What You Need to Know About Scopes
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adjusted to take into account numerous natural aspects like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Many modern rifle scopes have about 11 parts which are found inside and outside of the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle scope is based around what type of shooting you plan on doing.
Info About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are low
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This induces the reticle to stay at the same overall size relative to the level of zoom being used. The result is that the reticle measurements change based on the magnification chosen to shoot over lengthier distances due to the fact that the reticle markings present various increments which vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular sorts of scopes work for:
- Far away kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who would like a clearer optic sight picture with less space used up by the enlarged FFP reticle
About Optic Zoom
The amount of zoom 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.
Fixed Single Power Lens Scopes
A single power rifle optic or scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power optic.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power adjustment is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some recommended scope powers and the ranges where they could be effectively used. Remember that high magnification glass will not be as practical as lower powered scope and optics due to the fact that increased magnification can be a bad thing. The very same idea goes for extended ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Rifle Optic Lens Finish
All modern-day rifle optic lenses are coated. Lens coating can be a significant element of a rifle’s setup when considering high end rifle optics and scope systems.
HD Versus ED Glass Lens Coatings
Some scope makers also use “HD” or high-definition lens finishings which use different processes, components, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering 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 designer and how much money you spent for it. Both are signs of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has multiple treatments applied to the surfaces. If a lens receives multiple treatments, it can establish that a producer is taking several steps to combat different natural factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally does not necessarily indicate the multi-coated lens is better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle optic.
Hydrophobic Finishing for Optics
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Options for Installing Scopes on Firearms
Mounting approaches for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use manual levers which permit rifle operators to rapidly install and remove the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp-on design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use two independent rings to support the scope, and are made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This type of scope mount is great for rifle systems which need to have a resilient, unfailing mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted optics system on a reach out and touch someone scouting or tournament firearm which will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from backing out after they are installed securely in position. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set usually costs around $200 USD
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for rifles which are transported a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Details on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can wreck a day of shooting and your expensive optic by resulting in fogging and producing residue within the scope tube. Many scopes protect against humidity from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are worried about the optic still functioning if it goes overboard and you can still find the rifle.
Gas Purged Rifle Glass Tubes
Another part of preventing 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 taken up by the gas, the scope is less influenced by temp shifts and pressure differences from the outside environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
