About Scopes
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification using a set of lenses within the scope. The scope’s positioning can be dialed in to account for numerous environmental elements like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around eleven parts which are located within and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies relative to the scopes magnification. It actually indicates the reticle is located behind or ahead of the magnifying lens of the scope. Considering the most suitable form of rifle glass depends upon what style of shooting or hunting you anticipate doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their long gun
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Scope Details
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This induces the reticle to stay at the same overall size relative to the volume of zoom being used. The result is that the reticle measurements evolve based upon the zoom chosen to shoot over greater ranges due to the fact that the reticle markings present distinct increments which can vary with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These varieties of glass work for:
- Far away types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture without room taken up by the larger sized FFP reticle
Rifle Scope Zoom
The level of scope zoom you need on your scope is based on the style of shooting you would like to do. Practically every kind of rifle optic supplies some amount of zoom. The level of zoom a scope delivers is established by the size, thickness, and curves of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the opic. This indicates what the shooter is observing through the scope is amplified times the power element of what can normally be seen by human eyes.
Single Power Lens Rifle Glass Info
A single power rifle scope uses 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 zoom of this kind of scope can not fluctuate since it is set from the factory.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes use variable power levels. The power adjustment is handled using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope power settings and the distances where they can be efficiently used. Remember that higher magnification scopes and optics will not be as effective as lower magnification level optics and scopes due to the fact that excessive zoom can be a detractor. The same idea goes for extended ranges where the shooter needs to have adequate power to see where to best aim the rifle.
Info on Lens Coating
All contemporary rifle optic and scope lenses are layered. Lens finish is a crucial aspect of a shooting platform when looking at high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens finishes which use different procedures, chemicals, polarizations, and elements to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can also have different finishes used to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has multiple treatments applied to them. If a lens receives multiple treatments, it can indicate that a maker is taking several steps to combat various natural factors like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also does not always imply the multi-coated lens is better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment techniques and the quality of components used in developing the rifle optic.
Optic Lens Hydrophobic Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Options for Installing Glass on Long Guns
Installing solutions for scopes are available in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use manual levers which permit rifle operators to rapidly install and dismount the scope.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of independent rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for far away precision shooting. This type of scope mount is very good for rifle systems which need a resilient, unfailing mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a faithful scope system on a reach out and touch someone hunting or competition rifle which will seldom need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to keep the hex screws from backing out after they are installed securely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set normally costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between several rifles.
Info Around Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your highly-priced optic by causing fogging and generating residue inside of the scope tube. The majority of optics prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant. Usually, these optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the optic still working if it goes over the side and you can still rescue the gun.
Glass Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the optic is less altered by temperature level alterations and pressure variations from the external environment which might potentially permit 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 seek out.
