What You Need to Know About Scopes
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They do this through zoom by making use of a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account various ecological elements like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle optics have about 11 parts which are arranged inside and on the exterior of the optic. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. See all eleven parts of a scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the optimal type of rifle glass depends on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to remain at the very same dimensions in connection with the level of zoom being used. The effect is that the reticle dimensions alter based on the magnification used to shoot over greater ranges considering the reticle markings present distinct increments which vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These kinds of scopes are useful for:
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who choose a clearer optic picture without room taken up by the bigger FFP reticle
Zoom for Optics
The amount of magnification a scope provides is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Scopes
A single power rifle optic or scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate because it is fixed.
Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the magnification level in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adaptation is accomplished by working with the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Optic Power Level and Range Correlation
Here are some recommended scope power settings and the ranges where they could be efficiently used. Highly magnified glass will not be as effective as lower magnification rifle scope glass considering too much magnification can be a bad thing. The exact same concept goes for extended ranges where the shooter needs to have increased power to see where to best aim the rifle at the target.
Lens Finishing for Rifle Glass
All contemporary rifle scope and optic lenses are layered. Lens coating is a vital element of a rifle’s setup when considering high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coverings which use different methods, chemicals, polarizations, and aspects to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Glass
Different optic lenses can likewise have different coverings used to them. All lenses generally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Info on Anti-water Finishing
Water on an optic’s lens does not help with keeping a clear sight picture through a scope in any way. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Scopes on Long Guns
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use toss levers which allow rifle operators to quickly install and dismount the scopes.
Hex Key Rifle Scope Ring Mounts
Standard, clamp-on type mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use two separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This type of scope mount is effective for rifles which need to have a long lasting, unfailing mount which will not move no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted scope system on a reach out and touch someone scouting or tournament rifle which will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to prevent the hex screws from wiggling out after they are installed securely in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining accuracy. These kinds of mounts are useful and convenient for rifles which are transferred a lot, to take off the scope from the rifle for protection, or for optics which are employed between a number of rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Info on Rifle 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 creating residue inside of the scope tube. A lot of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another component of preventing the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less influenced by temperature changes and pressure distinctions from the outside environment which could potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
