Information About Glass
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be dialed in to take into account various natural elements like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes have about eleven parts which are arranged internally and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located in connection with the optic’s zoom. It actually means the reticle is situated behind or before the magnification lens of the scope. Selecting the most reliable sort of rifle scope is dependent on what form of shooting or hunting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to remain at the same dimensions in relation to the volume of magnification being used. The final result is that the reticle dimensions evolve based upon the magnification chosen to shoot over greater ranges since the markings represent various increments which can vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular sorts of scopes work for:
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who desire a clearer optic sight picture with less room taken up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Magnification
The amount of scope zoom you require depends on the style of shooting you wish to do. Nearly every kind of rifle optic delivers some amount of zoom. The volume of magnification a scope provides is established by the dimension, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the optic is the “power” of the opic. This suggests what the shooter is aiming at through the scope is magnified times the power element of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust because it is a set power scope.
About Adjustable Power Lens Optics
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will list the magnification amount in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be changed between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adaptation is achieved by employing the power ring component of the scope near the rear of the scope by the eye bell.
Scope Power Level and Range Correlation
Here are some recommended scope powers and the distances where they may be effectively used. Consider that higher magnification optics and scopes will not be as effective as lower magnification level optics and scopes because excessive magnification can be a negative thing in certain situations. The exact same idea applies to longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.
Lens Finish for Optics
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of coatings. When shopping for high end rifle scope devices, Lens covering can be a crucial component of defining the capability of the rifle. The lenses are one of the most critical pieces of the glass due to the fact that 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 area and also assists with anti glare capabilities from excess sunlight and color presence.
Info on Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens coverings which use different techniques, polarizations, chemicals, and aspects to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single layered 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 minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope developer and the amount you spent for it. Both the make and cost are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Rifle Optic Lens Hydrophobic Finish
Water on an optic’s lens doesn’t improve preserving a clear sight picture through an optic whatsoever. Lots of top of the line or premium scope producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface of the Steiner scope lens so the water particles 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.
Rifle Optic Mounting Choices
Installing solutions for scopes are available in a few options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use toss levers which permit rifle shooters to quickly install and dismount the scopes.
Hex Key Scope Rings
Basic, clamp-on design mounting scope rings use hex head screws to install to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use two detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is ideal for rifle systems which require a resilient, hard use mount which will not move regardless of just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a specialized optics setup on a reach out and touch someone scouting or competition firearm which will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely 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 retaining accuracy. These types of mounts are useful and practical for rifles which are moved a lot, to remove the scope glass from the rifle for protection, or for sight systems which are adopted in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It generally costs around $250 USD
Details on Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day of shooting and your costly optic by triggering fogging and making residue within the scope tube. Many scopes protect against moisture from going into the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for conventional use rifles, unless you intend on taking your rifle sailing and are concerned about the scope still working if it goes overboard and you can still retrieve the rifle.
Details on Rifle Glass Tube Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the glass is less altered by condition shifts and pressure distinctions from the outside environment which might possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
