Rifle scopes allow you to specifically aim a rifle at different targets by aligning your eye with the target over a range. They accomplish this through zoom by employing a series of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate ecological elements like wind and elevation increases or decreases 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 viewing with the scope as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle optics have about 11 parts which are found internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their target “hold over” plus “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who would like a clearer optic picture without space taken up by the larger sized FFP reticle
Details on Optic Magnification
The level of scope magnification you need is based on the kind of shooting you want to do. Just about every kind of rifle glass supplies some degree of magnification. The amount of zoom a scope gives is established by the size, density, and curves of the lenses within the rifle optic. The zoom of the optic is the “power” of the opic. This indicates what the shooter is checking out through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Info About Fixed Power Lens Rifle Glass
A single power rifle optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate given that it is set from the factory.
Adjustable Power Lens Rifle Optic Facts
Variable power rifle scopes use enhanced power. The power change is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Glass
Here are some suggested scope power settings and the ranges where they can be successfully used. High power glass will not be as beneficial as lower magnification level glass given that too much zoom can be a bad thing. The exact same concept goes for extended distances where the shooter needs increased power to see exactly where to best aim the rifle.
Details on Lens Covering
All cutting-edge rifle scope and optic lenses are covered. Lens finish can be an essential aspect of a rifle system when looking into high end rifle optics and scope systems.
ED Versus HD Optics
Some scope makers also use “HD” or high-definition lens finishings which use various procedures, polarizations, chemicals, and elements to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Info on Single Finishing Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finish placed on it so that it will be optimally functional in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope designer and how much you paid for it. Both the make and cost are indicators of the lens quality.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Glass Lens Anti-water Finishing
Water on a lens does not assist with preserving 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 hydrophobic or hydrophilic finish which is water repellent.
Rifle Scope Installation Alternatives
Installing solutions for scopes can be found in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use manual levers which permit rifle operators to rapidly mount and dismount the scopes.
Hex Key Scope Rings
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use a pair of individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This form of scope mount is effective for rifle systems which are in need of a resilient, unfailing mount which will not shift regardless of how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should have for a specialized optics system on a long distance scouting or hard target interdiction rifle which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screw threads from wiggling out after they are installed safely in place. An example of these rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These kinds of mounts come in beneficial for rifles which are shipped a lot, to take off the glass from the rifle for protection, or for sight systems which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by resulting in fogging and creating residue within the scope’s tube. Most scopes prevent wetness from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for common use rifles, unless you intend on taking your rifle on boats and are worried about the scope still working if it goes overboard and you can still find the firearm.
Scope Gas Purging
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 area is already occupied by the gas, the glass is less altered by temp changes and pressure differences from the outside environment which might potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
