Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification by employing a series of lenses within the scope. The scope’s positioning can be adapted to account for different natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes have about 11 parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has establishes where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It simply indicates the reticle is behind or ahead of the magnification lens of the scope. Deciding upon the very best kind of rifle glass is based on what variety of hunting or shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are small
- Experienced shooters who understand their target “hold over” plus “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to remain at the same size relative to the amount of zoom being used. The end result is that the reticle dimensions adapt based upon the zoom used to shoot over greater ranges given that the markings present distinct increments which differ with the zoom level. 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 reticle measurement. These particular styles of glass work for:
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without space used up by the larger sized FFP reticle
Details on Scope Zoom
The quantity of magnification a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Power Lens Glass
A single power rifle scope and optic will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is fixed.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification degree in a format like 2-10×32. These numbers imply the magnification of the scope can be adjusted in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adaptation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some advised scope powers and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification scopes because too much zoom can be a bad thing. The same idea relates to extended distances where the shooter needs sufficient power to see precisely where to properly aim the rifle at the target.
Lens Finishing for Rifle Optics
All present day rifle scope and optic lenses are layered. Lens finishing can be a crucial element of a rifle when thinking about high end rifle optics and scope setups.
ED Versus HD Rifle Scopes
Some scope producers likewise use “HD” or high-definition lens finishes which use various procedures, components, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
About Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishes used to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering 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 upon the scope producer and just how much you spent for it. The scope’s maker and cost are indications of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Finishing for Rifle Scopes
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering.
Rifle Optic Installation Options
Installing solutions for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release variations which use toss levers which allow rifle operators to rapidly mount and dismount the scopes.
Hex Key Scope Rings
Basic, clamp type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This form of scope mount is ideal for rifle systems which are in need of a long lasting, rock solid mount which will not shift despite how much the scope is moved or abuse the rifle takes. These are the style of mounts you should have for a devoted scope system on a far away hunting or competition firearm that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to protect against the hex screw threads from backing out after they are mounted firmly in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for long guns which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Info Around Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day on the range and your expensive optic by inducing fogging and developing residue within the scope tube. Many scopes prevent humidity from going into the optical tube with a system 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 humidity avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it goes over the side and you can still rescue the firearm.
Info Around Glass Tube Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the glass is less affected by temp alterations and pressure variations from the outdoor environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
