What You Need to Know About Rifle Optics
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to account for numerous ecological factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes and optics have about eleven parts which are arranged inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has determines where the reticle or crosshair lies in relation to the optic’s magnifying adjustments. It literally indicates the reticle is located behind or before the magnification lens of the optic. Deciding on the most effective form of rifle scope is based upon what sort of shooting you anticipate doing.
Info on First Focal Plane Optics
First focal plane optics (FFP) come with the reticle before 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 range as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. This induces the reticle to remain at the very same overall size in relation to the amount of zoom being used. The outcome is that the reticle dimensions shift based upon the zoom employed to shoot over longer distances due to the fact that the reticle markings represent various increments which differ with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These kinds of scopes are useful for:
- Far away types of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who desire a clearer optic picture without space taken up by the bigger FFP reticle
Magnification for Glass
The extent of scope magnification you need is based on the kind of shooting you intend to do. Practically every style of rifle scope gives some degree of magnification. The level of zoom a scope gives is established by the dimension, density, and curves of the lenses within the rifle scope. The magnification level of the scope is the “power” of the glass. This suggests what the shooter is looking at through the scope is amplified times the power element of what can usually be seen by human eyes.
Info on Fixed Power Lens Scopes
A single power rifle scope or optic uses 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 zoom of this kind of optic can not change because it is a set power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power adjustment is handled using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power settings and the distances where they can be effectively used. Highly magnified optics will not be as useful as lower magnification rifle scope glass because too much magnification can be a negative aspect depending on your shooting distance. The exact same concept applies to extended ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle at the target.
About Rifle Scope Lens Finishing
All top teir rifle glass lenses are coated. Lens coating is a significant aspect of a shooting platform when looking at high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coatings which use different processes, polarizations, components, and chemicals to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
What to Know About Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different coatings applied to them. All lenses generally 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 safeguard the lens from scratches while decreasing 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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Finish
Water on an optic’s lens doesn’t support maintaining a clear sight picture through an optic in any way. Numerous top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the surface of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Optic Installing Choices
Mounting approaches for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release variations which use toss levers which permit rifle shooters to quickly install and dismount the optics.
Rifle Scope Mounts with Hex Key Rings
Basic, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance precision shooting. This kind of scope mount is excellent for rifle systems which need to have a long lasting, unfailing mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a specialized scope system on a long distance hunting or sniper competition long gun which will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used to prevent the hex screw threads from wiggling out after they are installed firmly in place. An example of these rings are the 30mm type made by the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched on the range. 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, removed from the rifle, and remounted while keeping precision. These types of mounts come in beneficial for shooting platforms which are moved a lot, to remove the scope glass from the rifle for protection, or for sight systems which are used in between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle glass can mess up a day of shooting and your pricey optic by inducing fogging and producing residue inside of the scope’s tube. Most optics protect against wetness from going into the optical tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture prevention for common use rifles, unless you anticipate taking your rifle on boats and are concerned about the scope still functioning if it falls overboard and you can still rescue the firearm.
Gas Purged Rifle Optic Tubes
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the optic is less impacted by temp shifts and pressure distinctions from the outdoor environment which might potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
