Information About Rifle Optics
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses inside the scope. The scope’s alignment can be dialed in for consideration of various natural elements like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have about eleven parts which are found inside and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who have an idea for their target “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the magnification 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 reticle measurement.
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who desire a clearer optic picture without space used up by the enlarged FFP reticle
Ins and Outs of Rifle Scope Zoom
The quantity of zoom a scope offers is identified by the size, 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 Scopes
A single power rifle optic uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change since it is a set power scope.
Variable Power Lens Glass
Variable power rifle scopes use variable power levels. The power change is performed using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power Level and Range Correlation
Here are some recommended scope power levels and the distances where they may be effectively used. Bear in mind that high power scopes will not be as efficient as lower powered optics and scopes since too much magnification can be a bad thing. The exact same idea relates to extended distances where the shooter needs to have enough power to see exactly where to best aim the rifle.
Lens Finishing for Rifle Glass
All contemporary rifle scope lenses are coated. Lens finish is a crucial aspect of a shooting platform when considering high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens finishes which use various processes, elements, polarizations, and chemicals 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.
Rifle Glass Lens Single Covering Versus Multi-Coating
Various scope lenses can also have different coatings applied to them. All lenses normally have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a finish put on it so that it will be efficiently functional in numerous types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less helpful 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 just how much you paid for it. Both are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has had multiple treatments applied to them. If a lens receives several treatments, it can indicate that a maker is taking multiple steps to fight various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always imply the multi-coated lens is much better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment solutions and the quality of glass used in developing the rifle optic.
Hydrophobic Lens Finishing
Water on an optic’s lens does not assist with preserving a clear sight picture through a scope in any way. Lots of top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Options for Installing Rifle Glass on Long Guns
Mounting approaches for scopes can be found in a few options. 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 normally can be found in quick release versions which use manual levers which allow rifle shooters to quickly mount and dismount the scopes.
Hex Key Rifle Optic Ring Mounts
Standard, clamp style 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope install is excellent for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can destroy a day of shooting and your highly-priced optic by inducing fogging and producing residue inside of the scope tube. The majority of optics prevent wetness from going into the optical tube with a series of sealing O-rings which are water resistant. Typically, these water resistant optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the optic still functioning if it goes over the side and you can still recover the gun.
Info Around Rifle Scope Tube Gas Purging
Another element of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less impacted by temp changes and pressure differences from the outdoor environment which could potentially allow 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.
