Information About Scopes
Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s alignment can be adapted to take into account various ecological considerations like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes and optics have about eleven parts which are arranged inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. See all eleven parts of a rifle scope.
About Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the perfect type of rifle scope is based around what type of shooting you plan on doing.
About First Focal Plane Glass
First focal plane scopes (FFP) include the reticle in front of the magnifying lens. This triggers 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 distance as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who know their target “hold over” and also “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom 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 reticle measurement.
- Far away types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots occur within much shorter proximities and ranges
- Shooters who desire a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Details on Glass Magnification
The quantity of magnification a scope offers is figured out 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.
Single Power Lens Rifle Glass
A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change because it is fixed.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope powers and the distances where they may be efficiently used. Highly magnified optics will not be as useful as lower magnification scopes given that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea applies to extended distances where the shooter needs adequate power to see where to best aim the rifle at the target.
Lens Finish for Scopes
All modern-day rifle optic lenses are covered. Lens finish can be an essential element of a rifle’s setup when purchasing high end rifle optics and scope equipment.
HD Versus ED Lenses
Some rifle scope producers also use “HD” or high-definition glass coverings which employ different procedures, components, polarizations, and chemicals to enhance separate color ranges and viewable target visibility through the lens. This HD finishing is commonly used with more costly high density lens glass which lowers light’s potential to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with hard edges and outlines as light hits the item from particular angles.
Optic Lens Single Finish Versus Multi-Coating
Various scope lenses can even have various coatings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on an optical lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line or high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface area of the Steiner scope lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Optics on Firearms
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use throw levers which permit rifle operators to quickly install and remove the glass.
Hex Key Glass Rings
Standard, clamp design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of independent rings to support the optic, and are made from 7075 T6 billet aluminum which are made for long distance precision shooting. This kind of scope mount is ideal for rifles which need a durable, rock solid mount which will not shift no matter just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a devoted optics setup on a far away scouting or tournament firearm that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
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. Multiple scopes can also be swapped out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly 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 preserving accuracy. These types of mounts come in practical for rifles which are transferred a lot, to remove the scope from the rifle for protection, or for aiming systems which are employed between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day on the range and your costly optic by causing fogging and producing residue within the scope’s tube. A lot of scopes prevent wetness from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still performing if it is submerged in water and you can still find the rifle.
Gas Purged Rifle Scope Tubes
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less altered by temperature level changes and pressure variations from the outside environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
