Rifle Scope Details
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a set of lenses within the scope. The scope’s alignment can be adjusted to account for different natural considerations like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around 11 parts which are located internally and externally on the scope. These optic pieces include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. Learn about the eleven parts of glass.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has determines where the reticle or crosshair is located in regard to the scopes magnification. It actually suggests the reticle is situated behind or ahead of the magnifying lens of the scope. Picking out the very best form of rifle scope is based on what variety of hunting or shooting you intend on doing.
First Focal Plane Scopes
First focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. This triggers the reticle to stay at the same scale in relation to the quantity of zoom being used. The end result is that the reticle measurements adapt based upon the zoom applied to shoot over longer ranges due to the fact that the reticle measurements represent various increments which change with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of glass work for:
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who want a clearer optic sight picture with less area taken up by the larger size FFP reticle
Zoom for Rifle Optics
The quantity of magnification a scope offers is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Optic Info
A single power rifle scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is fixed.
Variable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the magnification degree in a format like 2-10×32. These numbers suggest the zoom of the scope could be changed in between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adaptation is accomplished using the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Glass Power Level and Ranges
Here are some recommended scope power settings and the ranges where they may be efficiently used. High power rifle scope glass will not be as effective as lower magnification glass considering that too much zoom can be a bad thing. The same goes for longer distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
Rifle Optic Lens Covering
All contemporary rifle optic lenses are layered. There are various types and qualities of glass coatings. Lens finishing is a crucial element of a rifle when thinking of high-end rifle optics and targeting equipment. The lenses are among the most significant pieces of the glass because they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens surface and also assists with anti glare from refracted direct sunlight and color perception.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens finishings which use different techniques, chemicals, polarizations, and components to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Optic Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a coating put on it so that the lens will be efficiently usable in lots of kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope company and just how much you spent paying for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has multiple treatments applied to them. If a lens gets several treatments, it can establish that a manufacturer is taking multiple actions to combat various natural elements like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not always indicate 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 glass used in constructing the rifle optic.
Hydrophobic Lens Covering
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Choices for Mounting Optics on Long Guns
Installing solutions for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release variations which use manual levers which allow rifle shooters to quickly install and dismount the scopes.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp style 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 are designed for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Several 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 carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles.
About Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can ruin a day of shooting and your expensive optic by causing fogging and generating residue inside of the scope’s tube. The majority of scopes prevent moisture from entering the optical tube with a system of sealing O-rings which are water resistant. Usually, these optics can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for common use rifles, unless you plan on taking your rifle sailing and are worried about the scope still performing if it goes overboard and you can still salvage the firearm.
Gas Purged Optic Tubes
Another component of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less influenced by climate alterations and pressure variations from the external environment which might possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
