Optic Facts
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by employing a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of numerous natural things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern rifle optics have around 11 parts which are found inside and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle scope is based around what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. This triggers the reticle to remain at the very same scale in connection with the volume of zoom being used. The result is that the reticle dimensions shift based on the zoom employed to shoot over greater distances considering the markings present various increments which change with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These particular styles of optics work for:
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who select a clearer optic picture without room used up by the larger size FFP reticle
Rifle Glass Zoom
The amount of scope magnification you need on your optic depends upon the style of shooting you plan to do. Almost every style of rifle optic supplies some degree of magnification. The amount of zoom a scope supplies is established by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification level of the optic is the “power” of the scope. This indicates what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
About Fixed Power Lens Rifle Optics
A single power rifle scope will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change because it is a fixed power optic.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes can be changed between magnification power levels. It will list the zoom level in a format such as 2-10×32. These numbers indicate the zoom of the scope can be adjusted in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power shift is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some advised scope power settings and the distances where they may be successfully used. Keep in mind that higher magnification scopes will not be as practical as lower magnification level scopes because excessive zoom can be a detractor. The very same idea applies to longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Details on Lens Finishing
All modern rifle scope and optic lenses are layered. There are different types and qualities of glass lens finishings. When researching high end rifle optics and scope systems, Lens finish can be a significant aspect of a rifle. The glass lenses are one of the most important pieces of the optic given that they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses offers protection to the lens exterior as well as improves anti glare from excess daylight and color profiles.
Info on Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coverings which use various procedures, aspects, chemicals, and polarizations to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Info on Single Finish Versus Multi-Coating
Various optic lenses can even have different coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing applied to it so that the lens will be optimally usable in numerous kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to the surfaces. If a lens gets numerous treatments, it can establish that a maker is taking numerous steps to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not always indicate the multi-coated lens will perform better than a single covered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of glass used in building the rifle optic.
Rifle Optic Lens Hydrophobic Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Rifle Optic Installation Choices
Mounting options for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use manual levers which enable rifle operators to quickly mount and dismount the scopes.
Hex Key Glass Ring Mounts
Standard, clamp style 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 two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Many scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Optic Tube Gas Purging
Another part of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by condition alterations and pressure distinctions from the outdoor environment which may potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
