Info Optics
Rifle scopes allow you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom using a set of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of various natural aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have around eleven parts which are located internally and externally on the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. See all eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle optic is based on what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who understand their aim point “hold over” and also “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom 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.
- 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 distances
- Shooters who would like a clearer optic sight picture with less room taken up by the enlarged FFP reticle
Ins and Outs of Rifle Scope Magnification
The extent of scope zoom you require depends upon the form of shooting you plan to do. Nearly every type of rifle scope gives some amount of zoom. The volume of magnification a scope provides is determined by the dimension, thickness, and curvatures of the lenses within the rifle optic. The magnification level of the scope is the “power” of the glass. This signifies what the shooter is checking out through the scope is magnified times the power aspect of what can usually be seen by human eyes.
About Single Power Lens Rifle Glass
A single power rifle optic will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate given that it is set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power change is handled using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Scopes
Here are some recommended scope power levels and the distances where they can be successfully used. High power scopes will not be as effective as lower powered scopes given that too much zoom can be a negative aspect depending on your shooting distance. The same concept applies to longer distances where the shooter needs to have increased power to see precisely where to best aim the rifle.
Details on Rifle Optic Lens Coating
All modern rifle scope lenses are covered. Lens covering is an important aspect of a rifle when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coatings which use various methods, chemicals, aspects, and polarizations to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can even have different coatings applied to them. All lenses generally have at least some type of treatment or finish 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 requires a coating to be applied to it so that the lens will be efficiently functional in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing 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 maker and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has had numerous treatments applied to them. If a lens gets multiple treatments, it can show that a company is taking several actions to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally does not always mean the multi-coated lens is much better than a single layered lens. Being “much better” depends upon the manufacturer’s lens treatment solutions and the quality of components used in developing the rifle glass.
Anti-water Lens Finish
Water on a lens does not help with retaining a clear sight picture through an optic whatsoever. Many top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installing Options
Installing approaches for scopes are available in a few options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use manual levers which allow rifle shooters to rapidly mount and dismount the optics.
Hex Key Rifle Glass Rings
Basic, clamp design mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use double individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This type of scope mount is ideal for rifle systems which are in need of a long lasting, hard use mount which will not move no matter just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should have for a specialized optics setup on a far away scouting or interdiction long gun that will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screw threads from backing out after they are mounted securely in place. An example of these rings are the 30mm type from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can wreck a day of shooting and your highly-priced optic by causing fogging and making residue within the scope’s tube. Most optics prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture prevention for standard use rifles, unless you plan on taking your rifle sailing and are concerned about the scope still working if it goes over the side and you can still rescue the firearm.
Info Around Glass Tube Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less altered by temperature alterations and pressure distinctions from the outdoor environment which could possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
