About Rifle Optics
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by making use of a series of lenses within the scope. The scope’s positioning can be adapted to account for separate natural considerations like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have about 11 parts which are located inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other parts. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has establishes where the reticle or crosshair lies in regard to the scopes zoom. It actually means the reticle is behind or in front of the magnification lens of the optic. Looking for the most ideal type of rifle glass is dependent on what type of shooting or hunting you anticipate doing.
Info on First Focal Plane Optics
First focal plane scopes (FFP) include the reticle in front of the magnifying lens. This triggers 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 range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who like a clearer optic picture without room taken up by the larger size FFP reticle
Magnification for Rifle Glass
The quantity of scope zoom you require depends upon the type of shooting you choose to do. Just about every style of rifle optic supplies some amount of zoom. The volume of zoom a scope delivers is determined by the size, density, and curvatures of the lenses within the rifle scope. The magnification level of the scope is the “power” of the scope. This means what the shooter is aiming at through the scope is magnified times the power element of what can usually be seen by human eyes.
About Fixed Single Power Lens Glass
A single power rifle optic or scope comes with a zoom 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 kind of optic can not change considering that it is a fixed power optic.
Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will note the magnification level in a format like 2-10×32. These numbers suggest the magnification of the scope could be set between 2x and 10x power. This also involves the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some suggested scope powers and the ranges where they could be efficiently used. High power rifle scope glass will not be as effective as lower magnification level glass because too much zoom can be a negative aspect depending on your shooting distance. The exact same idea applies to extended ranges where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Details on Scope Lens Finishes
All state-of-the-art rifle optic lenses are covered. Lens finishing is an important element of a shooting system when purchasing high end rifle optics and scope setups.
About Lens Coatings – HD Versus ED
Some glass makers also use “HD” or high-def glass finishings that employ different procedures, aspects, compounds, and polarizations to extract separate color ranges and viewable target definition through lenses. This high-definition finishing is commonly used with greater density glass which lowers light’s chance to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around things with hard edges and shapes as light hits the object from particular angles.
Single Covering Versus Multi-Coating for Scopes
Various optic lenses can also have different coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and boosting 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 optic. The quality of a single layered lens depends upon the scope developer and just how much you spent for it. Both are indications of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Finishing for Glass
Water on an optic’s lens does not help with preserving a clear sight picture through a scope in any way. Many top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface area of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Choices for Installing Glass on Firearms
Mounting solutions for scopes come in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release variations which use throw levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Glass Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount 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 is developed for long range precision shooting. This type of scope mount is wonderful for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These types of mounts are useful and practical for shooting platforms which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for scopes which are employed in between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your highly-priced optic by causing fogging and creating residue inside of the scope tube. Most optics protect against moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Generally, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are concerned about the optic still performing if it falls overboard and you can still salvage the gun.
Gas Purged Optic Tubes
Another component of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less altered by temp shifts and pressure differences from the outdoor environment which may potentially permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
