What You Need to Know About Glass
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adjusted for consideration of varied environmental factors like wind and elevation to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about eleven parts which are arranged within and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has decides where the reticle or crosshair lies in connection with the scopes magnifying adjustments. It actually indicates the reticle is situated behind or in front of the magnification lens of the optic. Looking for the most effective kind of rifle optic depends upon what style of shooting or hunting you plan on doing.
About First Focal Plane Optics
First focal plane glass (FFP) feature the reticle ahead of the zoom lens. This causes the reticle to increase in size based upon the amount 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 range. As an example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who understand their target “hold over” and also “lead” correlations for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane glass (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to stay at the same dimensions in relation to the volume of zoom being used. The effect is that the reticle measurements evolve based on the zoom applied to shoot over lengthier distances given that the reticle measurements represent distinct increments which fluctuate with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular sorts of scopes are handy for:
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture without area taken up by the larger size FFP reticle
Ins and Outs of Rifle Scope Zoom
The amount of magnification a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optics
A single power rifle scope uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a fixed power optic.
Adjustable Power Lens Glass Details
Variable power rifle scopes use variable power levels. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some advised scope power levels and the ranges where they can be effectively used. Consider that higher power optics will not be as practical as lower magnification level glass because too much zoom can be a detractor. The same relates to longer ranges where the shooter needs increased power to see precisely where to best aim the rifle.
Details on Rifle Optic Lens Coatings
All modern rifle optic and scope lenses are coated. There are different types and qualities of lens finishings. Lens finish is an important aspect of a rifle’s setup when considering luxury rifle optics and targeting systems. The lenses are among the most key components of the glass as they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses protects the lens exterior and assists with anti glare from excess natural light and color recognition.
About Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different techniques, chemicals, aspects, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Glass
Different optic lenses can even have various coatings applied to them. All lenses typically have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in numerous types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect 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 coated lens depends on the scope manufacturer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can show that a maker is taking numerous actions to combat different environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily imply the multi-coated lens will perform better than a single covered lens. Being “much better” depends upon the manufacturer’s lens treatment innovation and the quality of materials used in creating the rifle scope.
Glass Lens Hydrophobic Finishing
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Choices for Mounting Rifle Glass on Firearms
Mounting options for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically can be found in quick release versions which use throw levers which allow rifle operators to rapidly mount and remove the glass.
Hex Key Scope Ring Mounting Solutions
Basic, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These types of scope mounts use two individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for far away precision shooting. This kind of scope mount is good for rifles which require a long lasting, hard use mount which will not change regardless of how much the scope is moved or jarring the rifle takes. These are the style of mounts you want for a dedicated optics system on a reach out and touch someone hunting or tournament firearm that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to protect against the hex screw threads from backing out after they are installed firmly in position. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can destroy a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Info Around Optic Tube Gas Purging
Another component of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less impacted by temperature level shifts and pressure distinctions from the external 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 decent rifle scope to look for.
