What You Need to Know About Optics
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a set of lenses inside the scope. The scope’s alignment can be adapted to take into account various environmental factors like wind speed and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes have around eleven parts which are found inside and externally on the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Optic Details
Focal plane scopes (FFP) come with the reticle in front of 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 amplified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who understand their target “hold over” and also “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Glass Details
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who prefer a clearer optic picture without area taken up by the larger size FFP reticle
The measure of scope magnification you need on your optic depends upon the form of shooting you choose to do. Almost every kind of rifle optic gives some degree of magnification. The quantity of zoom a scope delivers is established by the dimension, density, and curvatures of the lenses inside of the rifle scope. The magnifying level of the optic is the “power” of the opic. This suggests what the shooter is looking at through the scope is magnified times the power factor of what can typically be seen by human eyes.
Info About Fixed Single Power Lens Rifle Scopes
A single power rifle optic or scope comes with 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 type of optic can not adjust since it is a fixed power scope.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope power settings and the distances where they can be effectively used. Keep in mind that high power optics and scopes will not be as efficient as lower magnification level optics due to the fact that too much zoom can be a bad thing. The very same idea goes for longer ranges where the shooter needs increased power to see where to properly aim the rifle at the target.
About Lens Covering
All top teir rifle optic and scope lenses are covered. Lens finish can be a significant element of a rifle system when buying high end rifle optics and scope setups.
ED Versus HD Optics
Some scope brands also use “HD” or high-definition lens finishings which use different methods, polarizations, chemicals, and components to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Scope Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a covering applied to it so that the lens will be optimally usable in numerous kinds of environments, degrees of sunlight (full light VS shaded), 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 coated 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 had several treatments applied to them. If a lens receives several treatments, it can show that a company is taking numerous steps to combat various natural elements like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally doesn’t always suggest the multi-coated lens will perform better than a single coated lens. Being “better” depends upon the maker’s lens treatment solutions and the quality of products used in developing the rifle scope.
Hydrophobic Lens Coatings
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic covering.
Alternatives for Installing Optics on Firearms
Mounting solutions for scopes are available in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally are made in quick release variations which use toss levers which allow rifle operators to quickly install and dismount the scope.
Hex Key Rifle Glass Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use double detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This kind of scope mount is effective for rifles which require a resilient, hard use mount which will not shift regardless of how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should get for a devoted optics system on a reach out and touch someone scouting or competition long gun which will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screw threads from backing out after they are installed tightly in place. An example of these rings are the 30mm style from 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 rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, several scopes can often be swapped in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely 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 back on the rifle while maintaining the original sighting settings. These types of mounts come in practical for shooting platforms which are hauled around a lot, to take off the optic from the rifle for protection, or for aiming systems which are utilized in between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the scope is less influenced by condition alterations and pressure variations from the external environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
