Scope Facts
Rifle scopes permit you to specifically aim a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adapted for consideration of varied natural factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have about 11 parts which are located internally and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair lies in relation to the optic’s zoom. It actually means the reticle is located behind or before the magnifying lens of the optic. Picking the most reliable sort of rifle optic is dependent on what kind of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the magnifying lens. This induces the reticle to remain at the same scale relative to the level of magnification being used. The outcome is that the reticle measurements evolve based upon the magnification applied to shoot over lengthier distances considering the reticle markings present various increments which change with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These types of optics work for:
- Long distance styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who select a clearer optic picture with less room used up by the larger sized FFP reticle
Rifle Optic Magnification
The quantity of zoom a scope provides is determined 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.
Single Power Lens Optics
A single power rifle scope comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change since it is a fixed power scope.
Info About Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Range Correlation
Here are some recommended scope power levels and the distances where they could be effectively used. High power glass will not be as beneficial as lower magnification optics because too much magnification can be a negative aspect depending on your shooting distance. The same goes for longer ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Details on Lens Finish
All state-of-the-art rifle optic lenses are coated. Lens finishing can be an important element of a rifle when thinking about high end rifle optics and scope systems.
HD Versus ED Rifle Optic Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coatings which use different procedures, polarizations, components, and chemicals to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Rifle Glass Lens Finish Versus Multi-Coating
Different scope lenses can even have various coverings applied to them. All lenses usually have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It needs to have a finish put on it so that the lens will be optimally usable in numerous types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can protect 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 maker and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can prove that a maker is taking several steps to fight different natural factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally doesn’t necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the manufacturer’s lens treatment innovation and the quality of components used in creating the rifle optic.
Info on Hydrophobic Covering
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Glass Installing Options
Installing solutions for scopes are available 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 usually can be found in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the scopes.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use double individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This type of scope mount is effective for rifle systems which require a durable, rock solid mount which will not change no matter just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a dedicated scope system on a far away hunting or tournament firearm that will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used to prevent the hex screws from backing out after they are installed firmly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. A lot of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Info on Optic Tube Gas Purging
Another component of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less influenced by temperature alterations and pressure differences from the outdoor environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
