Scope Info
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification using a series of lenses within the scope. The scope’s positioning can be adapted for consideration of various environmental considerations like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes have about eleven parts which are arranged within and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. See all eleven parts of a scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the optimal type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who understand their target “hold over” and also “lead” correlations for their firearms
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Second Focal Plane Optic Details
Second focal plane scopes (SFP) feature the reticle behind the magnification 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.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who would like a clearer optic picture with less space used up by the enlarged FFP reticle
Zoom for Rifle Scopes
The extent of scope zoom you need on your optic depends on the form of shooting you desire to do. Just about every kind of rifle glass provides some amount of magnification. The amount of zoom a scope offers is determined by the diameter, density, and curvatures of the lenses within the rifle optic. The magnification level of the optic is the “power” of the opic. This denotes what the shooter is aiming at through the scope is amplified times the power element of what can generally be seen by human eyes.
Single Power Lens Rifle Optic Details
A single power rifle optic or scope uses a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is fixed.
Variable Power Lens Scope Facts
Variable power rifle scopes can be tweaked between magnified levels. The power change is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some advised scope power settings and the distances where they may be efficiently used. Highly magnified optics will not be as useful as lower magnification scopes because too much magnification can be a bad thing. The same applies to extended distances where the shooter needs to have adequate power to see where to properly aim the rifle.
Glass Lens Finish
All modern rifle scope lenses are layered. There are various types and qualities of coverings. When thinking about luxury rifle targeting systems, Lens covering can be a vital component of defining the rifle’s capability. The lenses are among the most important pieces of the glass since they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface and also helps with anti glare capabilities from refracted sunlight and color discernibility.
ED Versus HD Rifle Scopes
Some scope producers likewise use “HD” or high-definition lens coatings which use different methods, chemicals, elements, and polarizations to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Scope Lens Single Finish Versus Multi-Coating
Various optic lenses can even have different coatings applied to them. All lenses generally have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in numerous types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and how much you paid for it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finishing
Water on a scope lens does not assist with maintaining a clear sight picture through a scope in any way. Numerous top of the line and high-end optic producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use manual levers which allow rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope install is great for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a comparable style mount, multiple scopes can also be switched out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts are useful and convenient for rifles which are shipped a lot, to take off the optic from the rifle for protection, or for optics which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle glass can ruin a day on the range and your expensive optic by inducing fogging and developing residue within the scope tube. Most optics prevent wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard a watercraft and are concerned about the optic still functioning if it goes over the side and you can still rescue the firearm.
Gas Purged Glass Tubes
Another element of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less impacted by condition changes and pressure variations from the outside environment which could potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
