Rifle Optic Information
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a range. They accomplish this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of numerous ecological things like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle optics have about 11 parts which are located within and outside of the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. See all eleven parts of a scope.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who know their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter distances and ranges
- Shooters who choose a clearer optic sight picture with less space taken up by the bigger FFP reticle
Rifle Glass Magnification
The amount of scope magnification you require depends on the form of shooting you choose to do. Nearly every type of rifle scope provides some degree of magnification. The level of zoom a scope offers is established by the dimension, thickness, and curves of the lenses within the rifle scope. The magnification level of the optic is the “power” of the opic. This signifies what the shooter is looking at through the scope is magnified times the power factor of what can normally be seen by human eyes.
Single Power Lens Rifle Scope Facts
A single power rifle optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate given that it is a set power scope.
Info on Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will list the magnification level in a format like 2-10×32. These numbers indicate the zoom of the scope can be adjusted between 2x and 10x power. This always involves the powers in-between 2 and 10. The power modification 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 Correlation of Rifle Optics
Here are some recommended scope powers and the distances where they may be successfully used. High power optics will not be as beneficial as lower magnification level glass because too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs to have adequate power to see precisely where to properly aim the rifle.
Details on Lens Covering
All modern rifle optic and scope lenses are layered. There are different types and qualities of glass finishes. Lens finishing is an essential element of a rifle’s setup when thinking about high end rifle optics and targeting equipment. The lenses are one of the most essential components of the optic as they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens surface area and even assists with anti glare from refracted natural light and color recognition.
Details on Lens Coatings – HD Versus ED
Some glass makers even use “HD” or high-def lense coverings that use various procedures, components, chemical substances, and polarizations to enhance separate color ranges and viewable target visibility through lenses. This HD finishing is normally used with more costly high density lens glass which decreases light’s chance to refract through the lens glass. Some scope vendors use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable around things with hard edges and shapes as light hits the item from particular angles.
Single Scope Lens Coating Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses usually have at least some type of treatment or covering applied 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 preserve the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope producer and how much you spent on it. Both the make and cost are signs of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” covered. This indicates the lens has had several treatments applied to the surfaces. If a lens receives several treatments, it can show that a manufacturer is taking several actions to fight various environmental factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally does not necessarily suggest the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the producer’s lens treatment technology and the quality of components used in developing the rifle optic.
Anti-water Finish for Scopes
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic anti-water finishing.
Options for Mounting Rifle Scopes on Long Guns
Mounting solutions for scopes come in a few options. There are the basic 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 can be found in quick release versions which use throw levers which enable rifle shooters to rapidly mount and dismount the scope.
Hex Key Optic Ring Mounts
Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These kinds of scope mounts use double separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This kind of scope mount is great for rifles which need a long lasting, unfailing mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a faithful scope system on a reach out and touch someone hunting or interdiction firearm which will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are mounted tightly in place. An example of these rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping accuracy. These types of mounts come in beneficial for rifles which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for scopes which are adopted in between a number of 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 Scope Tubes
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope 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 area is currently taken up by the gas, the optic is less altered by climate alterations and pressure differences from the external environment which could 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.
