Info Rifle Optics
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of many environmental elements like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle optics have about 11 parts which are found inside and outside of the optic. These parts consist of the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other components. Learn about the eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It simply means the reticle is located behind or before the magnifying lens of the scope. Picking out the most suitable form of rifle glass is dependent on what form of shooting you intend on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are small
- Experienced shooters who understand their aim point “hold over” and also “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Scope Info
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This induces the reticle to remain at the very same overall size in connection with the volume of zoom being used. The result is that the reticle dimensions shift based on the zoom chosen to shoot over greater ranges given that the reticle measurements present distinct increments which differ 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 sorts of scopes work for:
- Far away forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who prefer a clearer optic picture with less room taken up by the larger sized FFP reticle
The quantity of scope zoom you require is based on the sort of shooting you want to do. Just about every type of rifle optic provides some degree of magnification. The amount of magnification a scope delivers is identified by the dimension, density, and curves of the lens glass inside of the rifle optic. The magnification level of the scope is the “power” of the opic. This means what the shooter is checking out through the scope is amplified times the power element of what can generally be seen by human eyes.
Info About Fixed Power Lens Rifle Glass
A single power rifle scope and optic will have a magnification 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 fluctuate since it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power change is handled 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 of Rifle Scopes
Here are some advised scope powers and the ranges where they could be efficiently used. High power optics will not be as beneficial as lower magnification rifle scope glass because too much magnification can be a bad thing. The same concept goes for extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle at the target.
Optic Lens Finishing
All present day rifle scope lenses are coated. Lens coating is an important aspect of a shooting platform when looking into high end rifle optics and scope systems.
HD Versus ED Lenses
Some rifle scope producers also use “HD” or high-def lense coverings that take advantage of different procedures, aspects, polarizations, and chemicals to enhance a wide range of color ranges and viewable target definition through the lens. This high-def finishing is often used with greater density lens glass which drops light’s potential to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often obvious around objects with hard shapes as light hits the object from particular angles.
Rifle Optic Lens Single Coating Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses normally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in many kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering 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 producer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Finish for Rifle Scopes
Water on a scope’s lens doesn’t support retaining a clear sight picture through a scope in any way. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Glass on Long Guns
Installing solutions for scopes can be found in a couple of choices. 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 usually come in quick release variations which use throw levers which allow rifle operators to rapidly install and dismount the optics.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp-on design mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This type of scope mount is great for rifles which are in need of a long lasting, hard use mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted scope system on a reach out and touch someone hunting or competition firearm which will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on screws to keep the hex screw threads from wiggling out after they are installed securely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
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. Several scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These types of mounts come in beneficial for rifles which are shipped a lot, to take off the scope from the rifle for protection, or for optics which are utilized between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can ruin a day on the range and your highly-priced optic by inducing fogging and creating residue within the scope’s tube. Most optics protect against humidity from entering the optical tube with a system of sealing O-rings which are waterproof. Usually, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles, unless you anticipate taking your rifle aboard watercrafts and are concerned about the optic still functioning if it falls overboard and you can still find the rifle.
Gas Purged Optic Tubes
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the optic is less affected by temp changes and pressure variations from the outside environment which might possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
