All About Rifle Scopes
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through magnification by using a series of lenses inside the scope. The scope’s positioning can be dialed in to account for varied environmental things like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have about eleven parts which are found internally and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle glass is based on what type of shooting you plan on doing.
About First Focal Plane Glass
First focal plane optics (FFP) feature the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based on the extent of zoom 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 one hundred yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” equations for their firearm
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who want a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Details on Rifle Scope Magnification
The quantity of scope zoom you need on your optic is based on the form of shooting you intend to do. Virtually every type of rifle glass provides some level of magnification. The level of magnification a scope gives is determined by the dimension, thickness, and curvatures of the lenses inside of the rifle optic. The magnification of the scope is the “power” of the glass. This implies what the shooter is checking out through the scope is magnified times the power aspect of what can generally be seen by human eyes.
About Single Power Lens Rifle Glass
A single power rifle optic uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust considering that it is a set power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is accomplished by using 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 settings and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower powered glass considering too much magnification can be a bad thing. The same concept goes for extended ranges where the shooter needs enough power to see precisely where to best aim the rifle.
Glass Lens Finishing
All modern-day rifle scope lenses are covered. Lens covering can be a significant element of a rifle when thinking about high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some rifle glass producers additionally use “HD” or high-definition glass finishings which employ various procedures, chemicals, polarizations, and aspects to draw out different color ranges and viewable target visibility through the lens. This high-def covering is often used with more costly, high density glass which decreases light’s potential to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over objects with defined outlines as light hits the item from certain angles.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can even have various coverings applied to them. All lenses typically have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in many kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Optic Lens Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic covering.
Alternatives for Mounting Optics on Firearms
Installing options for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also usually are made in quick release versions which use manual levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Scope Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope mount is fine for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a similar style mount, several scopes can often be swapped out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining the original sighting settings. These types of mounts come in convenient for shooting platforms which are transferred between vehicles a lot, to take off the scope glass from the rifle for protection, or for optics which are utilized between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day on the range and your expensive optic by resulting in fogging and producing residue inside of the scope’s tube. A lot of scopes prevent moisture from going into the optical tube with a series of sealing O-rings which are waterproof. Typically, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness prevention for standard use rifles, unless you plan on taking your rifle on your motorboat and are concerned about the scope still performing if it is submerged in water and you can still rescue the rifle.
About Rifle Glass Tube Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the glass is less influenced by temp changes and pressure differences from the outdoor environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
