What You Need to Know About Scopes
Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be dialed in to take into account numerous ecological things like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have around 11 parts which are arranged within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets or 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 type of focal plane an optic has determines where the reticle or crosshair lies relative to the optic’s zoom. It actually means the reticle is located behind or in front of the magnification lens of the scope. Looking for the most suitable style of rifle optic depends on what style of shooting or hunting you plan on undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who know their aim point “hold over” as well as “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without room used up by the bigger FFP reticle
Zoom for Rifle Glass
The amount of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Details
A single power rifle optic and scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is fixed.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a configuration like 2-10×32. These numbers imply the magnification of the scope can be changed between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power manipulation is achieved using the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Glass Power and Ranges
Here are some advised scope power settings and the distances where they can be successfully used. Bear in mind that higher magnification glass will not be as effective as lower magnification level scopes since too much zoom can be a detractor. The very same idea applies to longer ranges where the shooter needs increased power to see exactly where to best aim the rifle.
Rifle Scope Lens Finishing
All state-of-the-art rifle scope lenses are layered. Lens coating is a vital aspect of a rifle’s setup when purchasing high end rifle optics and scope setups.
ED Versus HD Optics
Some rifle scope suppliers will also use “HD” or high-def lense coverings which make the most of different procedures, polarizations, elements, and chemicals to enhance a wide range of colors and viewable target visibility through lenses. This high-def coating is commonly used with more costly, high density lens glass which decreases light’s chance to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often visible around items with well defined shapes as light hits the item from various angles.
Rifle Optic Lens Single Coating Versus Multi-Coating
Various optic lenses can even have different coatings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope designer and how much money you spent on it. The scope’s maker and cost are indications of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Optic Lens Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Mounting Glass on Long Guns
Installing solutions for scopes come in a few options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release versions which use toss levers which permit rifle shooters to rapidly install and dismount the scopes.
Hex Key Glass Rings
Standard, clamp-on style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use a pair of separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This form of scope mount is good for rifle systems which are in need of a durable, hard use mount which will not move no matter how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a faithful scope system on a far away scouting or interdiction rifle which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used to keep the hex screw threads from wiggling out after they are installed tightly 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 Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
About Scope Tube Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less affected by climate alterations and pressure differences from the outside environment which might possibly enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
