Rifle Scope Facts
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s alignment can be dialed in for consideration of varied natural factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern rifle optics have about eleven parts which are arranged inside and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other parts. See all eleven parts of a scope.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair is located relative to the optic’s magnification. It actually indicates the reticle is behind or in front of the magnifying lens of the scope. Choosing the most suitable kind of rifle scope depends on what style of shooting or hunting you intend on undertaking.
About First Focal Plane Optics
First focal plane optics (FFP) feature the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are minor
- Experienced shooters who have an idea for their target “hold over” and “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Optic Details
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This triggers the reticle to stay at the very same size in relation to the level of magnification being used. The effect is that the reticle measurements shift based on the zoom used to shoot over longer distances given that the reticle measurements represent distinct increments which differ with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These varieties of scopes work for:
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and spaces
- Shooters who like a clearer optic picture without space taken up by the larger size FFP reticle
Rifle Glass Zoom
The quantity of scope magnification you need on your scope depends on the kind of shooting you like to do. Pretty much every type of rifle glass gives some amount of magnification. The volume of magnification a scope offers is identified by the diameter, density, and curves of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the glass. This implies what the shooter is checking out through the scope is amplified times the power factor of what can usually be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle optic and scope 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 magnification of this kind of scope can not fluctuate since it is a fixed power optic.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the magnification level in a format such as 2-10×32. These numbers mean the zoom of the scope could be set between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power modification is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power levels and the distances where they may be efficiently used. Bear in mind that higher power scopes will not be as effective as lower magnification level optics and scopes due to the fact that too much magnification can be a negative thing in certain situations. The exact same idea applies to longer distances where the shooter needs enough power to see exactly where to properly aim the rifle.
About Lens Coatings
All modern rifle glass lenses are covered. Lens finishing can be a significant element of a rifle system when looking at high end rifle optics and scope equipment.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens finishes which use different techniques, chemicals, aspects, and polarizations to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different scope lenses can also have various coverings applied to them. All lenses generally 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 becomes part of the carefully tuned optic. It must have a finishing applied to it so that it will be efficiently usable in many types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing 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 producer and the amount you spent paying for it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Lens Finishes
Water on a scope lens does not improve maintaining a clear sight picture through an optic in any way. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface of the Steiner scope lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Optics on Firearms
Mounting options for scopes come in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use throw levers which allow rifle shooters to quickly mount and dismount the scopes.
Hex Key Rifle Glass Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 is developed for long distance precision shooting. This type of scope mount is wonderful for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a similar design mount, multiple scopes can also be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts come in convenient for rifles which are moved around a lot, to take off the optic from the rifle for protection, or for aiming systems which are employed in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Info Around Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can mess up a day on the range and your highly-priced optic by causing fogging and producing residue within the scope’s tube. Many scopes protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture avoidance for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are concerned about the scope still working if it goes over the side and you can still recover the firearm.
Info on Scope Tube Gas Purging
Another element of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less impacted by temp changes and pressure distinctions from the outside environment which might potentially enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
