All About Rifle Scopes
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a series of lenses within the scope. The scope’s alignment can be adapted to account for various natural factors like wind and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes have around eleven parts which are located internally and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other parts. See all eleven parts of scopes.
About Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes 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 distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and takes up more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. This causes the reticle to remain at the same scale relative to the volume of magnification being used. The end result is that the reticle measurements adjust based upon the magnification used to shoot over greater ranges because the reticle markings present distinct increments which fluctuate with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular sorts of glass work for:
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who like a clearer optic picture without space taken up by the larger size FFP reticle
Scope Zoom
The quantity of zoom a scope provides is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust considering that it is a fixed power optic.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification increments. It will note the zoom amount in a format such as 2-10×32. These numbers imply the zoom of the scope can be adjusted between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adjustment is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Ranges
Here are some suggested scope power settings and the ranges where they could be efficiently used. Consider that high magnification optics will not be as effective as lower powered scope and optics because too much zoom can be a negative thing in certain situations. The same applies to extended ranges where the shooter needs increased power to see exactly where to best aim the rifle.
Lens Finish for Rifle Scopes
All cutting-edge rifle optic and scope lenses are layered. Lens covering can be a significant aspect of a rifle’s setup when looking at high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens coverings which use various methods, chemicals, elements, and polarizations to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Scope Lens Coating Versus Multi-Coating
Various scope lenses can also have various finishes applied to them. All lenses usually have at least some type of treatment or finishing applied to them before 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 becomes part of the finely tuned optic. It needs to have a covering placed on it so that the lens will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can safeguard 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 covered or “multi” coated. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can indicate that a manufacturer is taking multiple steps to fight various natural elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally doesn’t always indicate the multi-coated lens is much better than a single coated lens. Being “better” depends on the producer’s lens treatment techniques and the quality of products used in creating the rifle glass.
Anti-water Lens Coverings
Water on a lens does not help with maintaining 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.
Choices for Mounting Scopes on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use toss levers which allow rifle shooters to rapidly install and dismount the glass.
Hex Key Glass Ring Mounts
Standard, clamp-on style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use double independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This kind of scope mount is effective for rifles which are in need of a long lasting, hard use mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you should get for a dedicated optics setup on a long distance hunting or competition firearm which will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screws from backing out after they are mounted safely in position. An example of these rings are the 30mm style made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types 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 similar style mount, multiple scopes can often be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely 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 maintaining accuracy. These types of mounts come in practical for shooting platforms which are transferred a lot, to take off the optic from the rifle for protection, or for aiming systems which are used between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day on the range and your highly-priced optic by triggering fogging and generating residue within the scope’s tube. Many scopes protect against humidity from entering the scope tube with a system of sealing O-rings which are waterproof. Normally, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture prevention for common use rifles, unless you intend on taking your rifle sailing and are concerned about the optic still performing if it is submerged in water and you can still retrieve the firearm.
Rifle Optic Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less influenced by temp changes and pressure variations 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.
