What You Need to Know About Rifle Scopes
Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through zoom using a set of lenses within the scope. The scope’s positioning can be adapted to account for different environmental aspects like wind and elevation increases 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 with the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have around 11 parts which are located internally and externally on the optic. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the finest 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 zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who recognize their target “hold over” and also “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This causes the reticle to remain at the exact same scale relative to the amount of zoom being used. The result is that the reticle measurements alter based upon the magnification applied to shoot over longer ranges considering the reticle measurements present distinct increments which fluctuate with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These kinds of optics work for:
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who prefer a clearer optic picture without space taken up by the larger sized FFP reticle
Rifle Scope 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.
Info on Single Power Lens Glass
A single power rifle optic will have 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 type of scope can not adjust given that it is a fixed power scope.
Variable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification increments. 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 also involves the power levels in-between 2 and 10. The power shift is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope power levels and the ranges where they may be successfully used. Keep in mind that high power scopes will not be as practical as lower magnification level scope and optics because too much magnification can be a negative thing in certain situations. The same idea goes for extended ranges where the shooter needs enough power to see exactly where to properly aim the rifle.
About Lens Coverings
All modern rifle optic lenses are layered. There are various types and qualities of finishings. Lens finish is an important aspect of a rifle when thinking about luxury rifle optics and targeting systems. The glass lenses are among the most important components of the scope due to the fact that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses safeguards the lens exterior and also assists with anti glare capabilities from excess direct sunlight and color profiles.
HD Versus ED Lenses
Some scope makers likewise use “HD” or high-definition lens finishes which use various techniques, polarizations, aspects, and chemicals 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 Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can also have various coatings used to them. All lenses usually have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically 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 scope. The quality of a single layered lens depends on the scope developer and the amount you spent on it. Both the make and cost are signs of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has numerous treatments applied to them. If a lens receives numerous treatments, it can prove that a producer is taking multiple actions to combat various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally does not necessarily indicate the multi-coated lens is much better than a single covered lens. Being “much better” depends upon the producer’s lens treatment solutions and the quality of glass used in constructing the rifle glass.
Hydrophobic Lens Coating
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic coating.
Rifle Optic Installing Choices
Installing options for scopes can be found in a few choices. There are the standard scope rings which are separately installed 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 toss levers which enable rifle shooters to rapidly mount and remove the optics.
Hex Key Glass Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts come in beneficial for rifles which are transported a lot, to take off the scope glass from the rifle for protection, or for optics which are utilized between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your expensive optic by triggering fogging and generating residue within the scope’s tube. Many optics prevent humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water resistant optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity avoidance for standard use rifles, unless you anticipate taking your rifle on boats and are worried about the scope still working if it goes overboard and you can still find the firearm.
Rifle Optic Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less influenced by climate shifts and pressure distinctions from the external environment which could potentially permit 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 seek out.
