What You Need to Know About Rifle Scopes
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be dialed in to account for various ecological things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have about 11 parts which are found within and on the exterior of the optic. These parts consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. Learn about the eleven parts of rifle scopes.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair lies in regard to the optic’s magnification. It simply implies the reticle is behind or ahead of the magnification lens of the optic. Selecting the most effective type of rifle scope is based upon what style of hunting or shooting you intend on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who understand their target “hold over” and “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Optic Info
Second focal plane glass (SFP) include the reticle to the rear of the zoom lens. This causes the reticle to stay at the very same size in relation to the level of zoom being used. The final result is that the reticle measurements adapt based on the zoom chosen to shoot over greater ranges since the markings represent distinct increments which can vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of optics work for:
- Long distance types of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who would like a clearer optic sight picture without room used up by the larger sized FFP reticle
Rifle Glass Zoom
The extent of scope magnification you need on your optic depends upon the sort of shooting you desire to do. Practically every style of rifle scope provides some degree of magnification. The amount of magnification a scope gives is identified by the dimension, density, and curvatures of the lens glass within the rifle scope. The magnification of the scope is the “power” of the glass. This implies what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Rifle Glass Info
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not adjust considering that it is a set power scope.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes can be tweaked between magnified levels. The power modification is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power settings and the ranges where they could be successfully used. Highly magnified optics will not be as beneficial as lower powered glass because too much zoom can be a bad thing. The same concept relates to extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle.
Info on Rifle Scope Lens Coverings
All top of the line rifle glass lenses are layered. Lens coating is a significant aspect of a rifle system when purchasing high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishes which use different techniques, polarizations, chemicals, and aspects to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating for Optics
Different optic lenses can also have different finishes used to them. All lenses typically have at least some type of treatment or covering used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Covering
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Rifle Optic Mounting Options
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use double individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This type of scope mount is good for rifles which are in need of a durable, rock solid mount which will not move despite just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a faithful scope system on a far away scouting or tournament long gun that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to stop the hex screws from wiggling out after they are installed securely in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles.
Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the optic is less influenced by temperature level 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 good rifle scope to seek out.
