Scope Info
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target using a series of lenses within the scope. The scope’s alignment can be dialed in to take into account many ecological factors like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes have around eleven parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. See all eleven parts of an optic.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the perfect type of rifle optic is based on what type of shooting you plan on doing.
Info on First Focal Plane Glass
First focal plane glass (FFP) include the reticle ahead of the magnification lens. This triggers the reticle to increase in size based upon the level of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the magnifying lens. This induces the reticle to remain at the exact same overall size in relation to the volume of magnification being used. The effect is that the reticle measurements adapt based on the magnification chosen to shoot over greater distances considering the reticle measurements present distinct increments which differ with the zoom. In the FFP example with the SFP glass, 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:
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who want a clearer optic picture with less space used up by the enlarged FFP reticle
Zoom for Optics
The quantity 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.
Fixed Single Power Lens Rifle Optics
A single power rifle scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate because it is fixed.
Adjustable Power Lens Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power change is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the ranges where they can be effectively used. Consider that high magnification glass will not be as effective as lower magnification level scopes because increased magnification can be a bad thing. The same idea applies to extended distances where the shooter needs enough power to see where to properly aim the rifle at the target.
About Rifle Scope Lens Coating
All contemporary rifle optic and scope lenses are coated. Lens finish can be a crucial aspect of a rifle’s setup when buying high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use different procedures, polarizations, aspects, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can likewise have various coatings used to them. All lenses normally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
This lens treatment can protect 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 covered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
What to Know About Hydrophobic Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering.
Rifle Glass Installation Choices
Installing solutions for scopes are available in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use throw levers which allow rifle operators to rapidly mount and remove the scope.
Hex Key Optic Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope mount is perfect for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Optic 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. Several scopes can even be switched out if they all use a similar design mount. These types of mounts are handy for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles or are situationally focused.
About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your expensive optic by triggering fogging and producing residue inside of the scope tube. Most scopes protect against wetness from going into the scope tube with a series of sealing O-rings which are waterproof. Usually, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness avoidance for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are concerned about the optic still performing if it goes overboard and you can still recover the gun.
Scope Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the optic is less impacted by condition alterations and pressure distinctions from the outside environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
