What You Need to Know About Rifle Optics
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a range. They do this through zoom by using a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account numerous environmental considerations like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters 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. Most modern-day rifle scopes and optics have about 11 parts which are found inside and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle glass is based on what type of shooting you plan on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” plus “lead” equations for their rifles
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind 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.
- Long distance forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who want a clearer optic picture without area used up by the bigger FFP reticle
Details on Rifle Scope Zoom
The quantity of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Single Power Lens Optics
A single power rifle optic and scope uses a magnification number designator like 4×32. This suggests 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 considering that it is a fixed power scope.
Adjustable Power Lens Optic Info
Variable power rifle scopes use variable power levels. The power adjustment is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Optics
Here are some recommended scope powers and the distances where they may be successfully used. High power rifle scope glass will not be as efficient as lower powered rifle scope glass considering too much zoom can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs to have adequate power to see where to best aim the rifle.
Lens Coating for Glass
All contemporary rifle scope and optic lenses are layered. There are various types and qualities of glass finishes. When researching high end rifle scope setups, Lens covering can be an important aspect of defining the rifle’s capability. The glass lenses are among the most important parts of the glass as 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 exterior and also helps with anti glare from refracted natural light and color perception.
Details on Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coverings which use different procedures, polarizations, chemicals, and components to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Rifle Optic Lens Finishing Versus Multi-Coating
Various scope lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a covering applied to it so that the lens will be efficiently functional in many kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing 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 upon the scope developer and how much you paid for it. Both the make and cost are indicators of the lens quality.
Some scope manufacturers also 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 products used in constructing the rifle scope.
Anti-water Lens Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Optic Mounting Options
Mounting solutions for scopes are available in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the scopes.
Hex Key Rifle Scope Rings
Standard, clamp type mounting optic rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double individual rings to support the optic, and are made from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This type of scope mount is great for rifles which need to have a durable, rock solid mount which will not shift no matter how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a devoted optics system on a reach out and touch someone scouting or hard target interdiction long gun which will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used to keep 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 brand. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These kinds of mounts are useful and practical for rifles which are hauled around a lot, to remove the scope glass from the rifle for protection, or for sight systems which are employed between several rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less altered by temperature changes and pressure variations from the outdoor environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
