Info Rifle Optics
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted for the consideration of numerous natural things like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have about 11 parts which are arranged within and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies relative to the optic’s zoom. It literally suggests the reticle is behind or before the magnifying lens of the optic. Deciding on the most beneficial style of rifle glass is dependent on what style of shooting or hunting you intend on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who prefer a clearer optic picture with less area taken up by the larger sized FFP reticle
Rifle Glass Zoom
The quantity of scope magnification you need on your scope is based on the form of shooting you want to do. Almost every kind of rifle glass provides some degree of magnification. The level of magnification a scope offers is established by the diameter, density, and curvatures of the lens glass inside of the rifle scope. The magnification of the scope is the “power” of the scope. This signifies what the shooter is observing through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Single Power Lens Rifle Glass
A single power rifle scope and optic will have 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 kind of scope can not fluctuate considering that it is a fixed power optic.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified settings. The power change is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some advised scope power settings and the ranges where they can be efficiently used. Highly magnified scopes will not be as effective as lower powered scopes since too much magnification can be a bad thing. The exact same idea goes for longer distances where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Info on Glass Lens Finishing
All contemporary rifle optic lenses are layered. Lens finishing can be a vital element of a shooting system when purchasing high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens coverings which use different procedures, polarizations, chemicals, and components to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can likewise have various finishings used to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing 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 manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can indicate that a producer is taking several actions to combat different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also doesn’t always mean the multi-coated lens will perform better than a single covered lens. Being “better” hinges on the manufacturer’s lens treatment innovation and the quality of glass used in constructing the rifle scope.
Hydrophobic Rifle Optic Lens Coating
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Scope Mounting Choices
Mounting approaches for scopes are available in a few choices. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release variations which use throw levers which permit rifle shooters to quickly install and dismount the optics.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. Several scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping the original sighting settings. These types of mounts are useful and convenient for rifles which are hauled around a lot, to take off the scope glass from the rifle for protection, or for scopes which are employed between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your highly-priced optic by inducing fogging and making residue inside of the scope’s tube. The majority of optics protect against wetness from getting in the optical tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it goes over the side and you can still recover the gun.
Gas Purged Optic Tubes
Another part of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the glass is less affected by temp alterations and pressure differences from the outside environment which may possibly 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.
