What You Need to Know About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification using a series of lenses inside the scope. The scope’s alignment can be adapted for the consideration of separate natural aspects like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about 11 parts which are arranged inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair lies relative to the scopes zoom. It simply means the reticle is behind or before the magnifying lens of the optic. Picking the most suitable form of rifle scope is dependent on what style of shooting you anticipate undertaking.
Info on First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle behind the magnification lens. This causes the reticle to stay at the same size relative to the volume of zoom being used. The outcome is that the reticle dimensions adapt based upon the magnification applied to shoot over greater ranges since the reticle measurements represent distinct increments which can vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of glass work for:
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who want a clearer optic picture with less area used up by the larger sized FFP reticle
Zoom for Optics
The amount of zoom a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change considering that it is a set power scope.
Adjustable Power Lens Glass
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Glass
Here are some advised scope powers and the ranges where they may be successfully used. Keep in mind that higher magnification glass will not be as effective as lower powered scopes because increased magnification can be a detractor. The exact same concept goes for longer distances where the shooter needs to have enough power to see exactly where to best aim the rifle.
Info on Lens Covering
All modern-day rifle optic lenses are layered. Lens finish can be a vital element of a shooting platform when considering high end rifle optics and scope setups.
HD Versus ED Rifle Optic Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishes which use different procedures, aspects, chemicals, and polarizations to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Rifle Optic Lens Finishing Versus Multi-Coating
Various scope lenses can also have various coverings applied to them. All lenses generally have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a finishing applied to it so that the lens will be efficiently functional in lots of types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a company is taking multiple steps to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not necessarily suggest the multi-coated lens will perform better than a single covered lens. Being “much better” depends on the maker’s lens treatment techniques and the quality of glass used in building the rifle glass.
Hydrophobic Optic Lens Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Alternatives for Installing Rifle Scopes on Firearms
Mounting options for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use toss levers which allow rifle shooters to rapidly mount and dismount the scope.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is great for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be switched on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving precision. These types of mounts are useful and convenient for shooting platforms which are hauled around a lot, to take off the optic from the rifle for protection, or for sight systems which are adopted between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. A lot of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Info on Glass Tube Gas Purging
Another element of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less affected by climate changes and pressure differences from the outside environment which may potentially allow water vapor to permeate 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.
