What You Need to Know About Rifle Optics
Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom by employing a series of lenses within the scope. The scope’s alignment can be adjusted to take into account numerous environmental considerations like wind and elevation decreases to make up 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 via the optic as you align the scope’s crosshair or reticle with the target. The majority of modern rifle scopes have about eleven parts which are arranged inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other components. Learn about the eleven parts of glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle optic depends on what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who select a clearer optic sight picture without space used up by the larger sized FFP reticle
Details on Rifle Glass Zoom
The amount of zoom a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Optics
A single power rifle optic and scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is a fixed power scope.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification amount in a configuration like 2-10×32. These numbers indicate the magnification of the scope could be changed between 2x and 10x power. This also involves the powers in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range of Rifle Glass
Here are some suggested scope power settings and the ranges where they can be efficiently used. High power optics will not be as efficient as lower magnification glass considering too much zoom can be a negative aspect depending on your shooting distance. The exact same concept goes for longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle.
About Glass Lens Finish
All modern rifle optic and scope lenses are coated. There are different types and qualities of finishings. When researching luxury rifle optical units, Lens coating can be a significant aspect of defining the capability of the rifle. The lenses are one of the most crucial components of the scope considering they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface as well as assists with anti glare capabilities from refracted daylight and color exposure.
About Rifle Scope Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens finishes which use various procedures, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
About Single Finish Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope manufacturer and how much you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Optic Lens Anti-water Coating
Water on an optic’s lens doesn’t improve preserving a clear sight picture through an optic at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior surfaces of the Steiner optic lens so the water particles can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Rifle Glass Installation Choices
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Hex Key Rifle Glass Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is wonderful for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even 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 protection, or for scopes which are used in between several rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle glass can ruin a day of shooting and your highly-priced optic by inducing fogging and making residue inside of the scope’s tube. Most optics prevent humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these water resistant optics 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 humidity avoidance for standard use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it goes over the side and you can still find the firearm.
Gas Purged Rifle Scope Tubes
Another part of avoiding the accumulation 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 glass is less altered by climate changes and pressure variations from the outdoor environment which might possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
