What You Need to Know About Scopes
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of varied natural considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have about eleven parts which are found internally and outside of the optic. These parts include the rifle scope’s body, lenses, modification dials, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane a scope has decides where the reticle or crosshair is located in regard to the scopes zoom. It literally implies the reticle is situated behind or ahead of the magnifying lens of the optic. Considering the most effective kind of rifle scope is dependent on what style of hunting or shooting you plan on undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are small
- Experienced shooters who recognize their aim point “hold over” as well as “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who prefer a clearer optic picture without room taken up by the larger size FFP reticle
Zoom for Rifle Scopes
The quantity of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Single Power Lens Rifle Scopes
A single power rifle scope and optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is fixed.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes can be changed between magnification levels. It will list the zoom degree in a configuration like 2-10×32. These numbers mean the zoom of the scope could be set between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power modification is achieved using the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power and Range of Rifle Glass
Here are some recommended scope power levels and the ranges where they may be effectively used. Bear in mind that high magnification optics and scopes will not be as practical as lower powered optics due to the fact that increased zoom can be a detractor. The same concept applies to longer ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Rifle Scope Lens Finishing
All contemporary rifle scope lenses are coated. There are different types and qualities of lens coverings. Lens finish is an essential element of a rifle’s setup when thinking about high end rifle optics and scope units. The lenses are among the most crucial components of the glass considering that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens surface as well as improves anti glare from refracted light and color recognition.
HD Versus ED Glass Lens Coatings
Some scope brands also use “HD” or high-definition lens coverings which use different methods, polarizations, chemicals, and components to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Optic Lens Covering Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them before being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It needs to have a finishing placed on it so that it will be optimally usable in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less useful 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 makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Details on Hydrophobic Covering
Water on a scope lens doesn’t assist with retaining a clear sight picture through a scope at all. Numerous top of the line or premium scope producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface area of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Rifle Optic Installation Options
Mounting options for scopes can be found in a few options. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release versions which use toss levers which allow rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is perfect for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, a number of scopes can often be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top type 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 keeping accuracy. These kinds of mounts come in convenient for shooting platforms which are transported a lot, to take off the optic from the rifle for protection, or for sight systems which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. Many optics protect against wetness from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, 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 sufficient humidity avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are concerned about the scope still functioning if it goes over the side and you can still recover the gun.
Glass Gas Purging
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the optic is less altered by temp changes and pressure differences from the external environment which could potentially enable water vapor to seep 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.
