Rifle Glass Facts
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a set of lenses inside the scope. The scope’s alignment can be adjusted to account for various natural aspects 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 upon 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. Most modern-day rifle optics have around 11 parts which are arranged inside and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other components. See all eleven parts of an optic.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has decides where the reticle or crosshair is located relative to the optic’s zoom. It actually indicates the reticle is behind or in front of the magnification lens of the scope. Selecting the very best type of rifle glass is dependent on what form of hunting or shooting you anticipate doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who understand their aim point “hold over” and also “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who want a clearer optic picture with less area used up by the larger sized FFP reticle
Rifle Glass Zoom
The level of scope magnification you need on your glass depends on the sort of shooting you desire to do. Practically every type of rifle optic delivers some amount of magnification. The amount of zoom a scope offers is established by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the glass. This indicates what the shooter is checking out through the scope is amplified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Glass Details
A single power rifle optic 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 type of scope can not adjust since it is a fixed power optic.
Info on Variable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified levels. The power adjustment is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some advised scope powers and the distances where they may be successfully used. Highly magnified rifle scope glass will not be as effective as lower magnification level optics considering too much magnification can be a bad thing. The exact same concept applies to longer ranges where the shooter needs increased power to see where to best aim the rifle at the target.
Details on Scope Lens Finishing
All contemporary rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass lens finishings. When thinking about high end rifle optical setups, Lens covering can be a critical component of defining the capability of the rifle. The lenses are one of the most crucial parts of the scope given that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens exterior and assists with anti glare from excess direct sunlight and color perception.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use different processes, chemicals, aspects, and polarizations to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Optic Lens Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different finishings used to them. All lenses typically have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic.
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 layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly 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 technology and the quality of products used in building the rifle scope.
About Hydrophobic Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic coating which is water repellent.
Options for Installing Rifle Optics on Firearms
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use toss levers which permit rifle operators to rapidly install and remove the scopes.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, clamp design 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 range precision shooting. This type of scope install is excellent for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving accuracy. These kinds of mounts are useful and practical for shooting platforms which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are adopted in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Many scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another part of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less altered by temperature level shifts and pressure differences from the outdoor environment which could potentially allow 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.
