Glass Info
Rifle scopes enable you to specifically aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adjusted to account for different environmental elements like wind and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have around 11 parts which are arranged within and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has determines where the reticle or crosshair lies in relation to the scopes magnification. It simply suggests the reticle is behind or ahead of the magnifying lens of the optic. Considering the most ideal style of rifle scope depends upon what sort of shooting you anticipate undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification 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 magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who want a clearer optic sight picture without area used up by the larger size FFP reticle
Magnification for Rifle Glass
The amount of zoom a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Optics
A single power rifle optic uses 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 optic can not fluctuate given that it is fixed.
About Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a configuration like 2-10×32. These numbers imply the zoom of the scope can be set between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adjustment is achieved 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 of Optics
Here are some suggested scope power settings and the distances where they could be efficiently used. Highly magnified optics will not be as useful as lower powered glass because too much zoom can be a negative aspect depending on your shooting distance. The same relates to extended ranges where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Info on Lens Coating
All modern-day rifle scope lenses are layered. Lens finishing is a crucial aspect of a shooting system when purchasing high end rifle optics and scope setups.
About Optic Lens Coatings – HD Versus ED
Some glass producers additionally use “HD” or high-definition lens finishings that employ various procedures, components, chemical substances, and polarizations to enhance numerous color ranges and viewable definition through the lens. This high-definition coating is typically used with more costly, high density glass which brings down light’s chance to refract through the lens glass. Some scope makers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over objects with hard shapes as light hits the item from particular angles.
Scope Lens Single Covering Versus Multi-Coating
Various optic lenses can also have various coverings used to them. All lenses typically 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 reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives several treatments, it can indicate that a producer is taking multiple actions to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally doesn’t necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment solutions and the quality of glass used in constructing the rifle scope.
Anti-water Rifle Optic Lens Finish
Water on a lens does not help with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Options for Installing Scopes on Firearms
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use toss levers which allow rifle shooters to quickly install and remove the optics.
Hex Key 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 a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is fine for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can ruin a day on the range and your costly optic by triggering fogging and producing residue inside of the scope tube. Most optics prevent humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Generally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are concerned about the optic still performing if it goes over the side and you can still recover the firearm.
What to Know About Optic Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the optic is less altered by temp changes and pressure distinctions from the external environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
