Rifle Optic Info
Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by making use of a set of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous natural aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes and optics have about eleven parts which are arranged within and externally on the optic. These parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of optics.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Glass Details
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who understand their aim point “hold over” and “lead” ratios for their rifles
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same dimensions in connection with the volume of zoom being used. The result is that the reticle measurements alter based upon the zoom used to shoot over greater distances since the markings present different increments which change with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular sorts of glass are handy for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who select a clearer optic picture with less space taken up by the larger size FFP reticle
Magnification for Glass
The amount of zoom a scope provides is identified by the diameter, thickness, 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 Glass
A single power rifle scope will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not adjust considering that it is a fixed power optic.
Variable Power Lens Optic Details
Variable power rifle scopes can be modified between magnified levels. The power change is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some recommended scope power levels and the ranges where they could be efficiently used. Bear in mind that high magnification optics and scopes will not be as practical as lower powered glass due to the fact that increased magnification can be a bad thing. The very same idea applies to longer ranges where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Info on Lens Coatings
All state-of-the-art rifle scope and optic lenses are coated. Lens covering can be a crucial aspect of a shooting platform when looking at high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens coverings which use various methods, aspects, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Scope Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishings used to them. All lenses usually have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to 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 similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Details on Anti-water Coating
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Options for Installing Scopes on Long Guns
Installing solutions for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use manual levers which permit rifle operators to quickly mount and remove the scope.
Scope Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is great for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a similar design mount. These types of mounts are handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Details on Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope Tubes
Another part of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less influenced by temperature shifts and pressure distinctions from the outside environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
