About Rifle Scopes
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by utilizing a series of lenses within the scope. The scope’s positioning can be dialed in to account for various ecological considerations like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around 11 parts which are found within and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other parts. See all eleven parts of scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the perfect type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who like a clearer optic sight picture with less area used up by the larger size FFP reticle
About Rifle Scope Magnification
The measure of scope zoom you need on your optic depends on the form of shooting you wish to do. Practically every style of rifle glass supplies some amount of zoom. The volume of magnification a scope offers is established by the size, density, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the opic. This denotes what the shooter is aiming at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Info on Fixed Power Lens Rifle Scopes
A single power rifle scope will have 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 scope can not fluctuate since it is a set power scope.
About Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some suggested scope power levels and the distances where they can be efficiently used. Keep in mind that high magnification optics and scopes will not be as effective as lower magnification level glass due to the fact that increased zoom can be a bad thing. The exact same idea applies to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Info on Lens Coverings
All present day rifle scope and optic lenses are covered. Lens covering can be a crucial aspect of a rifle’s setup when considering high end rifle optics and scope equipment.
Details on Glass Lens Coatings – HD Versus ED
Some glass manufacturers will also use “HD” or high-definition glass finishes that take advantage of various processes, rare earth compounds, elements, and polarizations to enhance numerous color ranges and viewable target visibility through the lens. This high-def covering is often used with increased density lens glass which decreases light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be noticeable around things with defined outlines as light hits the object from certain angles.
Rifle Optic Lens Single Finish Versus Multi-Coating
Different scope lenses can even have various finishings applied to them. All lenses usually have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has had multiple treatments applied to the surfaces. If a lens gets several treatments, it can prove that a manufacturer is taking several steps to combat various environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not necessarily imply the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the manufacturer’s lens treatment techniques and the quality of components used in building the rifle scope.
Anti-water Coating for Rifle Optics
Water on a scope’s lens does not support maintaining a clear sight picture through an optic in any way. Many top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Glass Mounting Options
Mounting approaches for scopes come in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use throw levers which enable rifle operators to rapidly mount and dismount the scopes.
Hex Key Glass Ring Mounts
Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This kind of scope mount is ideal for rifles which need to have a durable, rock solid mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the style of mounts you really want to have for a faithful scope system on a long distance hunting or competitors long gun that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
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. Multiple scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day on the range and your costly optic by causing fogging and generating residue within the scope’s tube. Many scopes prevent humidity from getting in the scope tube with a series of sealing O-rings which are water resistant. Generally, these 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 sufficient wetness prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the scope still performing if it is submerged in water and you can still retrieve the gun.
Info Around Optic Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less impacted by climate shifts and pressure variations from the external environment which could 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 good rifle scope to look for.
