About Rifle Optics
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of varied environmental factors like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes and optics have around 11 parts which are found internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the best type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Optics
First focal plane optics (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who recognize their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle behind the zoom lens. This triggers the reticle to remain at the exact same size in connection with the quantity of zoom being used. The effect is that the reticle measurements evolve based upon the magnification used to shoot over greater ranges considering the reticle markings present distinct increments which vary with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of scopes are beneficial for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and spaces
- Shooters who like a clearer optic picture with less room used up by the enlarged FFP reticle
Rifle Optic Magnification
The quantity of magnification a scope offers is identified by the size, 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 Optics
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change since it is a fixed power scope.
Variable Power Lens Glass Info
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some recommended scope powers and the ranges where they can be effectively used. High power rifle scope glass will not be as effective as lower powered rifle scope glass since too much magnification can be a negative aspect depending on your shooting distance. The same applies to extended distances where the shooter needs sufficient power to see where to best aim the rifle at the target.
About Lens Coverings
All state-of-the-art rifle scope lenses are covered. Lens covering can be a crucial aspect of a rifle’s setup when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coverings which use different techniques, chemicals, polarizations, and aspects to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can likewise have different finishings applied to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope manufacturer and how much money you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Optic Lens Hydrophobic Covering
Water on an optical lens does not improve preserving a clear sight picture through a scope in any way. Numerous top of the line or premium scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Scope Installing Choices
Installing approaches for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release versions which use manual levers which allow rifle operators to rapidly install and dismount the optics.
Hex Key Glass Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope mount is perfect for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can often be swapped in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten tightly 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 retaining precision. These kinds of mounts are useful and beneficial for rifles which are moved 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 from Vortex Optics. It generally costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Glass Tubes
Another part of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less affected by condition shifts and pressure variations from the outdoor environment which may possibly enable 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 look for.
