Facts About Rifle Optics
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of different ecological things like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes have about eleven parts which are found inside and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other parts. See all eleven parts of an optic.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located in relation to the optic’s zoom. It simply implies the reticle is behind or before the magnification lens of the scope. Looking for the most ideal kind of rifle optic is dependent on what kind of shooting you anticipate doing.
First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle before the magnifying lens. This causes the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane scopes (SFP) include 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 increased time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less space used up by the larger size FFP reticle
Rifle Glass Zoom
The amount of magnification a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Optics
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change since it is set from the factory.
Adjustable Power Lens Rifle Optic Details
Variable power rifle scopes can be tweaked between magnified levels. The power change is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some recommended scope power levels and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification glass considering too much magnification can be a bad thing. The same idea applies to extended distances where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Lens Finishing for Scopes
All contemporary rifle optic and scope lenses are coated. There are various types and qualities of glass lens finishes. Lens coating is an essential element of a rifle’s setup when thinking of luxury rifle optics and targeting units. The glass lenses are one of the most important components of the optic given that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens surface area and assists with anti glare capabilities from excess sunshine and color exposure.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishes which use various processes, elements, polarizations, and chemicals to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Various scope lenses can also have different finishings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finishing put on it so that the lens will be efficiently functional in lots of kinds of environments, degrees of sunshine (full light VS shaded), 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 layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Finish for Rifle Scopes
Water on a lens does not assist with keeping 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 finishing.
Options for Installing Rifle Glass on Firearms
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the optic 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 enable rifle shooters to quickly mount and remove the scope.
Hex Key Rifle Glass 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is excellent for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and practical for shooting platforms which are hauled around a lot, to take off the scope from the rifle for protection, or for scopes which are used between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day on the range and your expensive optic by triggering fogging and making residue within the scope’s tube. Many scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are worried about the optic still working if it is submerged in water and you can still find the rifle.
Details on Rifle Glass Tube Gas Purging
Another component of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less influenced by temp alterations and pressure differences from the outdoor environment which could potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
