What You Need to Know About Optics
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adapted to take into account various environmental things like wind and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have around eleven parts which are found inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Glass Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the level of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their long gun
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This triggers the reticle to stay at the very same size in connection with the quantity of zoom being used. The end result is that the reticle measurements evolve based upon the magnification applied to shoot over longer distances considering the reticle markings present distinct increments which differ with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These types of scopes work for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who would like a clearer optic sight picture without room used up by the bigger FFP reticle
Ins and Outs of Rifle Optic Zoom
The amount of zoom a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust considering that it is set from the factory.
Info on Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power change is accomplished by using 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 recommended scope powers and the distances where they may be successfully used. High power rifle scope glass will not be as efficient as lower powered glass because too much zoom can be a bad thing. The same concept goes for longer ranges where the shooter needs to have sufficient power to see precisely where to properly aim the rifle at the target.
Info on Lens Covering
All contemporary rifle scope lenses are coated. There are different types and qualities of glass lens finishings. Lens finish is a crucial element of a rifle’s setup when looking at luxury rifle optics and scope equipment. The lenses are one of the most key components of the optic considering they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area and helps with anti glare capabilities from refracted direct sunlight and color perception.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens finishings which use different techniques, chemicals, elements, and polarizations to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Glass
Different optic lenses can also have different finishings used to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope maker and the amount you spent for it. Both are indications of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets multiple treatments, it can prove that a producer is taking numerous actions to combat various natural elements like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This also does not necessarily suggest the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the maker’s lens treatment techniques and the quality of products used in creating the rifle glass.
Info on Hydrophobic Finishing
Water on a scope’s lens does not help with maintaining a clear sight picture through a scope whatsoever. Lots of top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface of the Steiner scope lens so the H2O 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.
Alternatives for Mounting Scopes on Firearms
Mounting solutions for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually are made in quick release versions which use manual levers which enable rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Scope Rings
Standard, clamp-on design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of detached rings to support the scope, and are made from 7075 T6 billet aluminum which are developed for far away accuracy shooting. This type of scope mount is effective for rifles which require a long lasting, hard use mount which will not move no matter just how much the scope is moved or jarring the rifle takes. These are the style of mounts you should have for a specialized scope setup on a far away hunting or tournament firearm which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s 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 style made by Vortex Optics. The set typically costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for long guns which are transported a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can spoil a day of shooting and your expensive optic by inducing fogging and producing residue within the scope’s tube. Many scopes prevent humidity from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are concerned about the optic still working if it is submerged in water and you can still salvage the firearm.
What to Know About Rifle Scope Tube Gas Purging
Another component of avoiding the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less impacted by temperature shifts and pressure distinctions from the outdoor environment which could possibly enable 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 seek out.
