Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of different ecological things like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around eleven parts which are found internally and outside of the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are low
- Experienced shooters who know their aim point “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane glass (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to remain at the same overall size relative to the volume of zoom being used. The result is that the reticle measurements change based on the magnification applied to shoot over lengthier distances considering the markings present distinct increments which can vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These styles of optics are convenient for:
- Long distance forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who like a clearer optic sight picture with less room taken up by the bigger FFP reticle
About Rifle Scope Zoom
The quantity of magnification a scope supplies is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optic Info
A single power rifle scope and optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power scope.
Info About Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the zoom amount in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be changed in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power shift is accomplished utilizing the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some advised scope powers and the ranges where they can be successfully used. Consider that high magnification scopes and optics will not be as practical as lower magnification level scope and optics since too much magnification can be a bad thing. The same concept goes for longer distances where the shooter needs to have enough power to see where to best aim the rifle.
Details on Rifle Glass Lens Finish
All cutting-edge rifle scope lenses are covered. Lens finish is a significant element of a rifle system when looking into high end rifle optics and scope systems.
About Rifle Glass Lens Coatings – HD Versus ED
Some scope producers even use “HD” or high-definition lense coverings that take advantage of different procedures, polarizations, elements, and chemicals to extract different colors and viewable definition through lenses. This high-def covering is often used with higher density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be obvious around things with defined outlines as light hits the item from various angles.
Single Finish Versus Multi-Coating for Glass
Various optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can safeguard 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 layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Glass Lens Finish
Water on an optical lens doesn’t support preserving a clear sight picture through an optic at all. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Optics on Long Guns
Installing approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use throw levers which permit rifle shooters to rapidly mount and dismount the scope.
Hex Key Scope Ring Mounts
Normal, 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 made from 7075 T6 billet aluminum which is designed for long range accuracy shooting. This type of scope install is perfect for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
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. If they all use a comparable style mount, a number of scopes can also be switched on the range. The quick detach mount style 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 keeping precision. These types of mounts come in beneficial for shooting platforms which are transferred a lot, to take off the scope glass from the rifle for protection, or for optics which are adopted in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can spoil a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture avoidance for conventional use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it is submerged in water and you can still find the firearm.
Details on Scope Tube Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less affected by climate changes and pressure variations from the outside environment which may possibly allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
