Information About Optics
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account different natural aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have about 11 parts which are found inside and outside of the optic. These parts include the rifle scope’s body, lenses, modification dials, objective focus rings, and other elements. See all eleven parts of scopes.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the perfect type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at 100 yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are low
- Experienced shooters who know their target “hold over” and also “lead” ratios for their long gun
- Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This causes the reticle to remain at the same overall size in relation to the quantity of zoom being used. The outcome is that the reticle dimensions adapt based upon the magnification used to shoot over greater distances considering that the reticle measurements represent distinct increments which can vary with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular kinds of scopes are beneficial for:
- Far away forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who want a clearer optic sight picture without space taken up by the enlarged FFP reticle
Zoom for Rifle Scopes
The quantity of zoom a scope offers is determined by the diameter, 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 Scope Facts
A single power rifle optic will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is a fixed power scope.
Info on Variable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power adjustment is performed by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some recommended scope power settings and the distances where they could be efficiently used. High power glass will not be as effective as lower magnification scopes because too much magnification can be a negative aspect depending on your shooting distance. The same concept goes for extended ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Lens Covering for Rifle Optics
All current rifle scope and optic lenses are layered. Lens covering can be an essential element of a rifle’s setup when buying high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens finishings which use various methods, chemicals, polarizations, and elements to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating for Rifle Optics
Various optic lenses can also have various coatings applied to them. All lenses usually have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and just how much you spent on it. Both are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has multiple treatments applied to them. If a lens gets several treatments, it can establish that a producer is taking numerous actions to fight different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also does not always mean the multi-coated lens is better than a single coated lens. Being “better” hinges on the manufacturer’s lens treatment techniques and the quality of products used in building the rifle glass.
Anti-water Lens Coating
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Optic Installation Alternatives
Installing solutions for scopes are available in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of detached rings to support the scope, and are made from 7075 T6 billet aluminum which are developed for far away accuracy shooting. This form of scope mount is ideal for rifles which require a long lasting, hard use mount which will not shift despite how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a devoted scope system on a reach out and touch someone hunting or competition rifle that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are installed safely in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Info Around Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the glass is less impacted by condition shifts and pressure variations from the external environment which could possibly 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.
