What You Need to Know About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target over a range. They do this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adapted to account for many environmental elements like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have about 11 parts which are arranged inside and outside of the optic. These parts include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. See all eleven parts of scopes.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has identifies where the reticle or crosshair lies in relation to the optic’s zoom. It simply implies the reticle is behind or ahead of the magnification lens of the scope. Deciding on the most ideal style of rifle glass is based on what variety of shooting you intend on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and uses up 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 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.
- Far away types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who like a clearer optic sight picture with less space used up by the larger size FFP reticle
Zoom for Rifle Glass
The quantity of zoom a scope supplies is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scopes
A single power rifle optic and scope comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change because it is a fixed power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification power levels. It will list the magnification amount in a configuration such as 2-10×32. These numbers indicate the zoom of the scope could be changed between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power shift is achieved utilizing 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 advised scope power settings and the ranges where they can be successfully used. High power scopes will not be as useful as lower powered glass given that too much magnification can be a bad thing. The same goes for longer ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle at the target.
Rifle Optic Lens Finish
All state-of-the-art rifle scope lenses are coated. Lens finish can be a crucial element of a shooting system when looking into high end rifle optics and scope equipment.
HD Versus ED Lenses
Some optic manufacturers additionally use “HD” or high-def lens coatings which use different processes, polarizations, components, and chemicals to extract various color ranges and viewable definition through the lens. This HD finishing is normally used with more costly high density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around items with hard edges and shapes as light hits the object from certain angles.
Rifle Glass Lens Single Coating Versus Multi-Coating
Different optic lenses can likewise have various coverings used to them. All lenses generally have at least some type of treatment or coating used 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 preserve the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope producer and how much money you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Lens Coating
Water on a scope’s lens doesn’t support maintaining a clear sight picture through an optic in any way. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface area of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Rifle Scope Installing Options
Mounting solutions for scopes are available in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use toss levers which allow rifle operators to quickly mount and remove the scope.
Hex Key Rifle Optic Rings
Basic, clamp-on design mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use two independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This type of scope mount is great for rifles which require a resilient, rock solid mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a faithful scope system on a far away scouting or competitors firearm that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to prevent the hex screw threads from wiggling out after they are installed firmly in place. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible style mount. These types of mounts are handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Glass Tubes
Another component of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the glass is less altered by condition changes and pressure differences from the outside environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
