What You Need to Know About Rifle Scopes
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target at range. They do this through zoom using a set of lenses within the scope. The scope’s positioning can be adapted for consideration of separate ecological factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle optics have about 11 parts which are located within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. See all eleven parts of scopes.
The Styles 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 in relation to the optic’s magnification. It actually indicates the reticle is located behind or before the magnifying lens of the scope. Picking the very best style of rifle glass depends on what kind of shooting you intend on undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the amount 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 distance. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who understand their aim point “hold over” and “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who want a clearer optic sight picture with less space taken up by the enlarged FFP reticle
Zoom for Scopes
The amount of zoom a scope offers is identified 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.
About Fixed Single Power Lens Rifle Optics
A single power rifle scope or optic comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate given that it is a fixed power scope.
Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the magnification degree in a format such as 2-10×32. These numbers suggest the zoom of the scope could be changed in between 2x and 10x power. This also involves the powers in-between 2 and 10. The power manipulation is achieved by operating the power ring part of the scope near the rear of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some suggested scope power levels and the ranges where they can be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification rifle scope glass considering that too much magnification can be a negative aspect depending on your shooting distance. The same relates to extended distances where the shooter needs adequate power to see where to best aim the rifle.
Optic Lens Coating
All state-of-the-art rifle optic lenses are layered. Lens coating is an essential element of a rifle’s setup when thinking about high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use various procedures, chemicals, polarizations, and elements to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Optic Lens Finishing Versus Multi-Coating
Various scope lenses can even have different coatings applied to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in many types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Details on Anti-water Finishing
Water on a scope lens doesn’t help with maintaining a clear sight picture through an optic at all. Many top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Scope Mounting Alternatives
Installing approaches for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release variations which use throw levers which allow rifle shooters to quickly install and remove the glass.
Scope Mounts with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use double independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This kind of scope mount is ideal for rifle systems which are in need of a resilient, unfailing mount which will not shift regardless of how much the scope is moved or jarring the rifle takes. These are the style of mounts you want for a dedicated scope system on a reach out and touch someone hunting or competition long gun that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screws from wiggling out after they are installed firmly in position. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
What to Know About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less impacted by climate alterations and pressure differences from the outdoor environment which may possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
