Rifle scopes enable you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom using a series of lenses inside the scope. The scope’s alignment can be adapted for the consideration of various environmental considerations 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 upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes have around eleven parts which are found inside and externally on the scope. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. See all eleven parts of a rifle scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the optimal type of rifle glass is based around what type of shooting you plan on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the enhanced 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 same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who know their target “hold over” and also “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle behind the zoom lens. This induces the reticle to remain at the same dimensions relative to the amount of zoom being used. The effect is that the reticle measurements adapt based upon the magnification applied to shoot over lengthier distances considering the reticle markings represent various increments which change with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular types of optics work for:
- Long distance forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who would like a clearer optic picture with less area taken up by the larger size FFP reticle
Rifle Scope Zoom
The extent of scope magnification you need on your optic depends upon the style of shooting you intend to do. Pretty much every kind of rifle scope offers some amount of zoom. The volume of zoom a scope offers is established by the dimension, thickness, and curves of the lens glass within the rifle scope. The magnification of the optic is the “power” of the scope. This signifies what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Rifle Optic Details
A single power rifle scope comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate considering that it is a set power scope.
Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification amount in a format like 2-10×32. These numbers imply the magnification of the scope could be set in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power adaptation is achieved utilizing the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some advised scope powers and the distances where they could be effectively used. Keep in mind that high power scopes and optics will not be as efficient as lower powered 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 extended ranges where the shooter needs to have increased power to see precisely where to best aim the rifle.
Info on Rifle Scope Lens Finish
All modern-day rifle optic lenses are layered. There are various types and qualities of glass lens finishings. Lens finish can be a crucial aspect of a rifle when thinking about high end rifle optics and targeting units. The glass lenses are one of the most important components of the optic because they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens exterior as well as helps with anti glare from excess sunlight and color presence.
Details on Glass Lens Coatings – HD Versus ED
Some rifle glass companies additionally use “HD” or high-definition lens coverings which use different procedures, rare earth compounds, polarizations, and components to extract a wide range of colors and viewable target visibility through lenses. This high-def finishing is typically used with higher density glass which brings down light’s chance to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be obvious around objects with defined shapes as light hits the item from specific angles.
Details on Single Covering Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses normally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It needs to have a covering applied to it so that it will be optimally functional in numerous kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering 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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Finishes
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Scope Installation Alternatives
Installing approaches for scopes are available in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use toss levers which allow rifle shooters to rapidly mount and dismount the optics.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use two separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This kind of scope mount is great for rifle systems which are in need of a long lasting, hard use mount which will not change despite just how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a dedicated scope system on a far away scouting or competition rifle that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to protect against the hex screw threads from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These kinds of mounts come in handy for rifles which are hauled around a lot, to remove the optic from the rifle for protection, or for aiming systems which are employed between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can mess up a day of shooting and your costly optic by resulting in fogging and producing residue within the scope tube. Many scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are concerned about the optic still performing if it falls overboard and you can still find the gun.
Gas Purged Glass Tubes
Another component of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the optic is less affected by climate changes and pressure differences from the outdoor environment which may potentially allow 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 look for.
