What You Need to Know About Rifle Optics
Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target by utilizing a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of varied environmental aspects like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on 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 contemporary rifle scopes and optics have about eleven parts which are located inside and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other components. See all eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the finest type of rifle scope is based on what type of shooting you plan to do.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who recognize their aim point “hold over” and “lead” equations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This induces the reticle to remain at the very same size relative to the volume of magnification being used. The outcome is that the reticle measurements evolve based upon the zoom used to shoot over lengthier ranges considering the reticle measurements represent different increments which can vary with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of glass are useful for:
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who select a clearer optic picture with less area used up by the bigger FFP reticle
About Rifle Optic Magnification
The amount of magnification a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass
A single power rifle scope will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a fixed power scope.
Variable Power Lens Optic Details
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Optics
Here are some advised scope power levels and the distances where they can be successfully used. Bear in mind that higher magnification scopes and optics will not be as efficient as lower powered glass since excessive magnification can be a bad thing. The same goes for extended ranges where the shooter needs enough power to see precisely where to properly aim the rifle.
Rifle Scope Lens Covering
All modern rifle scope and optic lenses are covered. Lens covering can be an essential aspect of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use different processes, polarizations, aspects, and chemicals to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Optics
Various optic lenses can also have various finishes used to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope company and the amount you spent on it. Both are indicators of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Rifle Optic Lens Anti-water Covering
Water on a scope lens does not improve maintaining a clear sight picture through an optic in any way. Lots of 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 fine example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Rifle Optics on Long Guns
Installing solutions for scopes are available in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release variations which use toss levers which allow rifle operators to quickly install and remove the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
Normal, clamp design 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 are created for long range precision shooting. This type of scope install is excellent for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. A wide range of scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These types of mounts are useful and handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are utilized in between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Info on Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your pricey optic by resulting in fogging and generating residue within the scope tube. Most scopes prevent wetness from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are worried about the optic still working if it falls overboard and you can still recover the rifle.
Info on Rifle Scope Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less affected by climate changes and pressure distinctions from the outdoor environment which may potentially permit water vapor to permeate 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.
