What You Need to Know About Scopes
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of various ecological considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around eleven parts which are arranged internally and externally on the scope. These parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane a scope has decides where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It simply indicates the reticle is behind or before the magnification lens of the optic. Selecting the very best form of rifle glass depends upon what type of hunting or shooting you anticipate undertaking.
First Focal Plane Optic Details
First focal plane optics (FFP) come with the reticle ahead of the magnification lens. This induces the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are low
- Experienced shooters who know their aim point “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the magnifying lens. This induces the reticle to stay at the exact same size in connection with the amount of zoom being used. The result is that the reticle measurements adapt based on the zoom employed to shoot over longer ranges considering the reticle markings represent various increments which can vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of scopes work for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who would like a clearer optic sight picture with less area taken up by the larger size FFP reticle
Zoom for Glass
The measure of scope magnification you need on your glass depends upon the form of shooting you wish to do. Virtually every type of rifle glass gives some degree of zoom. The level of zoom a scope supplies is established by the dimension, thickness, and curvatures of the lens glass within the rifle optic. The magnification of the scope is the “power” of the scope. This suggests what the shooter is checking out through the scope is magnified times the power factor of what can usually be seen by human eyes.
Single Power Lens Scope Details
A single power rifle optic and scope will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate considering that it is fixed.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Glass Power and Ranges
Here are some advised scope power settings and the distances where they could be effectively used. Highly magnified scopes will not be as efficient as lower magnification level scopes since too much zoom can be a bad thing. The exact same idea goes for extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle.
Details on Lens Coatings
All contemporary rifle optic lenses are coated. Lens finishing can be a vital aspect of a rifle when purchasing high end rifle optics and scope equipment.
Info on Scope Lens Coatings – HD Versus ED
Some rifle scope manufacturers also use “HD” or high-definition lense finishes which make the most of different processes, aspects, polarizations, and chemical applications to extract different color ranges and viewable target definition through the lens. This HD covering is normally used with more costly, high density glass which drops light’s ability to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often visible over objects with hard edges and shapes as light hits the item from specific angles.
Rifle Optic Lens Single Finishing Versus Multi-Coating
Different scope lenses can even have different coverings applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in numerous kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope maker and how much money you spent for it. Both are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coating
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 scope makers will coat their lenses with a hydrophilic or hydrophobic anti-water finish.
Scope Installation Options
Installing options for scopes can be found in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use manual levers which enable rifle shooters to quickly install and dismount the optics.
Glass Mounts with Hex Key Rings
Standard, clamp design mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use double independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This type of scope mount is excellent for rifles which need to have a long lasting, hard use mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the type of mounts you should have for a faithful scope system on a far away hunting or hard target interdiction firearm which will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to keep the hex screw threads from backing out after they are installed safely in place. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between numerous rifles or are situationally focused.
Info on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your highly-priced optic by resulting in fogging and generating residue inside of the scope tube. Many scopes protect against moisture from entering the optical tube with a series of sealing O-rings which are waterproof. Normally, these scopes can be submerged within 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 for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are concerned about the scope still performing if it is submerged in water and you can still salvage the gun.
Gas Purged Rifle Scope Tubes
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less impacted by climate changes and pressure variations from the external environment which might potentially permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
