Information Rifle Scopes
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account separate natural aspects like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle optics have about eleven parts which are arranged internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials, focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Glass
First focal plane glass (FFP) include the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who want a clearer optic sight picture with less area used up by the larger sized FFP reticle
Ins and Outs of Scope Magnification
The extent of scope magnification you need on your glass is based on the type of shooting you like to do. Almost every kind of rifle glass supplies some amount of magnification. The quantity of zoom a scope provides is identified by the size, thickness, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This denotes what the shooter is aiming at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
About Single Power Lens Rifle Scopes
A single power rifle optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change since it is a fixed power optic.
Variable Power Lens Scope Facts
Variable power rifle scopes use enhanced power. The power adjustment is performed by using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Scopes
Here are some suggested scope power levels and the distances where they may be effectively used. Keep in mind that high magnification optics and scopes will not be as efficient as lower powered scopes since excessive zoom can be a detractor. The exact same concept goes for extended ranges where the shooter needs sufficient power to see precisely where to best aim the rifle.
About Rifle Glass Lens Finishes
All top teir rifle optic and scope lenses are coated. Lens finishing can be a significant aspect of a rifle when looking at high end rifle optics and scope systems.
ED Versus HD Glass
Some scope makers additionally use “HD” or high-definition lens coatings that take advantage of various procedures, components, polarizations, and chemicals to draw out numerous color ranges and viewable target definition through lenses. This HD finishing is frequently used with more costly, high density glass which lowers light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often obvious around things with well defined shapes as light hits the object from certain angles.
What to Know About Single Finish Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses generally have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope developer and just how much you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to them. If a lens gets several treatments, it can indicate that a producer is taking multiple steps to combat various natural elements like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally does not necessarily imply the multi-coated lens will perform much better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment techniques and the quality of materials used in constructing the rifle optic.
Hydrophobic Optic Lens 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 high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering.
Options for Mounting Scopes on Long Guns
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use toss levers which permit rifle shooters to rapidly mount and remove the glass.
Hex Key Rifle Scope Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope install is excellent for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day on the range and your highly-priced optic by causing fogging and generating residue inside of the scope’s tube. Many optics prevent wetness from entering the scope tube with a series of sealing O-rings which are water resistant. Normally, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness avoidance for conventional use rifles, unless you intend on taking your rifle aboard a watercraft and are concerned about the scope still performing if it goes over the side and you can still retrieve the gun.
Gas Purged Rifle Scope Tubes
Another component of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less affected by condition changes and pressure distinctions from the outdoor environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
