Scope Facts
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of various natural considerations like wind and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around eleven parts which are located internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Optics
First focal plane scopes (FFP) feature the reticle ahead of the zoom lens. This triggers the reticle to increase in size based on the level of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who recognize their aim point “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and proximities
- Shooters who choose a clearer optic picture with less room used up by the larger size FFP reticle
About Optic Magnification
The amount of zoom a scope provides is determined by the diameter, thickness, 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 Optics
A single power rifle scope and optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is fixed.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes can be tweaked between magnified settings. The power change is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the distances where they could be successfully used. High power rifle scope glass will not be as efficient as lower magnification level rifle scope glass because too much zoom can be a bad thing. The very same idea applies to longer ranges where the shooter needs sufficient power to see precisely where to best aim the rifle.
Lens Coating for Optics
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of coatings. Lens finish can be a crucial element of a rifle when contemplating high-end rifle optics and targeting systems. The lenses are one of the most key components of the optic since they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses protects the lens surface and helps with anti glare from excess light and color perception.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coverings which use different methods, elements, polarizations, and chemicals to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or covering used to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial 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 similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Glass Lens Finishing
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Glass Installation Choices
Mounting options for scopes come in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use manual levers which enable rifle shooters to rapidly mount and remove the scopes.
Hex Key Rifle Scope Rings
Standard, clamp-on style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This form of scope mount is ideal for rifle systems which need a durable, hard use mount which will not move regardless of how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should get for a specialized scope setup on a long distance hunting or competitors rifle that will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to stop the hex screw threads from wiggling out after they are mounted firmly in position. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set typically costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a similar design mount, several scopes can also be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining the original sighting settings. These types of mounts are useful and handy for shooting platforms which are moved a lot, to take off the scope from the rifle for protection, or for sight systems which are utilized in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day on the range and your expensive optic by inducing fogging and developing residue inside of the scope tube. The majority of scopes prevent humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Usually, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness prevention for conventional use rifles, unless you anticipate taking your rifle boating and are concerned about the optic still working if it goes over the side and you can still rescue the firearm.
Gas Purged Glass Tubes
Another part of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the optic is less affected by condition changes and pressure variations from the outside environment which may potentially allow 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 look for.
