Information About Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target at range. They do this through zoom using a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of different natural considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes and optics have about eleven parts which are found inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other elements. See all eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has decides where the reticle or crosshair lies in relation to the optic’s magnification. It literally indicates the reticle is situated behind or ahead of the magnification lens of the scope. Deciding upon the most effective kind of rifle optic is based on what sort of hunting or shooting you anticipate doing.
First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based on the amount of magnification being used. The result is that the reticle measurements are the same at the magnified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This triggers the reticle to stay at the same dimensions in connection with the quantity of magnification being used. The effect is that the reticle measurements adjust based upon the zoom employed to shoot over lengthier distances due to the fact that the reticle measurements present different increments which vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These types of glass work for:
- Long distance styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture without space used up by the larger size FFP reticle
The quantity of magnification a scope provides is figured out 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.
Info About Single Power Lens Rifle Glass
A single power rifle scope comes with 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 zoom of this type of optic can not fluctuate since it is a fixed power optic.
Info on Adjustable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification levels. It will note the zoom amount in a configuration such as 2-10×32. These numbers mean the magnification of the scope can be set in between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adjustment is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell.
Power and Range
Here are some advised scope powers and the distances where they could be successfully used. Keep in mind that high magnification glass will not be as efficient as lower powered optics since increased magnification can be a bad thing. The same concept applies to extended distances where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Rifle Optic Lens Finishing
All state-of-the-art rifle scope lenses are coated. Lens finish is an essential aspect of a rifle’s setup when purchasing high end rifle optics and scope systems.
HD Versus ED Scope Lens Coatings
Some rifle scope companies also use “HD” or high-definition lense coatings which apply different processes, aspects, compounds, and polarizations to enhance numerous colors and viewable target visibility through lenses. This high-definition finishing is frequently used with more costly, high density lens glass which decreases light’s ability to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around objects with hard edges and shapes as light hits the item from particular angles.
About Single Finish Versus Multi-Coating
Different optic lenses can also have different finishings 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 usually a protective and boosting multi-purpose treatment. This lens treatment can protect 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 layered lens depends upon the scope maker and the amount you spent for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can show that a producer is taking several actions to combat different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally doesn’t necessarily imply the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the manufacturer’s lens treatment techniques and the quality of glass used in developing the rifle glass.
Optic Lens Hydrophobic Finish
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Rifle Optic Installation Choices
Installing solutions for scopes can be found in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use throw levers which enable rifle operators to quickly mount and dismount the scopes.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two detached rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are developed for long distance precision shooting. This form of scope mount is excellent for rifles which need a resilient, unfailing mount which will not move despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a faithful scope setup on a far away scouting or hard target interdiction firearm that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to prevent the hex screws from backing out after they are installed securely in position. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Rifle 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. If they all use a similar design mount, multiple scopes can often be swapped on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These kinds of mounts are useful and beneficial for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized 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
Info Around Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. Most scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another component of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by temp shifts and pressure distinctions from the outdoor environment which could potentially permit water vapor to seep 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.
