What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom using a set of lenses inside the scope. The scope’s positioning can be adapted to take into account separate natural things like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes and optics have about eleven parts which are located within and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the finest type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Glass Info
First focal plane optics (FFP) feature the reticle ahead of the magnifying lens. This causes the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. For example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who understand their aim point “hold over” and also “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle behind the zoom lens. This triggers the reticle to stay at the exact same size relative to the level of zoom being used. The effect is that the reticle measurements shift based upon the zoom applied to shoot over longer distances considering that the reticle measurements present various increments which differ with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These types of optics are convenient for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture without area taken up by the enlarged FFP reticle
Details on Glass Zoom
The amount of zoom a scope supplies is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Single Power Lens Scopes
A single power rifle optic comes with 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 fluctuate given that it is a fixed power scope.
Variable Power Lens Glass Details
Variable power rifle scopes use variable power levels. The power modification is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some recommended scope power levels and the distances where they may be successfully used. Consider that higher power glass will not be as practical as lower powered scope and optics due to the fact that too much zoom can be a bad thing. The same idea applies to longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.
Rifle Glass Lens Finishing
All contemporary rifle optic lenses are layered. There are different types and qualities of coverings. When looking at high end rifle targeting systems, Lens finishing can be a vital element of a rifle. The lenses are among the most crucial pieces of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses safeguards the lens exterior and even assists with anti glare from excess light and color recognition.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coverings which use different processes, chemicals, aspects, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Covering Versus Multi-Coating
Various scope lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finish put on it so that it will be optimally functional in lots of 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 generally a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope company and how much money you spent on it. Both are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
About Anti-water Coating
Water on an optical lens doesn’t support retaining a clear sight picture through a scope whatsoever. Numerous top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface area of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Optics on Long Guns
Mounting approaches for scopes come in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release versions which use manual levers which allow rifle shooters to rapidly install and dismount the optics.
Hex Key Scope Rings
Basic, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use double independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This kind of scope mount is exceptional for rifle systems which are in need of a durable, unfailing mount which will not move no matter just how much the scope is moved or abuse the rifle takes. These are the style of mounts you should have for a dedicated optics system on a far away hunting or hard target interdiction long gun which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to prevent the hex screw threads from backing out after they are installed firmly in place. An example of these rings are the 30mm type from the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient for long guns 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 multiple rifles.
Details on Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Details on Rifle Glass Tube Gas Purging
Another element of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less influenced by temperature shifts and pressure variations from the external environment which might potentially allow water vapor to seep 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.
