optic and scope lenses are layered. There are different types and qualities of glass lens finishings. When researching high end rifle optics and scope setups, Lens coating can be an essential component of defining the capability of the rifle. The glass lenses are one of the most significant pieces of the scope because they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses protects the lens exterior and improves anti glare from refracted sunlight and color profiles.
ED Versus HD Optics
Some scope manufacturers also use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and elements to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Scopes
Different scope lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a finishing put on it so that the lens will be optimally functional in numerous types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can indicate that a company is taking several steps to combat various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not always indicate the multi-coated lens will perform better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle glass.
Anti-water Lens Finishes
Water on a lens doesn’t assist with maintaining a clear sight picture through an optic at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Rifle Scope Installing Options
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically come in quick release versions which use manual levers which enable rifle shooters to rapidly install and dismount the scope.
Hex Key Optic Rings
Standard, clamp style mounting optic rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use double detached rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This type of scope mount is great for rifles which need to have a resilient, rock solid mount which will not change regardless of just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a faithful scope system on a long distance scouting or sniper competition firearm which will hardly ever need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screws from wiggling out after they are mounted tightly in position. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifles which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Rifle Optic Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less altered by temperature changes and pressure variations from the external environment which might possibly enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
