Rifle Scope Details
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom by making use of a set of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of varied environmental considerations like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have about 11 parts which are found within and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the finest type of rifle optic is based around what type of shooting you plan on doing.
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 types of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who understand their target “hold over” as well as “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This induces the reticle to stay at the same dimensions relative to the quantity of magnification being used. The outcome is that the reticle measurements evolve based upon the zoom used to shoot over lengthier distances due to the fact that the markings represent different increments which can vary with the zoom. 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 measurement. These sorts of scopes are beneficial for:
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who select a clearer optic picture with less area used up by the bigger FFP reticle
About Glass Zoom
The extent of scope zoom you need on your optic depends upon the type of shooting you choose to do. Pretty much every type of rifle scope supplies some level of magnification. The level of zoom a scope offers is identified by the diameter, density, and curvatures of the lens glass within the rifle optic. The magnification of the optic is the “power” of the glass. This implies what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.
Fixed Power Lens Optics
A single power rifle optic or scope comes with a zoom 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 kind of scope can not adjust since it is a set power scope.
Adjustable Power Lens Rifle Optic Details
Variable power rifle scopes can be modified between magnified levels. The power modification is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some recommended scope power levels and the ranges where they can be effectively used. Bear in mind that high power optics and scopes will not be as practical as lower powered optics due to the fact that increased zoom can be a negative thing in certain situations. The same relates to extended ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
About Rifle Scope Lens Coverings
All modern rifle scope and optic lenses are layered. There are various types and qualities of glass lens finishes. Lens finish is a crucial aspect of a rifle when thinking of luxury rifle optics and scope units. The glass lenses are one of the most significant parts of the optic given that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses protects the lens surface and also helps with anti glare capabilities from refracted sunshine and color perception.
About Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different methods, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can likewise have different coverings used to them. All lenses usually have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can establish that a maker is taking numerous actions to combat different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also doesn’t always imply the multi-coated lens is much better than a single layered lens. Being “much better” is dependent on the producer’s lens treatment innovation and the quality of components used in constructing the rifle scope.
Optic Lens Anti-water Coating
Water on an optic’s lens doesn’t help with maintaining a clear sight picture through an optic at all. Lots of top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Rifle Optic Mounting Alternatives
Mounting approaches for scopes are available in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use toss levers which allow rifle shooters to quickly install and dismount the glass.
Hex Key Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use a pair of detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This kind of scope mount is ideal for rifles which are in need of a long lasting, rock solid mount which will not shift despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a specialized optics system on a long distance scouting or tournament firearm that will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to stop the hex screw threads from backing out after they are installed safely in place. An example of these rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can also be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining the original sighting settings. These kinds of mounts are useful and convenient for rifles which are carried a lot, to take off the glass from the rifle for protection, or for aiming systems which are adopted between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle optic can wreck a day of shooting and your costly optic by resulting in fogging and generating residue inside of the scope’s tube. A lot of scopes prevent humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Normally, these water resistant optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are concerned about the scope still functioning if it goes overboard and you can still salvage the firearm.
Info on Glass Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less impacted by temp shifts and pressure distinctions from the external environment which might possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
