Facts About Rifle Scopes
Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by using a set of lenses within the scope. The scope’s alignment can be dialed in to account for separate environmental factors like wind and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes have around eleven parts which are arranged inside and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. Learn about the eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the optimal type of rifle optic is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are small
- Experienced shooters who understand their aim point “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane glass (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to stay at the same overall size in relation to the volume of zoom being used. The outcome is that the reticle measurements alter based upon the zoom used to shoot over longer ranges considering that the reticle measurements present various increments which vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These types of glass are handy for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who desire a clearer optic sight picture without area taken up by the larger sized FFP reticle
Optic Zoom
The amount of zoom a scope provides is figured out 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.
Info About Single Power Lens Rifle Optics
A single power rifle scope comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change considering that it is fixed.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will note the zoom amount in a format such as 2-10×32. These numbers indicate the magnification of the scope could be changed in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power modification is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some advised scope power settings and the ranges where they may be efficiently used. Keep in mind that high magnification optics will not be as efficient as lower magnification level optics since increased zoom can be a bad thing. The same concept relates to longer ranges where the shooter needs to have enough power to see where to properly aim the rifle.
About Glass Lens Finishes
All top teir rifle optic and scope lenses are coated. Lens covering can be a crucial aspect of a shooting platform when purchasing high end rifle optics and scope setups.
Info on Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishings which use different techniques, chemicals, polarizations, and elements to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Scope Lens Single Finishing Versus Multi-Coating
Different optic lenses can likewise have various finishes used to them. All lenses usually have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope company and how much you spent paying for it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can establish that a company is taking several steps to combat various natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always suggest the multi-coated lens will perform better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment techniques and the quality of products used in developing the rifle glass.
Anti-water Lens Covering
Water on a scope’s lens does not improve maintaining a clear sight picture through a scope whatsoever. Numerous top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the surface area of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Installing solutions for scopes can be found in a couple of 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 typically come in quick release versions which use toss levers which allow rifle shooters to quickly install and dismount the scope.
Hex Key Optic Ring Mounting Solutions
Basic, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These types of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This form of scope mount is great for rifle systems which are in need of a durable, hard use mount which will not change no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should have for a specialized optics setup on a far away hunting or competition long gun that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to keep the hex screw threads from backing out after they are mounted safely in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping accuracy. These types of mounts come in convenient for shooting platforms which are transferred a lot, to remove the optic from the rifle for protection, or for sight systems which are employed in between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can ruin a day of shooting and your highly-priced optic by causing fogging and making residue within the scope’s tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof. Normally, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample humidity prevention for basic use rifles, unless you plan on taking your rifle sailing and are concerned about the optic still working if it goes over the side and you can still rescue the gun.
Gas Purged Rifle Optic Tubes
Another element of avoiding the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the optic is less influenced by climate changes and pressure variations from the external environment which could potentially enable 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.
