What You Need to Know About Rifle Scopes
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by employing a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of varied ecological factors like wind and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have about eleven parts which are located within and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has identifies where the reticle or crosshair is located in connection with the scopes zoom. It simply indicates the reticle is behind or before the magnification lens of the optic. Picking out the most effective form of rifle glass is dependent on what variety of shooting or hunting you intend on undertaking.
First Focal Plane Scopes
First focal plane glass (FFP) include the reticle before the magnification lens. This causes 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 magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the magnification 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 measurement.
- Long distance types of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who would like a clearer optic picture without space taken up by the larger sized FFP reticle
Magnification for Rifle Scopes
The level of scope magnification you need on your glass is based on the type of shooting you plan to do. Practically every style of rifle scope provides some degree of magnification. The volume of magnification a scope provides is established by the diameter, density, and curvatures of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This indicates what the shooter is aiming at through the scope is magnified times the power factor of what can generally be seen by human eyes.
About Fixed Power Lens Glass
A single power rifle scope or optic will have 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 adjust because it is fixed.
About Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the zoom amount in a format like 2-10×32. These numbers mean the magnification of the scope could be adjusted between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adaptation is achieved by applying the power ring component of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope powers and the distances where they may be effectively used. Always remember that high power scopes will not be as practical as lower magnification level optics due to the fact that excessive magnification can be a negative thing in certain situations. The very same idea goes for longer distances where the shooter needs to have adequate power to see where to properly aim the rifle.
Details on Scope Lens Coating
All cutting-edge rifle glass lenses are layered. Lens covering can be an important aspect of a rifle’s setup when thinking about high end rifle optics and scope equipment.
ED Versus HD Rifle Glass
Some scope producers also use “HD” or high-definition lens finishes which use various procedures, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Glass Lens Finish Versus Multi-Coating
Various optic lenses can even have different finishes applied to them. All lenses usually have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t simply 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 efficiently functional in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
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 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 define if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Rifle Scope Lens Finishing
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic covering.
Alternatives for Mounting Rifle Scopes on Firearms
Mounting options for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release variations which use throw levers which permit rifle shooters to quickly install and dismount the glass.
Hex Key Scope Ring Mounts
Normal, clamp design 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is excellent for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a similar design mount, several scopes can often be swapped out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts are useful and convenient for rifles which are carried a lot, to take off the glass from the rifle for protection, or for scopes which are employed in between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your expensive optic by inducing fogging and producing residue within the scope’s tube. Many optics prevent moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for standard use rifles, unless you anticipate taking your rifle on a boat and are worried about the optic still functioning if it goes over the side and you can still find the firearm.
Gas Purged Scope Tubes
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the glass is less influenced by temp changes and pressure distinctions from the outside environment which could possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
