What You Need to Know About Scopes
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by using a series of lenses within the scope. The scope’s positioning can be dialed in to account for numerous ecological things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. A lot of modern rifle scopes and optics have around eleven parts which are found within and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. See all eleven parts of an optic.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has identifies where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It simply indicates the reticle is behind or before the magnification lens of the scope. Picking out the most suitable kind of rifle scope is based on what sort of hunting or shooting you intend on doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who prefer a clearer optic sight picture with less room taken up by the bigger FFP reticle
Magnification for Rifle Glass
The quantity of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info on Single Power Lens Glass
A single power rifle optic will have a zoom 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 kind of scope can not fluctuate since it is a set power scope.
Variable Power Lens Rifle Optic Info
Variable power rifle scopes use enhanced power. The power modification is performed 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 Correlation of Scopes
Here are some suggested scope power settings and the ranges where they can be successfully used. High power rifle scope glass will not be as efficient as lower powered optics considering too much magnification can be a bad thing. The same concept relates to extended ranges where the shooter needs to have sufficient power to see where to best aim the rifle.
Rifle Scope Lens Finish
All contemporary rifle scope and optic lenses are coated. Lens finishing can be an essential aspect of a shooting system when thinking about 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 various processes, polarizations, chemicals, and components to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Scopes
Different optic lenses can also have different coatings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing 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 manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on an optical lens doesn’t support preserving a clear sight picture through an optic whatsoever. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Choices for Installing Glass on Firearms
Mounting approaches for scopes can be found in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use toss levers which permit rifle shooters to quickly install and remove the optics.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use two detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is effective for rifle systems which need to have a long lasting, hard use mount which will not change despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized optics system on a reach out and touch someone scouting or tournament long gun which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screw threads from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining the original sighting settings. These kinds of mounts come in beneficial for shooting platforms which are hauled around a lot, to remove the scope from the rifle for protection, or for sight systems which are adopted in between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Details on Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. The majority of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less impacted by temp shifts and pressure differences from the external environment which may possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
