Glass Info
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 magnification by utilizing a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of separate environmental elements like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle optics have around 11 parts which are found internally and outside of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane an optic has identifies where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It simply means the reticle is located behind or ahead of the magnifying lens of the scope. Picking the most suitable form of rifle glass is dependent on what type of shooting you plan on doing.
About First Focal Plane Scopes
First focal plane scopes (FFP) come with the reticle ahead of the magnification lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their aim point “hold over” and also “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Glass Info
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This causes the reticle to remain at the exact same size relative to the volume of zoom being used. The result is that the reticle dimensions alter based upon the magnification applied to shoot over lengthier distances considering that the reticle measurements present different increments which can vary with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These kinds of optics are useful for:
- Long distance forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who want a clearer optic picture with less space used up by the larger size FFP reticle
Optic Zoom
The quantity of zoom a scope supplies is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Scope Info
A single power rifle scope will have a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is set from the factory.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification amount in a format like 2-10×32. These numbers mean the magnification of the scope could be adjusted in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power manipulation is achieved by employing the power ring component of the scope near the back of the scope by the eye bell piece.
The Power and Range of Scopes
Here are some advised scope power settings and the distances where they can be efficiently used. High power scopes will not be as beneficial as lower powered glass considering that too much magnification can be a negative aspect depending on your shooting distance. The same concept relates to extended ranges where the shooter needs enough power to see precisely where to best aim the rifle.
Info on Optic Lens Coating
All top of the line rifle optic lenses are covered. Lens finish can be a vital element of a rifle’s setup when looking into high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens finishings which use different methods, components, polarizations, and chemicals to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can even have different finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finishing applied to it so that it will be optimally functional in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial 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 makers likewise make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has multiple treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can indicate that a manufacturer is taking several actions to fight different environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally doesn’t necessarily imply the multi-coated lens is better than a single covered lens. Being “better” is dependent on the manufacturer’s lens treatment techniques and the quality of components used in constructing the rifle optic.
Hydrophobic Glass Lens Finish
Water on an optic’s lens doesn’t improve retaining a clear sight picture through a scope in any way. Lots of top of the line and premium 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 treats the exterior of the Steiner optic 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.
Choices for Installing Glass on Firearms
Installing approaches for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally are made in quick release versions which use throw levers which allow rifle operators to rapidly mount and remove the glass.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This kind of scope mount is very good for rifle systems which need a long lasting, rock solid mount which will not shift regardless of just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a faithful optics setup on a reach out and touch someone scouting or hard target interdiction firearm that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. A wide range of scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 while maintaining the original sighting settings. These types of mounts come in convenient for shooting platforms which are shipped a lot, to take off the scope from the rifle for protection, or for aiming systems which are adopted between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can mess up a day on the range and your pricey optic by triggering fogging and producing residue inside of the scope’s tube. Many optics protect against humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for standard use rifles, unless you anticipate taking your rifle on your motorboat and are concerned about the scope still working if it goes overboard and you can still salvage the firearm.
Rifle Optic Gas Purging
Another component of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the scope is less altered by temperature changes and pressure variations from the outdoor environment which might potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
