What You Need to Know About Scopes
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adapted to take into account many natural elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around 11 parts which are located internally and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other parts. Learn about the eleven parts of rifle glass.
About Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who choose a clearer optic sight picture without space taken up by the larger size FFP reticle
Zoom for Optics
The measure of scope magnification you need on your glass is based on the kind of shooting you desire to do. Pretty much every style of rifle optic delivers some level of zoom. The volume of magnification a scope provides is identified by the size, density, and curvatures of the lenses within the rifle scope. The magnification of the optic is the “power” of the glass. This denotes what the shooter is observing through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Single Power Lens Glass Info
A single power rifle optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not fluctuate given that it is fixed.
Adjustable Power Lens Glass Facts
Variable power rifle scopes can be tweaked between magnified levels. The power change is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Glass Power and Ranges
Here are some advised scope power settings and the distances where they could be effectively used. Always remember that higher power scopes will not be as efficient as lower powered optics due to the fact that too much magnification can be a bad thing. The exact same concept relates to longer distances where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Info on Optic Lens Finish
All modern-day rifle scope and optic lenses are layered. There are various types and qualities of finishes. Lens finish can be a crucial element of a rifle’s setup when considering high end rifle optics and scope systems. The glass lenses are one of the most vital parts of the scope given that they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens surface area and also assists with anti glare capabilities from excess sunlight and color perception.
HD Versus ED Lenses
Some rifle glass suppliers even use “HD” or high-definition lens finishes which use various procedures, aspects, rare earth compounds, and polarizations to extract separate color ranges and viewable definition through lenses. This high-definition coating is commonly used with greater density lens glass which drops light’s potential to refract through the lens glass. Some scope producers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around items with hard shapes as light hits the object from specific angles.
Single Covering Versus Multi-Coating
Various scope lenses can also have different finishes applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in numerous kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
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 lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and just how much you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Rifle Scope Lens Coating
Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic covering.
Alternatives for Installing Rifle Scopes on Firearms
Installing options for scopes are available in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use toss levers which allow rifle operators to rapidly mount and remove the glass.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This kind of scope mount is very good for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should get for a faithful optics system on a far away scouting or interdiction long gun which will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to protect against the hex screws from wiggling out after they are mounted firmly in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever 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. Several scopes can also be switched out if they all use a similar style mount. These types of mounts are handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can ruin a day of shooting and your expensive optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the optic is less influenced by temperature alterations and pressure variations from the outdoor environment which might potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
