Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a series of lenses within the scope. The scope’s positioning can be adjusted to take into account separate ecological things like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. A lot of modern rifle optics have about 11 parts which are arranged internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. Learn about the eleven parts of glass.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the perfect type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who know their target “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane glass (SFP) come with the reticle behind the zoom lens. This induces the reticle to remain at the exact same dimensions in relation to the volume of magnification being used. The outcome is that the reticle measurements adjust based upon the magnification chosen to shoot over longer ranges because the markings represent various increments which differ with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of glass are convenient for:
- Long distance types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who want a clearer optic sight picture with less area taken up by the larger size FFP reticle
Magnification for Rifle Scopes
The measure of scope zoom you need on your scope depends upon the kind of shooting you want to do. Virtually every kind of rifle optic supplies some degree of zoom. The level of magnification a scope offers is determined by the dimension, thickness, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the scope. This means what the shooter is looking at through the scope is amplified times the power factor of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic or scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust since it is set from the factory.
About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified levels. The power change is handled using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power levels and the ranges where they can be effectively used. High power optics will not be as beneficial as lower powered glass because too much magnification can be a bad thing. The same idea goes for longer ranges where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Rifle Optic Lens Finishing
All modern-day rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. Lens finish can be an essential element of a rifle’s setup when thinking of high end rifle optics and scope systems. The glass lenses are among the most essential parts of the scope given that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface as well as improves anti glare from excess direct sunlight and color discernibility.
Info on Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishings which use various processes, polarizations, components, and chemicals to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Info on Single Covering Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses typically have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finish placed on it so that it will be efficiently functional in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Coating
Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Rifle Scope Installing Options
Mounting approaches for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the scope 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 manual levers which permit rifle operators to rapidly install and remove the glass.
Hex Key Scope Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount 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 are created for long range precision shooting. This type of scope install is great for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between several rifles or are situationally focused.
What to Know About Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another component of preventing the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the scope is less impacted by temperature level shifts and pressure variations from the outside environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
