About Rifle Glass
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s alignment can be adapted to account for varied ecological factors like wind and elevation increases or decreases to account 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 scope as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have about 11 parts which are arranged within and outside of the scope. These optic pieces include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It actually suggests the reticle is located behind or in front of the magnifying lens of the scope. Picking out the most desired form of rifle glass depends on what form of shooting you anticipate doing.
About First Focal Plane Scopes
First focal plane glass (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. 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 are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle behind the magnification lens. This causes the reticle to stay at the same overall size relative to the level of magnification being used. The final result is that the reticle dimensions adapt based upon the magnification employed to shoot over longer ranges given that the reticle measurements represent distinct increments which fluctuate 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 reticle measurement. These sorts of glass work for:
- Far away types of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who select a clearer optic sight picture without space used up by the enlarged FFP reticle
Zoom for Optics
The level of scope magnification you need depends on the sort of shooting you plan to do. Practically every style of rifle optic provides some amount of magnification. The quantity of magnification a scope offers is determined by the diameter, thickness, and curves of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the opic. This means what the shooter is checking out through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Glass Details
A single power rifle optic or scope will have a magnification 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 kind of scope can not fluctuate given that it is a set power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the magnification amount in a format like 2-10×32. These numbers mean the magnification of the scope can be adjusted between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adaptation is accomplished using the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Glass
Here are some recommended scope power settings and the distances where they can be efficiently used. Consider that higher power optics will not be as efficient as lower powered optics and scopes because excessive zoom can be a detractor. The same idea applies to extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle at the target.
About Optic Lens Finish
All top teir rifle scope lenses are layered. Lens finish can be an important element of a rifle’s setup when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use different methods, polarizations, elements, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can likewise have different finishes used to them. All lenses typically have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single covered 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 beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope manufacturer and the amount you spent on it. Both are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can prove that a maker is taking several actions to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also doesn’t necessarily suggest the multi-coated lens will perform much better than a single layered lens. Being “much better” is dependent on the producer’s lens treatment innovation and the quality of products used in building the rifle optic.
About Hydrophobic Finish
Water on a scope lens doesn’t improve maintaining a clear sight picture through a scope in any way. Lots of top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Glass Mounting Choices
Installing approaches for scopes are available in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release versions which use manual levers which enable rifle shooters to quickly mount and remove the scopes.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is fine for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. Multiple scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving accuracy. These types of mounts are useful and convenient for rifles which are moved a lot, to remove the optic from the rifle for protection, or for optics which are used 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
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day on the range and your highly-priced optic by inducing fogging and generating residue within the scope’s tube. Many scopes prevent wetness from going into the optical tube with a series of sealing O-rings which are waterproof. Normally, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness avoidance for standard use rifles, unless you anticipate taking your rifle on a boat and are concerned about the optic still performing if it falls overboard and you can still find the rifle.
Info on Rifle Glass Tube Gas Purging
Another part of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less impacted by temp alterations and pressure differences from the outdoor environment which might potentially enable 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 seek out.
