What You Need to Know About Rifle Scopes
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnifying the target using a series of lenses inside the scope. The scope’s alignment can be adapted to take into account many environmental considerations like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have around eleven parts which are located internally and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair lies in connection with the scopes zoom. It actually means the reticle is located behind or in front of the magnification lens of the scope. Looking for the best type of rifle glass is based upon what type of shooting or hunting you anticipate doing.
First Focal Plane Scope Facts
First focal plane optics (FFP) include the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who understand their aim point “hold over” and also “lead” correlations for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This induces the reticle to stay at the exact same size in relation to the quantity of zoom being used. The end result is that the reticle dimensions evolve based upon the magnification used to shoot over greater ranges given that the markings present various increments which change with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These types of optics are convenient for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who would like a clearer optic picture with less area taken up by the enlarged FFP reticle
Details on Rifle Optic Magnification
The amount of zoom a scope supplies is identified 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.
Info About Fixed Power Lens Glass
A single power rifle optic uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change because it is a fixed power optic.
Variable Power Lens Scopes
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 Correlations
Here are some advised scope power levels and the distances where they may be efficiently used. High power glass will not be as beneficial as lower powered optics due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to extended ranges where the shooter needs to have adequate power to see where to best aim the rifle at the target.
Rifle Optic Lens Finishing
All contemporary rifle scope and optic lenses are coated. There are various types and qualities of lens finishings. When researching high end rifle targeting setups, Lens finishing can be an essential component of defining the rifle’s capability. The lenses are one of the most important parts of the glass considering that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface area as well as improves anti glare from excess sunrays and color visibility.
HD Versus ED Lenses
Some glass suppliers will also use “HD” or high-definition lens finishings which employ various processes, chemicals, polarizations, and elements to extract numerous color ranges and viewable target visibility through lenses. This high-definition finish is normally used with more costly, high density lens glass which drops light’s ability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration may be visible over items with hard outlines as light hits the item from specific angles.
Single Optic Lens Coating Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and the amount you spent for it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” covered. This suggests the lens has numerous treatments applied to the surfaces. If a lens gets several treatments, it can establish that a maker is taking numerous actions to combat different natural factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This additionally does not always suggest the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the manufacturer’s lens treatment solutions and the quality of components used in building the rifle optic.
Hydrophobic Coating for Rifle Scopes
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic coating which is water repellent.
Glass Installing Options
Mounting approaches for scopes can be found in a couple of options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Rifle Optic Rings
Basic, clamp-on style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two independent rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This form of scope mount is good for rifle systems which are in need of a resilient, rock solid mount which will not change regardless of how much the scope is moved or jarring the rifle takes. These are the design of mounts you really want to have for a devoted scope system on a far away hunting or sniper competition firearm which will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from backing out after they are mounted firmly in place. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible design mount. These types of mounts are handy for rifles which are transported a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
What to Know About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Optic Tube Gas Purging
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the optic is less influenced by climate alterations and pressure variations from the external environment which may potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
